Scintigraphy with 99 Tc-DMSA can determine the presence, prevalence of areas of ischaemia and implications for renal function. OBJECTIVE : By radiopharmaceutical accumulation, to assess the function of the injured kidney and to establish the consistency of the scintigraphic images with the radiological findings of the OIS/OI AAST classification. MATERIAL AND METHODS : Scintigraphy with 99 Tc-DMSA was performed in the immediate posttraumatic period in 196 patients who had Grade I–IV organ damage according to the OIS/OI AAST classification. The shape, size, and contours of the kidneys were visually evaluated. Based on the calculation of the uniformity and intensity of the indicator inclusion in the parenchyma the relative (total) kidney function was established. The degree and localisation of kidney damage were revealed on the basis of primary ultrasound and MSCT results. RESULTS : In the acute period of injury, Grade I–II were characterised by diffuse irregular distribution of 99 Tc-DMSA (from 75.0 to 100% of cases), but with increasing area and volume of injury, focal scintigraphic symptoms appeared (up to 25.0% of cases).In Grade III–IV, localised or extended focal deformation of the image contour and reduction of the overall kidney function prevailed. Comparative evaluation of CT findings with visual scintigraphy data demonstrated symmetry of visual information with sufficient accessibility, perceptibility, accuracy and correlated with OIS/OI AAST classification. DISCUSSION: Scintigram interpretation involves the interaction of two components: visual perception and subject-specific knowledge of human anatomical structures. This significantly differentiates it from clinicians’ conventional conception of the diagnostic process. Semiotics in the images included diffuse and focal changes, the basis of which is a disorder of haemocirculation with impaired uptake of radiopharmaceutical in the kidney parenchyma. For Grade I–II, hypoactive areas indicating the absence of significant damage are typical. Grade III–IV are characterised by localised areas due to reduced volume of functioning parenchyma. CONCLUSION: Scintigraphy in blunt kidney trauma demonstrates haemocirculatory abnormalities in the organ and a decrease in the amount of functioning parenchyma. Comparison of radionuclide images with computer imaging has a high degree of identity. The type of scintigrams allows grading them according to the OIS/OI AAST degree systematisation, which standardises the interpretation of radiological findings to improve the objectivity and quality of the study reports. Assessment of overall renal function makes it possible to predict the rehabilitative outlook of the injured kidney and the need for correction.","PeriodicalId":489012,"journal":{"name":"Lučevaâ diagnostika i terapiâ","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135483783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method based on the integration into the angiograph system 3D-reconstruction of the heart converted to computed tomography (CT) in the form of a mask against the background of fluoroscopy. CT is an important stage of the intraoperative visualization technique (IVT). OBJECTIVE: The aim of the study was to adapt the protocol of CT examination of the heart with contrast to construct a partially segmented 3D-reconstruction of the heart on an angiographic complex for subsequent use during of the lead implantation in the CCS within the framework of the author’s IVT. MATERIALS AND METHODS : As part of the development of the IVT, 21 CT studies of the heart were selected from own database. The step of the gradient of the density difference of the contrasted blood is about 10 HU, the range of the difference of densitometric parameters of the «left ventricle (LV) — right ventricle (RV)» from 0 HU to 200 HU. As well as selected 11 CT studies of the heart. The step of the gradient of the difference of densitometric indicators the contrasted blood in «the RV cavity — myocardium» is about 10 HU, the range is from 0 HU to 100 HU. All CT scans are alternately loaded into the angiograph, followed by the creation of a 3D model of the heart using basic software. RESULTS: It’s necessary to exceed the degree of contrast of the LV cavity over the RV cavity by at least 80 HU to perform partial segmentation on the left and right chambers of a 3D-model of the heart in an angiographic complex that does not have a specialized segmentation module. A sufficiently large part of the left ventricular cavity (LV) disappears with a smaller gradient when the right ventricular cavity (RV) is suppressed. The minimum gradient of «the ventricular cavity — myocardium» is at least 20 HU. The boundaries of the right ventricular edge of the interventricular septum (IVS) are not visualized with a smaller contrast gradient. It’s important for determining the insertion place of the lead into the IVS. CONCLUSION : It’s necessary to exceed the contrast of the LV cavities above the RV cavity by at least 80 HU, the RV cavity above the myocardium by at least 20 HU to perform partial segmentation on the left and right chambers of a 3D-model of the heart in an angiographic complex that does not have a specialized segmentation module","PeriodicalId":489012,"journal":{"name":"Lučevaâ diagnostika i terapiâ","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135482753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, accurate quantitative values may be useful to assess anatomical or physiological changes in the lungs in patients with previously treated COVID-19 infection. OBJECTIVE: To test a quantitative semi-automated algorithm for CT imaging in patients with confirmed COVID-19 infection and to compare the results to MR lung perfusion after coronavirus infection. MATERIALS AND METHODS : The data from 100 chest CT scans of patients with COVID-19 were retrospectively analyzed. 3D segmentation of the lungs was carried out with automatic counting of the number of separated pixels in each slice. For quantitative data analysis, classification based on the density value of each pixel according to the Hounsfield scale was used. The obtained data were compared with quantitative parameters of pulmonary MR perfusion in these patients. Statistics . Generalized additive model with beta distribution, Spearman correlation coefficient was used, Benjamini-Yekuteli correction was used to correct obtained p-values. Comparisons were determined as statistically significant when p<0.05. RESULTS : There was a correlation between quantitative CT data (fractions of pixels corresponding to non-ventilated and hypo-ventilated lung tissue) and the distribution of CT data into groups according to an empirical visual scale. We obtained a correlation between the functional perfusion parameters and the CT images: rMTT — 0.35 (p=0.001), rPBF — 0.23 (p=0.038) and rPBV — 0.35 (p=0.001). DISCUSSION: Using the algorithm of quantitative semi-automatic processing of CT-images suggested in this work allows to obtain numerical data, objectively reflecting percentage of affected lung tissue, that is especially relevant for diagnostics of COVID-19 pneumonia. The obtained correlation between functional perfusion parameters and CT picture can be potentially a marker of the lung pathological changes after COVID-19 pneumonia, that requires further investigations.

Children’s TBI is associated with a number of characteristics that distinguish it from adults. Although the death rate associated with TBI has decreased over the past 2 decades, the disability of children who survived TBI continues to have a significant impact on the economy and public health of society as a whole. OBJECTIVE: To show the possibilities of computed tomography and magnetic resonance imaging in the diagnosis of traumatic diffuse axonal injuries in infants and young children. MATERIALS AND METHODS : In this work, we analyzed the CT and MRI data of 1334 children under 3 years of age with acute TBI who were treated at the Clinical and Research Institute of Emergency Pediatric Surgery and Trauma (730 boys, 604 girls). The age of the children was from 23 days to 3 years, the average age was 1 year 6 months. Computed tomography scans were performed on a 128-slice Ingenuity Elite scanner (Philips). Scanning of the area of interest (head + cervical spine) was carried out with the maximum possible reduction in indicators to minimize the radiation dose, including the iDose4 program. MRI was performed on a Phillips Achieva 3 T scanner with multiplanar T1- and T2WI, 2D and 3D isotropic images, FLAIR, SWI, DWI/DTI, and magnetic resonance angiography (MRA). No contrast enhancement was applied. Statistics: data processing was carried out using the GraphPad Prism 9 software package. The computing and graphic capabilities of the Excel spreadsheet editor were used. To compare the mean values of the data samples, ANOVA analysis of variance wasused; differences were considered significant at a significance level of p<0.05. RESULTS : 824 (61.8%) of 1334 children had a concussion, 510 (38.2%) had traumatic injuries of skull and brain from uncomplicated cephalohematomas and linear fractures to massive intracranial hematomas and total brain edema. Diffuse axonal injuries(DAI) type I and II on CT, further confirmed by MRI, were detected in 32 (6.27%) of all 510 children with TBI. 19 out of 32 hada combination with brain contusions, 13 with epi — and / or subdural hematomas of a small volume. MRI was performed in 89 out of 510 children under 3 years of age with intracranial injuries, in whom CT was initially performed. DAI of various types were detected by MRI in 92.13% (82/89) of the patients. DISCUSSION: DAI is one of the most common types of TBI, occurring in both mild and severe forms, and is a brain injury characterized by axonal disruption, resulting in lesions of white matter tracts over a wide area. Taking into account the fact that children with TBI were admitted to the institute with a significant spread (from 1 hour to 7 days), the initial CT scan was performed no later than one hour after admission and was supplemented by MRI.

Further research is required for optimization of lung perfusion’s design parameters’ methods in order to implement those in clinical practice. OBJECTIVE: To determine the possibilities of an alternative method for evaluation of relative lung perfusion using three-dimensional ultrafast contrast-enhanced MRI on patients with previously treated COVID-19 pneumonia. MATERIALS AND METHODS : We examined 100 patients (28 male and 72 female, aged 22 to 70) who had laboratory-confirmed COVID-19 infection. The research was conducted using the three-dimensional ultrafast dynamic contrast-enhanced MRI based on 3D T1-weighted images. During the postprocessing, we received the values of rPBF (relative pulmonary blood flow), rPBV (relative pulmonary blood volume), and rMTT (relative mean transit time). Statistics . For non-linear dependence modelling we used natural spline transformation for time and interaction effect with a group. Intergroup comparison on integral measures was based on Kruskall-Wallis test (χ 2 ), pair comparisons were based on Conover’s test (Δ). For multiple hypothesis testing correction, we used the false discovery rate (FDR). Comparisons were determined as statistically significant when p<0.05. RESULTS: The differences in obtained values of lung perfusion among patient groups were confirmed both quantitatively (by rMTT, rPBV, rPBF) and qualitatively (by building the curves of contrast agent accumulation). Patients with previously treated COVID-19 demonstrate slower contrast agent transit and increased relative lung blood volume. Their accumulation curves have qualitative differences as well. DISCUSSION: We suggest a new method of evaluation of lung perfusion indicators in patients with previously treated COVID-19. We conducted an intergroup analysis based on the degree of lung damage during the acute phase of COVID-19 (with no infiltrativechanges, with minor lung damage, and major lung damage). The intergroup differences found are more significant for patients with lung damage (both minor and major) than for patients with no infiltrative lung changes during the acute phase of COVID-19.

The basis for improving results is the improvement of early radiological diagnosis of these diseases. OBJECTIVE : Of this study was to systematize the approaches in the radiodiagnosis of acute abdominal surgical infection. MATERIALS AND METHODS : The study analyzed the results of studies of 300 observations (men — 182, women — 128) aged 36 to 72 years who were treated at the Budgetary Institution «Surgut Regional Clinical Hospital» in the period from 2019 to 2022. The mean age of the patients was 49.2 years (59.7 years for men and 51 years for women). In the course of the study, a comparative analysis of the results of various methods of radiological examination in acute abdominal surgical infection was carried out, and key aspects of the radiodiagnosis algorithm were presented. Statistics . Statistical processing and systematization of these methods of radiation diagnostics was carried out with the calculation of sensitivity and specificity. The description of categorical variables was carried out using absolute values and a fraction of the whole — n (%). The results of calculating the indicators did not reveal significant differences in the group of men and women examined. RESULTS: At the initial stage of diagnosis, two main X-ray morphological syndromes of acute abdominal surgical infection were identified: a widespread inflammatory process (peritonitis and pancreatic necrosis) and a delimited inflammatory process (abscesses of various localizations). Based on the syndromic approach, not only the nosological diagnosis of this pathology wassubsequently carried out, but also approaches to the tactics of surgical treatment of patients were determined. DISCUSSION : The choice of the method of radiation examination of these patients, justified by the leading clinical and radiological syndrome, leads to early diagnosis and treatment of acute abdominal surgical infection.","PeriodicalId":489012,"journal":{"name":"Lučevaâ diagnostika i terapiâ","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135483784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OBJECTIVE: The aim of this paper is to evaluate the possibilities of 3D modeling in the surgical treatment of pancreatic diseases according to the literature. MATERIALS AND METHODS : Literature searched in Russian and English for the period from 2017 to 2022 in Medline/PubMed, RSCI/Elibrary, CyberLeninka, Google Scholar databases. The search was conducted on the keywords: pancreas, chronic pancreatitis, pancreatic cancer, pancreatic resection, computed tomography, 3-D modeling, 3-D reconstruction, surgical planning, surgical intervention, pancreas, chronic pancreatitis, pancreas cancer, pancreatectomy, computed tomography, 3-D modeling, 3D reconstruction, surgical planning. RESULTS : 49 publications on various aspects of the use of 3D modeling in pancreatic surgery were included in the final analysis. The diagnostic value of building three-dimensional models in assessing the resectability of pancreatic tumors, identifying individual topographic and anatomical features of the pancreatobiliary zone, which should be taken into account during surgery to avoid intra- and postoperative complications, is shown. Examples of a description based on 3D modeling of rare vascular anomalies and cysts that are not visualized according to standard computed tomography in patients who are scheduled for pancreatic surgery are presented. The importance of postoperative 3D modeling of the pancreas for assessing the adequacy of the surgical intervention and early detection of possible complications of the operation is indicated. CONCLUSION : 3D modeling is an innovative and promising diagnostic method that allows increasing the information content of standard computed tomography in pancreatic surgery. 3D models make it possible to select patients for pancreatic resection and substantiate the most optimal surgical strategy. In the future, we should expect an improvement in the results of surgical treatment of pancreatic tumors and complicated pancreatitis.","PeriodicalId":489012,"journal":{"name":"Lučevaâ diagnostika i terapiâ","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135646093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
