The study of the brain was carried out by SPECT with the radiopharmaceutical 99mTc-HMPAO (Ceretek).In the group with CABG, there was a statistically significant decrease in the CBF values in the region of the caudate nucleus on the right, in both occipital and parietal lobes (p = 0.004193). In the group with simultaneous interventions, a significant decrease in the CBF indices in the right occipital and left parietal lobes (p = 0.020672), an increase in the indices in the left temporal lobe (p = 0.011286) was revealed.CBF indicators in the group with simultaneous interventions are significantly lower than those in the group with CABG both in the preoperative and postoperative periods.The data obtained indicate that patients with combined atherosclerotic lesions of the coronary and carotid arteries have significantly lower values of the CBF in comparison with patients with isolated changes in the coronary arteries.Coronary artery bypass grafting and simultaneous surgical interventions on the carotid and coronary arteries under cardiopulmonary bypass may be accompanied by a significant decrease in regional cerebral blood flow in certain areas of the brain, and these changes in the CABG group can be traced in a larger number of analyzed areas.","PeriodicalId":51864,"journal":{"name":"Radiology Research and Practice","volume":"9 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75357215","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}

Craniofacial microsomia is one of the of maxillofacial dysostoses. This syndrome has a number of features associated with clinical manifestations which should be taken into account at steps of the diagnosis and treatment of such patients. The degree of mandibular hypoplasia in this pathology can vary from 0 to 3, and it is inversely proportional to the integrity of the articular disc on the side of the lesion. An increased mechanical load on a healthy joint leads to its dysfunction and dislocation of the articular disc at the healthy side. In addition to hypoplasia of bone structures, craniofacial microsomia is accompanied by subatrophy of masticatory muscles and that in couple leads to malocclusion and myodynamic imbalance. Before drawing up a treatment plan it is necessary to study the state of the TMJ on both sides using multislice computed tomography (MSCT) and magnetic resonance imaging (MRI). The approach to treatment should be individual, combined, staged, based on the severity of the symptom complex.","PeriodicalId":51864,"journal":{"name":"Radiology Research and Practice","volume":"200 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76966717","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}

For testing, we selected four software products based on convolutional neural networks, positioning themselves as a sensitive system for evaluating digital chest radiographs. An analytical validation method was used for clinical evaluation. For diagnostics, 3 data samples were formed with the identification of signs of diseases (sample 1–5150 radiographs, detection of pathological changes 3 %; sample 2–100 radiographs, detection of pathological changes 6 %; sample 3–300 radiographs, detection of the prevalence of pathological changes 50 %). None of the software products passed the AUC threshold of 0.811 on all three samples. In all three samples, all software products have high accuracy and high sensitivity in detecting round formations, which leads to rare cases of overdiagnosis and special cases of underdiagnosis. The use of digital X-ray image analysis systems based on artificial intelligence technologies is a promising direction for high-quality diagnostics, primarily when considering their young radiologists as an additional opinion.","PeriodicalId":51864,"journal":{"name":"Radiology Research and Practice","volume":"205 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82823381","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}

Two own observations are presented, unique in the absence of a clear cause of SI and the massiveness of the lesion. In the first case, a 10yearold girl was admitted to the hospital on about the 10th day of illness with complaints of undefined abdominal pain, about which she had already twice applied to other hospitals in Moscow. SI was suspected on ultrasound and confirmed on CT, and then the echographic dynamics of SI was followed for more than 2 months. Against the background of anticoagulant, antibacterial and symptomatic therapy, recovery was achieved.

All subjects underwent abdominal ultrasound with Dopplerography of the abdominal vessels, shear wave elastography, Arterial spin Labeling (ASL) — Perfusion of the liver by magnetic resonance imaging. Post-processing of ASL-perfusion images was carried out, their quantitative assessment in regenerative liver nodules and the parenchyma structure was carried out. It was found that for patients with liver cirrhosis according to Child-Pugh Class A, regardless of the degree of activity, the values of ASL-perfusion of the liver were 99.6 ± 1.8 ml/100g/min, with class B — 95.6 ± 4.9 ml/100g/min, with class C — 98.5 ± 2.6 ml/100g/min. To determine the diagnostic significance of liver ASL-perfusion, a generalized prognosis ratio ΔM = MNBF/ MHBF was calculated, where MNBF is a quantitative indicator of volumetric blood flow in the regenerative nodule, MHBF is a quantitative indicator of volumetric hepatic blood flow in the surrounding parenchyma. The results obtained by ASL-perfusion were compared with the data of shear wave elastography.For patients with viral liver cirrhosis the quantitative indicator of ASL-perfusion of the liver is less than 101.4 ml/100g/min. To predict the course of viral etiology cirrhosis, the prognosis ratio ΔM should be taken, and if ΔM > 1, this indicates a poor prognosis (fibrosis progression), if ΔM ≤ 1 — a favorable one (no fibrosis progression).

Materials and Methods We performed a retrospective observational study comparing patients undergoing CT scans for trauma during the 1st and 2nd lockdown periods compared to corresponding prepandemic months. During two lockdown periods, public places such as restaurants, libraries, parks, and shops across the province were shut down. Government-led messaging advised that people should stay at home and practice social distancing. The rate of trauma-initiated CT scans and the proportion of different types of traumas were compared between time periods. Results There was no significant difference in overall trauma-initiated CT scans between the prepandemic and pandemic levels. Motor vehicle collision (MVC) cases decreased from 18.2% to 15.6% during the first lockdown period (p = 0.049) and also reduced from 29.1% to 25.2% during the second lockdown period (p = 0.013). Trauma from falls increased from 19.1% to 27.5% (p = 0.036) during the first lockdown, despite no significant change during the 2nd lockdown. Furthermore, the percentage of stab injuries increased from 25.0% to 38.9% while blunt trauma decreased from 68.5% to 54.3% during two lockdowns (p = 0.015). Conclusion The total number of trauma-initiated CT scans did not significantly decrease during the lockdown periods. Stabbings and falls increased during lockdown periods while MVCs and blunt trauma decreased.","PeriodicalId":51864,"journal":{"name":"Radiology Research and Practice","volume":"54 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2022-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77608288","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}
