All patients were disqualified from surgical treatment due to age, comorbidities, or history of nephrectomy. Diagnosis was confirmed by computed tomography (CT)-guided core needle biopsy that was performed 2-4 weeks before cryoablation.Results: Twenty-five patients underwent CT-guided cryoablation of T1a renal cancer. The mean age of the patients was 77 years (43-91 years). The mean diameter of lesions was 27 mm (15-40 mm). None of the patients presented with local or distant recurrence within the mean 12-months of follow-up period (100% progression-free survival).

Reducing the scanning time has become a critical area of focus in MRI, aiming to enhance patient comfort, reduce motion artifacts, and increase MRI throughput. In the past 5 years, artificial intelligence (AI)-based algorithms, particularly deep learning models, have been developed to reconstruct high-resolution images from significantly fewer data points. These new techniques significantly enhance MRI efficiency, improve patient comfort and lower patient motion artifacts. Improving MRI throughput with lower scanning duration increases accessibility, potentially reducing the need for additional MRI machines and associated costs. Several fields can benefit from shortened protocols, especially for routine exams. In oncologic imaging, faster MRI scans can facilitate more regular monitoring of cancer patients. In patients suffering from neurological disorders, rapid brain imaging can aid in the quick assessment of conditions like stroke, multiple sclerosis, and epilepsy, improving patient outcomes. In chronic inflammatory disease, faster imaging may help in reducing the interval between imaging to better check therapy outcomes. Additionally, reducing scanning time could effectively help MRI to play a role in emergency medicine and acute conditions such as trauma or acute ischaemic stroke. The purpose of this paper is to describe and discuss the advantages and disadvantages of introducing deep learning reconstruction techniques to reduce MRI scanning times in clinical practice.","PeriodicalId":94174,"journal":{"name":"Polish journal of radiology","volume":"89 ","pages":"e443-e451"},"PeriodicalIF":0.0,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11497590/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142515580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PCD-CT devices are expected to provide advantages in dose reduction, tissue specificity, artifact-free imaging, and multi-contrast demonstration capacity. Noise reduction and increased spatial resolution are expected using PCD-CT, even under challenging scanning conditions. Some experimental or preliminary studies support this hypothesis. This pictorial review illustrates the features of PCD-CT systems, particularly in the interventional field. PCD-CT offers superior image quality and better lesion discrimination than conventional CT techniques for various conditions. PCD-CT shows significant improvements in many aspects of vascular imaging. It is still in its early stages, and several challenges have been identified. Also, PCD-CT devices have some important caveats. The average cost of these devices is 3 to 4 times higher than conventional CT units. This additional cost must be justified by improved clinical benefits or reduced clinical harms. Further investigations will be needed to resolve these issues.","PeriodicalId":94174,"journal":{"name":"Polish journal of radiology","volume":"89 ","pages":"e433-e442"},"PeriodicalIF":0.0,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11497591/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142515582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, we decided to develop a methodology for measuring the volume of the coronary sinus in multi-detector CT and to try to apply it in practice.Material and methods: Forty-nine patients (22 men) were included in this research, with a mean age of 70.08 ± 13.6 years. Scanning with retrospective ECG-gating was performed using a Toshiba Aquilion 64 (slice: 0.5 mm; helical pitch: 12.8; rotation time: 0.4 s). 80 ± 20 cm3 of non-ionic contrast was administered to each patient. The volume of coronary sinus and other data measurements were performed using Vitrea 2 workstations. The organ volume measurement function was used to measure volume objects in CT scans. To standardise the measurements, they were all performed to the place where the vein of Marshall reaches the coronary sinus. In cases of loss of vein of Marshall, the first lateral vein was used as the junction between the coronary sinus and the great cardiac vein.Results: The coronary sinus volume varied from 0.96 cm3 to 8.52 cm3. The average volume was 3.71 ± 1.64 cm3. There was a significant correlation between end diastolic volume and coronary sinus volume (r = 0.33, p = 0.02). In most cases the quality of visualisation was good - the average was calculated as 4.16 ± 0.87.

An endodontically treated tooth index (ETTI) was used to evaluate ET. Once apical periodontitis was recognised, the size, extent, and ratio of adjacent anatomical structures were assessed using the complex periapical index (COPI).Results: Analysis of the CBCT images showed that ET was performed in 9.9% of the teeth examined, of which 52.7% of the canals were treated correctly, while 28.1% of the root canals were found to be underfilled, 6.8% were overfilled, 9.3% of the root canals were not obturated at all, and in 3.1% of the teeth examined, the filling material was only visible in the pulp chamber. Apical periodontitis was observed in 6% of all teeth examined, while the percentage of teeth following ET was 38.5%.Conclusions: The quality of the ET provided to the Polish subpopulation is unsatisfactory. Lack of root canal filling homogeneity is a significant risk factor for ET failure. Improper ET and poor quality of crown restoration after ET have an impact on the increased risk of occurrence, size, degree of root coverage, and extent of inflammatory periapical lesions in relation to adjacent anatomical structures.","PeriodicalId":94174,"journal":{"name":"Polish journal of radiology","volume":"89 ","pages":"e391-e401"},"PeriodicalIF":0.0,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11384213/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142305133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
