Higher PSA levels are generally associated with more aggressive cancers and an increased risk of cancer-specific mortality. In this report, we present an unusual case of primary aggressive prostate cancer characterized by unexpectedly low PSA levels, despite the presence of multiple lumbar bone metastases at the time of diagnosis. It is extremely uncommon to have a low PSA level at the time of initial prostate cancer diagnosis, especially in cases that are non-recurrent, and even more so for adenocarcinomas without neuroendocrine differentiation. This report highlights the challenges in accurately diagnosing disease using CT and MRI findings when confronted with atypically low PSA patterns, necessitating invasive diagnostic approaches such as transperineal biopsy following abdominoperineal resection in a patient with a colostomy.","PeriodicalId":101329,"journal":{"name":"Journal of the Korean Society of Radiology","volume":"86 3","pages":"407-412"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12149883/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144277315","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}

Cancer visibility was determined based on reports from experienced radiologists. Two expert radiologists assessed mammographic findings and breast imaging reporting and data system (BI-RADS) categories by consensus for cases of visible cancer. AI-CAD results were reviewed to determine whether AI-CAD correctly marked the cancer site. AI-CAD detection rates were analyzed according to mammographic findings, BI-RADS categories, lesion size, histologic grade, lymph node involvement, and stage. The concordance between the findings of AI-CAD and those of experienced radiologists was also assessed. Mammographically occult cases were defined as those with negative mammographic findings by two radiologists.Results: AI-CAD detected 81.4% (219/269) of cancers, with higher detection rates occurring for larger lesion sizes, high histologic grades, lymph node involvement, and advanced stages. AI-CAD detection rates were higher for architectural distortion, mass, and calcification, but lower for asymmetry. Detection rates increased with higher BI-RADS categories and a higher number of mammography findings. Concordance between the assessment of AI-CAD and that of experienced radiologists was 88.5% (238/269). AI-CAD correctly detected 19.4% (6/31) of mammographically occult cases.Conclusion: AI-CAD detected 81.4% of cancers, with substantial concordance with the findings of experienced radiologists. It correctly identified 19.4% of mammographically occult cases.","PeriodicalId":101329,"journal":{"name":"Journal of the Korean Society of Radiology","volume":"86 3","pages":"391-406"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12149878/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144277296","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}

PanNETs with intraductal growth are considered extremely rare, and ductal involvement in NETs has been reported to correlate with aggressive clinical behavior. A 67-year-old male was referred to our hospital for further evaluation of a pancreatic tumor. Various imaging modalities, including ultrasonography, contrast-enhanced CT, MRI, and endoscopic ultrasonography (EUS), demonstrated a well-defined pancreatic mass in the head and body, primarily located within the main pancreatic duct with extension to the main portal vein. Histological diagnosis from an EUS-guided biopsy revealed a grade 3 well-differentiated NET. The patient was scheduled for surgery; however, multiple additional bone metastases were identified on 18F-fluorodeoxyglucose PET/CT. Although the presence of intraductal growth and portal vein invasion is uncommon in PanNETs, aggressive workup and treatment are essential in such cases.","PeriodicalId":101329,"journal":{"name":"Journal of the Korean Society of Radiology","volume":"86 3","pages":"438-444"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12149879/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144277298","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}

Motion reduction by breathing control schemes or scan time acceleration by k-space undersampling are two accessible approaches in clinical imaging. Parallel imaging is an indispensable everyday technique with well-known characteristics, but with drawbacks that limit acceleration factors to ≤4. Compressed sensing exploits the data sparsity of MR images, and pseudorandomly undersamples k-space data to iteratively reconstruct images using sophisticated complex computations within highly accelerated scanning time. Albeit, this is with long reconstruction time and complexity in parameter optimization. Deep learning reconstruction uses pretrained and validated convolutional neural networks to reconstruct undersampled data, with the main tasks being image acceleration, denoising, and superresolution. While promising, deep learning reconstruction requires further testing and practical experience with model stability, generalizability, and output image fidelity.","PeriodicalId":101329,"journal":{"name":"Journal of the Korean Society of Radiology","volume":"86 3","pages":"307-320"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12149871/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144277297","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}

Consequently, early detection and accurate assessment are essential. Grayscale US has traditionally been used for evaluating hepatic steatosis; however, its limitations include reduced sensitivity for mild cases and subjective interpretation. In addition to controlled attenuation parameter, two-dimensional attenuation-based techniques have been recently introduced to quantify US beam attenuation for assessing hepatic steatosis, demonstrating high diagnostic accuracy and reproducibility while addressing some of the limitations of grayscale US. To enhance diagnostic precision and reduce measurement variability, the standardization of examination protocols, including measurement processes, is necessary. Additionally, further research is needed to explore the role of a multiparametric approach combining attenuation-based techniques with elastography in predicting disease progression. This review examines the principles, recent research findings, and future perspectives on attenuation-based quantitative evaluation of hepatic steatosis using US.","PeriodicalId":101329,"journal":{"name":"Journal of the Korean Society of Radiology","volume":"86 3","pages":"321-334"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12149873/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144277294","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}
