In recent decades, forensic radiology has declared itself as a new subspecialty capable of revolutionizing death investigation and research. A variety of postmortem imaging techniques have emerged. Postmortem CT (PMCT) is widely accepted around the world as a supplementary tool and, in specific cases and settings, an alternative to full autopsy. As its popularity grows, however, it is important for radiologists and pathologists to expand their understanding of the applications, benefits, and limitations of these techniques, as well as the unique nuances of postmortem imaging interpretation. This will ensure high-quality interpretations and avoid potential pitfalls that could result in premature or erroneous conclusions. The authors introduce the reader, particularly the radiologist, to the growing subspecialty of forensic imaging (focusing on imaging of the deceased), specifically focusing on PMCT and its applications in death investigation in both clinical and forensic settings. The authors also discuss the benefits and limitations of PMCT as well as important nuances of PMCT interpretation, emphasizing the similarities and differences between clinical and postmortem studies, the necessity of conducting thorough death investigations, and the importance of pursuing specialized education or training in postmortem imaging interpretation. Applications of more specialized imaging techniques to postmortem and forensic investigations are described, including developing research in this area. ©RSNA, 2025 Supplemental material is available for this article.","PeriodicalId":54512,"journal":{"name":"Radiographics","volume":"45 6","pages":"e240192"},"PeriodicalIF":5.2,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12142271/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144082092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 2024 Society of Radiologists in Ultrasound consensus conference established a first-trimester lexicon to highlight the importance of clear and concise language, which is incorporated and featured by the authors. With improved technologies and understanding of fetal development, first-trimester anatomic studies, between 11 weeks and 13 weeks 6 days gestation, are becoming more frequently used. While not a replacement for the second-trimester anatomic study, systematic evaluation of fetal anatomy at this early gestational age allows detection of 40%-70% of anomalies, whether structural or related to aneuploidy. All patients, regardless of age or baseline risk, should be offered screening and diagnostic testing for chromosomal abnormalities. A variety of prenatal screening approaches are available, each with strengths and limitations. Noninvasive prenatal testing with detection of fetal cell-free DNA can be performed in the first trimester and is the most sensitive and specific screening for the common fetal aneuploidies, but is not equivalent to diagnostic testing. Alternatively, serum analytes for maternal biomarkers in conjunction with nuchal translucency (NT) measurement can be used to calculate a risk estimate for common trisomies. Increased NT is the most common abnormality seen in the first trimester. Positive screening results, increased NT, or other anomaly at US should prompt genetic counseling and be confirmed with diagnostic testing (chorionic villus sampling or amniocentesis). Early detection of aneuploidy and structural anomalies allows counseling and informs decisions for pregnancy management. ©RSNA, 2025 Supplemental material is available for this article.","PeriodicalId":54512,"journal":{"name":"Radiographics","volume":"45 6","pages":"e240184"},"PeriodicalIF":5.2,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144082090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

US offers a noninvasive and cost-effective method for identifying and characterizing parathyroid lesions. Common causes include solitary parathyroid adenoma, multiple adenomas, and parathyroid hyperplasia. Despite its advantages, US has limitations, including difficulty in demonstrating deep-seated or ectopic glands. Radiologists must exercise caution in distinguishing parathyroid lesions from mimics such as thyroid nodules and lymph nodes using various imaging modalities including high-resolution neck US, scintigraphy, four-dimensional CT, and MRI. The authors focus on the role of US in evaluating parathyroid pathologic conditions, highlighting its advantages in concurrent detection of thyroid nodules while also discussing the complementary role and benefits of alternative imaging modalities. Common mimics encountered during imaging evaluation are briefly outlined. ©RSNA, 2025 Supplemental material is available for this article.","PeriodicalId":54512,"journal":{"name":"Radiographics","volume":"45 6","pages":"e240182"},"PeriodicalIF":5.2,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144183485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
