It is performed most often by nuclear medicine technologists with imaging studies interpreted by a radiologist.1 Physicians interpreting these studies must understand the indications, contraindications, and reasons for false-positives and false-negatives to accurately correlate findings with pathology. It is essential that physicians interpreting hepatobiliary scintigraphy studies understand the anatomy, physiology, and how patient preparation can impact imaging findings to best correlate findings to biliary pathology. Understanding these concepts provides the best patient care and treatment options.","PeriodicalId":29694,"journal":{"name":"Contemporary Diagnostic Radiology","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45691845","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}

Thyroid nodules are typically first assessed with ultrasound and followed up with fine needle aspiration (FNA), if indicated. Thyroid imaging reporting and data system (TI-RADS) is designed to improve diagnostic accuracy and risk stratification, leading to a decrease in unnecessary FNA procedures and follow-up examinations. TI-RADS assigns scores in five categories—composition, echogenicity, shape, margins, and echogenic foci—which are totaled to yield a final overall TI-RADS score and classification. The final classification has been shown to correlate with the likelihood of malignancy.","PeriodicalId":29694,"journal":{"name":"Contemporary Diagnostic Radiology","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44036685","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}

It is considered the most common idiopathic interstitial pneumonia, falling under the broad category of interstitial lung disease (ILD). The key imaging finding in IPF on high-resolution CT is the typical usual interstitial pneumonia (UIP) pattern. However, some of the imaging findings may overlap with other ILDs and conditions, so these hallmark findings and overlapping imaging findings have been reviewed. Given the progressive and debilitating nature of disease, it is important for the radiologist to be able to identify the key imaging characteristics of UIP to help aid in the diagnosis of IPF and early initiation of treatment, which has been shown to preserve lung function and improve outcomes.
