Dentistry is divided into several specialties, each offering unique treatments, such as endodontics, implantology, oral surgery, and orthodontics. CT and MR images after dental treatment reveal a variety of hard- and soft-tissue changes and dental materials, which often cause image artifacts. Familiarity with posttreatment changes and dental materials is crucial to avoid misinterpretation of image artifacts as true pathologic features, identify complications, and evaluate for recurrent disease. It also is necessary to be aware of conditions that mimic posttreatment changes and know how to differentiate them at imaging. The authors focus on the imaging of expected and unexpected post-dental treatment changes and characteristics of dental materials on CT and MR images in the head and neck region. The article is divided into five sections: <i>(a)</i> imaging after dental implant treatment, <i>(b)</i> imaging after oral surgery, <i>(c)</i> imaging after endodontic treatment, <i>(d)</i> imaging after orthodontic treatment, and <i>(e)</i> imaging effects of dental treatments. Strategies are provided for distinguishing true pathologic features from posttreatment changes, and the importance of understanding dental procedures, the materials used, and their appearances at radiologic imaging is highlighted. Ultimately, this knowledge can enhance radiologists' ability to interpret complex posttreatment imaging findings, improve diagnostic accuracy, and facilitate effective treatment planning for patients with a history of dental procedures. <sup>©</sup>RSNA, 2025 Supplemental material is available for this article.</p>","PeriodicalId":54512,"journal":{"name":"Radiographics","volume":"45 2","pages":"e240072"},"PeriodicalIF":5.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030344","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}

It is used to increase specificity by decreasing the number of breast biopsies. It has been validated for mammography, breast US, and emerging indications for use in contrast-enhanced breast MRI. Despite the long-term use of category 3 and numerous published studies that evaluate characteristic imaging findings appropriate for this category, there is still misuse and confusion regarding its accurate use. Imaging findings classified as category 3 require short-term follow-up to assess stability and identify changes that may warrant a biopsy for early diagnosis of breast cancer. Category 3 should not be used in a screening study without a comprehensive diagnostic evaluation that may reveal suspicious features or downgrade a finding to benign. In mammography, category 3 findings are validated for grouped round calcifications, oval circumscribed masses, and nonpalpable asymmetries. In US, category 3 can be applied to oval circumscribed parallel solid masses and complicated cysts. Category 3 can be assigned to clustered microcysts when they are very small or deep in the breast. Recent studies have yielded characteristic findings appropriate for MRI category 3 that are expected to be included in the sixth edition of the BI-RADS atlas. These include oval circumscribed masses with associated T2-hyperintense signal, focal non-mass enhancement, and foci of enhancement with associated T 2-hyperintense signal. Surveillance with short-interval imaging enables radiologists to monitor findings and act early when a change is detected. <sup>©</sup>RSNA, 2024 Supplemental material is available for this article.

Thermal ablation, however, has become an accepted alternative treatment of small renal neoplasms with excellent oncologic outcomes. The National Comprehensive Cancer Network guidelines include thermal ablation as a treatment strategy for managing T1a and select T1b masses. Other potential locoregional treatments for malignant and benign renal masses are emerging. Stereotactic body radiation therapy (SBRT) is gaining traction in the management of select localized renal masses and can be considered in patients who are not surgical candidates. Imaging findings after SBRT differ from those after thermal ablation. As this technique becomes more widely used, the temporal evolution of post-SBRT changes needs to be understood to correctly identify local tumor progression. Renal artery embolization is accepted as safe and effective for patients with renal angiomyolipoma. It can also be used in the management of renal cell carcinoma as an adjunct to definitive treatment or for palliation in advanced disease. With the growing acceptance of local-regional treatment of renal masses and the corresponding number of related patients undergoing surveillance and postablation imaging, the diagnostic radiologist will have greater responsibility in the appropriate interpretation of follow-up imaging to accurately assess normal postprocedural findings and define oncologic outcomes. Such interpretations should be based on understanding of the procedure and related imaging findings, both acutely and in the years after treatment. Procedural complications and recurrent tumor are identifiable based on deviations from the expected course. <sup>©</sup>RSNA, 2024 <i>Supplemental material is available for this article.</i></p>","PeriodicalId":54512,"journal":{"name":"Radiographics","volume":"45 1","pages":"e240093"},"PeriodicalIF":5.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142866441","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}

Other vascular abnormalities including infection, acute limb ischemia, and vasculitis are discussed.
