The complex anatomy of the male urethra, which traverses structures such as the prostate and corpus spongiosum, make it particularly susceptible to injuries and strictures compared with the female urethra. The clinical assessment of urethral abnormalities is often limited, necessitating the use of imaging studies for thorough evaluation. While traditional radiographic techniques such as retrograde urethrography and voiding cystourethrography enable visualization of the urethral lumen, they have limitations in the assessment of periurethral tissues. MR urethrography (MRU) has emerged as a noninvasive modality that offers detailed anatomic insights into the urethra and periurethral structures. The authors review the embryologic features and anatomy of the male urethra and the risk factors associated with male urethral diseases. In addition, helpful imaging methods are discussed, with specific emphasis on MRI as a comprehensive modality and on optimal techniques for MRU protocols. A range of urethral diseases are described and illustrated, and key points for reporting MRU findings are highlighted. ©RSNA, 2025 Supplemental material and the slide presentation from the RSNA Annual Meeting are available for this article.","PeriodicalId":54512,"journal":{"name":"Radiographics","volume":"45 9","pages":"e240164"},"PeriodicalIF":5.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144857051","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}

For the most common application, IBD, it is well established that gray-scale US and color Doppler US imaging (CDI) allow excellent assessment of the status of the bowel wall, blood flow to the bowel and mesentery, and the presence or absence of perienteric inflammatory fat. Although these techniques provide effective and accurate methods to assess the bowel, they are not always comprehensive. Bowel loops residing in the true pelvis may not be accessible from a transabdominal approach, and CDI is not sensitive at increased depths and in patients with obesity. Most important, CDI only shows fast-moving flow in large blood vessels, with a limited ability to show blood flow at the microvascular level. Bowel stiffness is also not included in a standard gray-scale assessment. Three readily available ancillary US techniques can be used to overcome these imaging challenges and to greatly improve detection of pathologic conditions and patient outcomes. These techniques are endovaginal US to visualize pathologic conditions in the deep pelvis, contrast-enhanced US to subjectively and objectively assess blood flow to the capillary level, and two-dimensional shear-wave elastography to determine bowel stiffness as a measure of disease chronicity. The authors provide a detailed description of the application of these techniques with case examples demonstrating the added benefit. ©RSNA, 2025 Supplemental material is available for this article.

While small collections usually resolve on their own, larger or more complex ones have a limited differential diagnosis. Varied surgical approaches to the lumbar spine may predispose patients to different types of fluid collections, including seromas, hematomas, pseudomeningoceles, abscesses, bone morphogenetic protein (BMP)-related collections, lymphoceles, and urinomas; thus, radiologists should be aware of the different types of anterior and posterior surgical approaches to lumbar spine interbody fusion. Hematomas and abscesses may occur with any surgical approach. Pseudomeningoceles most frequently result after posterior approach surgery, while urinomas and lymphoceles more likely develop after anterior approach surgery due to the close proximity of the surgical corridor to the nephroureteral system or lymphatics, respectively. Surgical implants or biologics used at surgery can lead to BMP-related collections; awareness of any implanted materials intraoperatively can be helpful at the time of interpretation. While MRI is most frequently used for identifying fluid collections in the postoperative spine, CT can serve as an important adjunct. CT myelography can be used to confirm or exclude the presence of a pseudomeningocele but may not be necessary if MRI shows a confirmatory flow jet, confirming leakage of cerebrospinal fluid into the pseudomeningocele. CT enhanced with intravenous contrast material during the excretory phase also allows confirmation of the presence of a urinoma. When the contents of a postoperative fluid collection remain uncertain, aspiration may be necessary. Accurate diagnosis of the type of postoperative collection is extremely useful in guiding patient management and determining prognosis. ©RSNA, 2025.","PeriodicalId":54512,"journal":{"name":"Radiographics","volume":"45 9","pages":"e240163"},"PeriodicalIF":5.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144857052","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}

Echogenic lesions are a commonly encountered finding on US images, with a wide spectrum of underlying causes. These include normal structures and normal variants such as the choroid plexus and cerebellar vermis, normal transmantle white matter tracts, and benign entities that should not be mistaken for disease, such as hyperechoic caudate nuclei and thalamostriate mineralizing vasculopathy. Many pathologic conditions associated with major morbidity and mortality also may appear echogenic on US images. These most commonly include germinal matrix hemorrhage; white matter injury; hypoxic-ischemic encephalopathy; and hemorrhagic, infectious, and ischemic lesions. These lesions may be differentiated by their location at the caudothalamic groove, in the periventricular or deep white matter, diffusely involving the white matter, involving the deep gray matter, in the peripheral parenchyma, or in the cerebellum. Use of a tailored gestational age- and location-based approach combined with salient clinical details and knowledge of the unique vulnerabilities and responses to perinatal stressors in the preterm and term period improve diagnostic confidence and enable radiologists to differentiate those echogenic lesions that require no further follow-up from those that require further imaging or laboratory workup and specialist referral. ©RSNA, 2025 Supplemental material and the slide presentation from the RSNA Annual Meeting are available for this article.","PeriodicalId":54512,"journal":{"name":"Radiographics","volume":"45 9","pages":"e240065"},"PeriodicalIF":5.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144979032","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}
