Humans are infected when arthroconidia in the soil are disturbed and dispersed into the air. Once inhaled, arthroconidia form spherules, which trigger a host cell-mediated immune response. If this response is adequate, it results in granuloma formation, halting the infection. However, an insufficient response leads to morphologic conversion into endospores that are capable of hematogenous and lymphatic dissemination to other organ systems. Given the airborne route of transmission, there is a propensity for pulmonary infections, which represent the most common disease manifestation of coccidioidomycosis. CT features of pulmonary involvement include nodules, lobar or segmental consolidation, and multifocal consolidation in the acute phase, which can occur with mediastinal adenopathy and/or pleural effusions. Extrapulmonary dissemination is rare, occurring in 1%-5% of patients. Musculoskeletal involvement is common in cases of dissemination, with discitis-osteomyelitis being a frequent manifestation, often demonstrating relative disk sparing analogous to that seen with tuberculosis or other causes of atypical infectious spondylitis. When osteomyelitis of the appendicular skeleton is juxta-articular, it can progress to septic arthritis, with fungal tenosynovitis and soft-tissue abscesses being less common musculoskeletal features. Neurologic involvement is frequent, with complications including meningitis, cerebritis, and abscess formation, which can induce vasculopathic and neuropathic sequelae, leading causes of morbidity and mortality in cases of dissemination. Other systems are less commonly involved, but conditions include pyelonephritis, peritonitis, lymphadenitis, and endocarditis. ^©RSNA, 2026 Supplemental material is available for this article.</p>","PeriodicalId":54512,"journal":{"name":"Radiographics","volume":"46 2","pages":"e250064"},"PeriodicalIF":6.2,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146088145","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}

Micropolling is a technique that uses short-form surveys that are sent more frequently than are traditional long-form surveys. This approach aims to collect longitudinal data with good engagement to better understand an individual practice environment. The authors developed a micropoll initiative within a single radiology institution with questions that targeted employee wellness and departmental priorities. Micropolls were sent at scheduled intervals via email to all radiology trainees and faculty. All data and anonymous comments were compiled and provided to the department chair to monitor the workplace environment and guide departmental initiatives. Thirteen pulse surveys were sent bimonthly over a 6-month period to 127 faculty and 62 trainees. Engagement was initially low, with an average of 11 faculty responses to the multiple-choice questions in surveys one to three. In later surveys, engagement increased to an average response rate of 35 for surveys six to 10. Engagement with trainees remained low and somewhat sporadic throughout the survey period, with seven trainees responding weekly on average. Engagement was higher with selection-based questions and decreased with free-text responses. After a short transition period, the periodic pulse survey became a successful way to gather data throughout the department, particularly among faculty. An appeal of this micropolling methodology is the repetition of questions at different time points to see trends in the department and measure responses to specific interventions or initiatives. ^©RSNA, 2026.</p>","PeriodicalId":54512,"journal":{"name":"Radiographics","volume":"46 2","pages":"e250080"},"PeriodicalIF":6.2,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145985970","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}

The spectrum of shoulder girdle injuries spans clavicle fractures, acromioclavicular joint separations, floating shoulder patterns, glenohumeral fracture-dislocations, glenoid fossa fractures, proximal humerus fractures, and scapulothoracic dissociations. Most fractures are treated conservatively with sling immobilization, and absolute surgical indications are limited to open and impending open fractures or neurovascular compromise. However, since injury severity correlates with instability, chronic pain, and functional impairment, high-grade disruptions may warrant surgical intervention when specific criteria are met. Classification systems-such as the Neer, Rockwood, and Ideberg-Goss frameworks-combined with measurements including the glenopolar angle, glenoid index, glenoid track, and metaphyseal head extension inform the surgical risk-benefit calculus and help determine optimal surgical techniques and exposures.

The choice of contrast agent is critical, as extracellular agents (ECAs) and hepatobiliary agents (HBAs [eg, gadoxetate]) have different strengths and weaknesses. ECAs are useful in depicting progressive centripetal enhancement (eg, hemangiomas), whereas HBAs are useful for identifying hepatocyte-containing lesions (eg, focal nodular hyperplasia) and offer high sensitivity for detecting hepatocyte-deficient lesions (eg, hepatic metastases). MRI with HBAs can result in uncertainty in distinguishing hemangiomas from metastases, as some hemangiomas are hypoenhancing at venous and transitional phases and both lesion types are hypointense at the hepatobiliary phase (HBP). There may also be uncertainty in distinguishing between hepatic adenomas and focal nodular hyperplasia if an ECA is used, necessitating a follow-up evaluation with an HBA. Additionally, HBAs can induce transient arterial phase motion, potentially obscuring arterial phase hyperenhancement. Hybrid agent imaging with gadobenate provides ECA-like behavior during dynamic imaging, but the HBP requires a 1-hour delay, often with a less robust HBP. A sequential dual-contrast agent protocol, imaging dynamically with an ECA followed by an HBA for HBP imaging, offers the advantages of both types of agents and is ideally suited for the initial characterization of FLLs. The authors describe the benefits and pitfalls of single-contrast agent FLL imaging, the rationale for dual-contrast agent FLL imaging, and the specifics of a dual-contrast agent protocol. Advantages of a dual-contrast agent technique are illustrated through case examples. The reader will be empowered to adopt a dual-contrast agent liver MRI protocol for greater diagnostic confidence and accuracy in initial FLL characterization. ^©RSNA, 2025 Supplemental material is available for this article.

Due to anatomic and physiologic differences, pediatric arteries are small and prone to vasospasm and dissection. Together with the lack of dedicated pediatric-specific equipment, the risks for arterial occlusion and thrombotic complications are significantly higher in children: up to 16% in those who weigh less than 15 kg. Detailed preprocedural planning, including selection of an appropriate arterial access site, periprocedural optimization, use of US guidance for arterial puncture, and meticulous postaccess care can help improve the success rate and reduce adverse outcomes. Although the transfemoral approach remains the conventional access route for the majority of pediatric angiographic examinations and transarterial interventions, alternative access routes including umbilical, radial, brachial, or axillary arteries can be useful in certain clinical scenarios. In neonates, the umbilical vessels are the preferred access site, and their use may prevent access-related complications in the extremities. In steno-occlusive aortoiliac conditions or in complex interventions involving downward-sloping visceral arteries, upper extremity access (eg, radial, brachial, and axillary, depending on artery size) can aid in the delivery of interventional devices. Compared with traditional transfemoral access, transradial access also has the advantage of allowing early ambulation. Use of intraprocedural unfractionated heparin and vasodilators can help reduce vasospasm and thrombosis in small arteries. The mainstay of treatment of arterial thrombosis is systemic anticoagulation therapy, while catheter-directed thrombolysis or thrombectomy is reserved for patients with critical limb ischemia resistant to anticoagulation medication. ^©RSNA, 2025 Supplemental material is available for this article.</p>","PeriodicalId":54512,"journal":{"name":"Radiographics","volume":"46 1","pages":"e250034"},"PeriodicalIF":5.5,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145783674","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}

Large vessel vasculitis (LVV) is divided into two main categories of giant cell arteritis (GCA) and Takayasu arteritis (TA). Although there are key distinguishing factors in their presentation, in reality, both conditions can behave nonspecifically with generalized symptoms making diagnosis challenging. Noninvasive imaging has a role in identifying, classifying, and staging LVV; often with a multimodality approach including US, CT and MRI with angiography, and fluorine 18 (¹⁸F)-fluorodeoxyglucose (FDG) PET/CT. The choice of imaging examination may vary according to patient presentation and local protocols, but international guidance recommends US as a first-line alternative to temporal artery biopsy in diagnosing GCA and mandates extracranial imaging when initial images are negative.

The estimated prevalence of PAVMs is approximately one in 2630 individuals, with hereditary hemorrhagic telangiectasia accounting for over 80% of cases. PAVMs are classified as simple, complex, or diffuse based on their angioarchitecture. Diagnostic evaluation involves transthoracic contrast-enhanced echocardiography for screening, chest CT for confirmation, and pulmonary angiography primarily for guiding embolization. Endovascular embolization is the preferred treatment and is typically performed with vascular plugs, although coils may be required for small or tortuous vessels. Postprocedural follow-up with CT is essential to detect persistent or new PAVMs. During pregnancy, PAVMs may enlarge and rupture, significantly increasing complication risks and necessitating close monitoring and treatment. Persistent PAVMs can develop after treatment due to four distinct mechanisms of reopening, each requiring a tailored management approach. The authors provide a comprehensive overview of PAVM angioarchitecture, step-by-step embolization techniques, and a comparative analysis of embolization devices, highlighting their advantages and limitations.

Its intricate anatomy and unique blood supply render it vulnerable to overlooked fractures and postfracture complications, often making for an exceptionally challenging radiologic appraisal. Radiographic diagnosis of a scaphoid fracture is particularly difficult because of the bone's complex geometric structure. Its numerous sulci, apices, ridges, and facets can resemble fractures, which may lead to unnecessary immobilization. A significant portion of the scaphoid is also encased in cartilage that restricts its capacity to develop callus, an imaging clue enduringly relied on in follow-up trauma radiography to confirm a fracture. There is no established agreement on the number of radiographic views. A minimum of three views is recommended, with most institutions adding a fourth. Both CT and MRI provide specific benefits for assessing cortical fractures and trabecular injuries, respectively, and can clarify cases for which clinical suspicion remains high. The scaphoid's distinctive distal-to-proximal blood flow increases the risk of osteonecrosis and abnormal healing following a fracture. Diagnosing osteonecrosis remains the radiologist's greatest challenge when evaluating the scaphoid. There are myriad studies proposing one imaging technique over another, without definite consensus on which is best. Currently, low signal intensity at T1-weighted MRI for osteonecrosis is the only generally accepted criterion. Among all complications, scaphoid osteonecrosis with nonunion is arguably the most difficult to treat.

To date, three cohorts comprising 14 organizations have participated in the program, which was built on the ACR ImPower continuous improvement framework. The organizations identified four main key drivers for prostate MR image quality: protocol optimization, patient preparation, personnel training, and performance monitoring and feedback. Examples of interventions designed to address these areas included incorporating protocol adjustments to comply with the Prostate Imaging Reporting and Data System version 2.1, changing the phase-encoding direction of diffusion-weighted and T2-weighted images, including artifact-resistant and artificial intelligence-enhanced sequences in the MRI protocol, developing and implementing patient preparation instructions regarding use of saline enema and dietary restrictions, training technologists on the importance of image quality and how to troubleshoot imaging artifacts, and performing systematic audits of the MRI examinations using the Prostate Imaging Quality System. The Collaborative also fostered a culture of continuous improvement and teamwork, which led to operational efficiencies and improved job satisfaction among frontline staff.
