Embolisms originating in extra-cranial systemic arteries, and attributable either to cardiac or non-cardiac pathology, are a substantial cause of patient illness and demise. Dislodged emboli from a source can obstruct various peripheral and visceral arteries, leading to ischemia. The upper extremities, abdominal viscera, and lower extremities frequently experience noncerebral arterial occlusions. The progression of ischemia to tissue infarction in these regions may mandate procedures like limb amputation, bowel resection, or nephrectomy. For strategic treatment of arterial emboli, the identification of their source is crucial. This report assesses the appropriateness of imaging modalities used to locate the initiating site of the arterial embolism. Suspected embolic arterial occlusions of the upper extremities, lower extremities, mesentery, kidneys, and a multi-organ pattern are detailed within this document.

As thoracoabdominal aortic pathologies, such as aneurysms and dissections, become more frequent, and the sophistication of endovascular and surgical treatments rises, diligent imaging follow-up of affected patients continues to be critical. Careful tracking of thoracoabdominal aortic disease cases, untreated, is critical to identifying any shifts in aortic size or morphology, which might signify rupture or other detrimental consequences. For patients who have had endovascular or open aortic surgical repair, follow-up imaging is essential to evaluate for complications, including endoleaks or the reappearance of the initial disease. CT angiography and MR angiography are the most preferred imaging options for monitoring thoracoabdominal aortic pathology in the majority of cases, largely due to the significant quality of the imaging data they generate. The complexity of thoracoabdominal aortic pathology, including its potential consequences, often requires imaging the chest, abdomen, and pelvis in most instances. The ACR Appropriateness Criteria, evidence-based guidelines, are updated annually for specific clinical conditions by a multidisciplinary expert panel. Guideline development and revision procedures provide a framework for the systematic examination of medical literature published in peer-reviewed journals. For evidence evaluation, established methodology principles, in particular the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method, are adapted. The RAND/UCLA Appropriateness Method User Manual outlines the methodology for determining whether imaging and treatment approaches are suitable for particular clinical circumstances. When peer-reviewed research is scarce or unclear, subject matter experts frequently serve as the primary evidence base for recommendations.
Highly heterogeneous renal tumors, known as renal cell carcinoma, display a range of biological behaviors. In the context of renal cell carcinoma, pretreatment imaging requires the precise determination of the primary tumor size, the presence of nodal disease, and the extent of distant metastatic spread. Key imaging modalities for renal cell carcinoma staging include CT and MRI. Tumor extension into the renal sinus and perinephric fat, involvement of the pelvicalyceal system, invasion of the adrenal gland, involvement of the renal vein and inferior vena cava, and the presence of metastatic adenopathy and distant metastases, are key imaging features that impact treatment strategies.
