ACR Appropriateness Criteria Renal Cell Carcinoma Staging.

Renal cell carcinoma accounts for 2%-3% of all visceral malignancies. Preoperative imaging can provide important staging and anatomic information to guide treatment decisions. Size of the primary tumor and degree of local invasion, such as involvement of perinephric fat or renal sinus fat, and tumor thrombus in renal veins and inferior vena cava are important detriments to local staging of prim...

ACR appropriateness criteria jaundice.

A fundamental consideration in the workup of a jaundiced patient is the pretest probability of mechanical obstruction. Ultrasound is the first-line modality to exclude biliary tract obstruction. When mechanical obstruction is present, additional imaging with CT or MRI can clarify etiology, define level of obstruction, stage disease, and guide intervention. When mechanical obstruction is absent,...

ACR Appropriateness Criteria(®) myelopathy.

Myelopathy is a problem that requires imaging to distinguish among numerous specifically treatable causes. The first priority is to determine mechanical stability after trauma. Next, it is crucial to distinguish intrinsic disease from extrinsic compression-for example, by epidural abscess. Osteophytes or disc extrusions and metastatic compression are the most common causes of extrinsic lesions....
