MR imaging assessment of clinical problems in rheumatoid arthritis.

Although MR imaging has been increasingly recognized as a useful tool in the diagnosis of early rheumatoid arthritis (RA) and in the assessment of disease activity, these applications have not yet been usually included in the routine management of this condition. Our goal is to review the current role of MRI in the everyday clinical management of patients with RA. The usefulness of MRI in the evaluation of articular and para-articular changes in specific locations, mainly the craniocervical region and the temporomandibular joint, are reviewed.

CT in hepatic cirrhosis and chronic hepatitis.

Cirrhosis is a diffuse liver disease with premalignant potential in which hepatocellular carcinoma (HCC) frequently develops. The hemodynamics of contrast material are the key to diagnosis of focal liver lesions with computed tomography (CT). Lesions with arterial-dominant vascularity, such as HCC, show brisk enhancement during the arterial phase, whereas lesions with portal blood supply can appear as hyperenhancing lesions in the portal phase.
