Hepatocellular carcinoma: MR imaging.

Thirty patients with hepatocellular carcinoma (HCC) were examined by MRI. Distinctive findings of HCC such as the presence of fatty degeneration, a capsule, mosaic pattern, daughter nodules and tumor thrombi in major veins were noted in 6, 13, 1, 10 and 9 cases or 20%, 43%, 3%, 33% and 30% respectively.

Disorders of esophageal motility.

Patients with esophageal motility disorders usually have dysphagia and many also have chest pain similar to angina. The diagnosis is suggested by the clinical presentation, and supporting evidence is often provided by contrast roentgenography. Esophageal manometry is usually necessary to confirm the diagnosis.
