Imaging Follow-up of Low-Risk Incidental Pancreas and Kidney Findings: Effects of Patient Age and Comorbidity on Projected Life Expectancy.

abstract：:Six cases of acoustic neurinoma are presented in which the tumor is supplied by branches of the external carotid artery, with or without supply from the internal carotid artery. A new angiographic protocol for the investigation of masses in the cerebellopontine angle is suggested. According to early results of the CT ...
