Comparative studies of angioscopy and ultrasound for the evaluation of arterial disease.

In this in vitro investigation, we studied the histopathological basis for intravascular ultrasound image interpretation and how this technique compares with fiberoptic angioscopy in assessing atherosclerosis. This article presents the sensitivity and specificity of these techniques in the recognition of arterial abnormalities. The relevance of these data in interventional therapeutic procedures and the clinical implications of intravascular imaging methods are also discussed.
