ABSTRACT

Since the introduction of echoencephalography in the early 1950s, ultrasonic techniques have evolved dramatically. Ultrasound (US) imaging is now considered an integral part of the evaluation of patients with cerebrovascular disease (CVD), because it is noninvasive, relatively inexpensive, accurate, and readily accessible. This chapter provides the basics of US and summarizes diagnostic and therapeutic applications of US in interventional neuroradiology.
