Head orientation should be considered in ultrasound studies on carotid artery distensibility.

Abstract

INTRODUCTION During ultrasound distensibility assessment of the carotid artery, the patient's head is usually rotated sideward and slightly upward to optimize visibility of the carotid segment. Head rotation may affect vessel length and thus the longitudinal strain of the arterial segment. Because the longitudinal and circumferential mechanical behaviour of… (More)
