An intracavitary convex array probe for detecting internal carotid artery disease / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To assess the value of an intracavitary convex array probe in detecting internal carotid artery (ICA) disease.</p><p><b>METHODS</b>Eighty-six carotid arteries in 43 cases were examined with intracavitary convex array probe, low-frequency convex array probe and high-frequency linear probe to collect the data including the ICA visible length, peak systolic velocity (PSV), internal diameter, blood vessel shape; common carotid artery (CCA) intimae-medial thickness (IMT), PSV, and internal diameter.</p><p><b>RESULTS</b>Significant differences were noted in the visible length, PSV of ICA, and internal diameter detected by different frequency ultrasound probes. Intracavitary probe and high-frequency probe produced significantly different findings of the blood vessel shape.</p><p><b>CONCLUSION</b>Intracavitary convex array probe has important clinical value in detecting of ICA disease.</p>
