[An intracavitary convex array probe for detecting internal carotid artery disease].
OBJECTIVE
To assess the value of an intracavitary convex array probe in detecting internal carotid artery (ICA) disease.


METHODS
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.


RESULTS
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.


CONCLUSIONS
Intracavitary convex array probe has important clinical value in detecting of ICA disease.
