Abstract：Objective To explore the diagnostic value of ultrasonography (US) and multi-slice spiral
computed tomography angiography (MSCTA) in the evaluation of carotid plaque ulceration. Methods
A total of 400 patients underwent CDFI and MSCTA examination during 2010 and 2014 were analyzed.
The incidence rate of ulceration was compared. The carotid artery narrowing degree was observed. The
positional distribution and composition of the carotid plaque, as well as the correlation between plaque
ulceration in carotid arteries and the symptoms of cerebral ischemia, were studied. Results US and
MSCTA respectively detected 85 and 142 plaques, the difference of plaque ulceration detection rates
between US and MSCTA was statistically significant (P<0.05). US and MSCTA respectively detected
707 and 719 plaques without ulceration, the difference of non-ulcerous plaque detection rate between
US and MSCTA was not statistically significant. Ultrasound and MSCTA has a good consistency for the
evaluation of carotid artery stenosis (mild, moderate, and severe) and was not statistically significant
(P＞0.05). The plaque ulceration detection rates of the two methods in the examination of the three
positional distribution have statistical difference (P<0.01)．Plaque ulceration was statistically associated
with symptomatic ischemic events (P<0.05). Conclusion Plaque ulceration is a risk factor of the
development of cerebral ischemia. MSCTA can display carotid plaque ulceration more clearly than US.
US can be used as the first choice of the carotid artery imaging, whereas MSCTA should be followed if
vascular lesion found with US.
