Abstract：Objective To study the 16 row spiral CT and 320 slice volume CT in detection and treatment of carotid atherosclerotic
plaque. Methods 58 patients with symptomatic carotid artery stenosis were selected from January 2016 to June 2016 in our hospital
as the research objects. All patients underwent digital angiography in CT reduction (DSA) examination and color Doppler ultrasound
of carotid artery (CDFI). All of the 58 patients were examined by 16 slice spiral CT and 320 slice CT. The difference of plaque
detection results between 16 slice spiral CT and 320 slice CT were compared. The results were also compared with the results of
CDFI and CT. The sensitivity and specificity of two kinds of CT assessment on the degree of artery stenosis and plaque lesion density
were analyzed. Results There was no significant difference on the detection rate between the 16 rows of CT and 320 slice volume
CT in detection of carotid atherosclerosis with P>0.05. When used DSA examination results as the gold standard, both the sensitivity
and specificity of 320 slice volume CT are slightly higher than that of 16 row CT in detection of more than 70% artery stenosis
(P>0.05). When used the CDFI diagnosis results as a standard, there were also no significant differences on both the sensitivity and
the specificity between 320 slice volume CT and 16 slice CT on the diagnosis of atherosclerotic plaque (P>0.05). Conclusion 16
slice spiral CT and 320 slice CT is sensitive, specific and accurate in the diagnosis of carotid artery stenosis. Its accurate assessment
of the degree of stenosis is beneficial for selection of interventional lesion materials and for evaluation of risk of emboli loss.
