Abstract

To compare the diagnostic accuracy of 64-slice computed tomography and Doppler sonography in patients with cerebral
infarction caused by atherosclerotic plaques of carotid system.


Objectives: (1) Describing that cause image findings of 64-slice computed tomography and Doppler sonography in patients
with cerebral infarction caused by atherosclerotic plaques of carotid system. (2) Comparison image findings of 64-slice computed tomography and Doppler sonography in patients with cerebral infarction caused by atherosclerotic plaques of carotid system.
Method: we studied 34 patientswith the diagnosis of ischemic stroke admitted to Huu Nghi Hospital from 11/2013 to 9/2014. All patients’s carotid arterial system were evaluated by US and then by 64-slice CT.
Results: Average age: 76.5 ± 8.5. Hypertension: 80%. Diabetes: 37.1%. High blood cholesterol: 20%, previous stroke history: 45.7%. More than 2 Risk Factors: 60%. Carotid artery stenosis: Normal: 35.3% by 64 slice ct and 32.3% by Ultrasound. Up
to 69%: 47.2% by 64 slice ct and 44.3% by Ultrasound. 70-100%: 20% by 64 slice ct and 18.6% by Ultrasound. This study showed
almost perfect agreement between 64-slice computed tomography and Doppler sonography in detection of stenosis with kappa value of 0,804.
Conclusions: Good correlations were observed between 64 slice computed tomography and Doppler sonography in evaluating
carotid artery system in cerebral infarction caused by atherosclerotic plaques of carotid system.
