Abstract

SUMMARY

Objective: To study the role of 320 detector row CT in myocardial perfusion evaluation.
Material and Methods: A prospective and descriptive study was carried out on 12 patient with moderate or highly moderate risk of coronary artery diseases from December 2018 to May 2019 at Central Military Hospital 108.
Results: 10 male and 2 female, the average age was 63,2. 91.7% of the patients had myocardial ischemia with tranmural perfusion ratio (TPR)
≤ 0,99. The number of coronary arteries had perfusion abnormalities accounted for 38.9%. The diagnostic accuracy increased after perfusion
analysis with sensitivity from 83.3% to 91.7% and specificity from 75.0% to 91.7%.
Conclusion: 320 detector row CT is an effective method to perform both coronary CT angiography and CT perfusion imaging in the same examination . Now we are continuing to collect and study on more patients.
