Report of Detection Rate of Cerebrovascular and Coronary Artery Disease Using 64-channel Multi-detector Computed Tomography (MDCT) on the Population Visiting Health Screening Center

Purpose To evaluate the detection rate of cerebrovascular and coronary artery disease (CAD), which were major cause of sudden death, on the population visiting health screening center using 64-channel multi-detector computed tomography (MDCT) and evaluate the usefulness of MDCT on health screening. Materials and methods 730 patients (M:F=531:199) were included in this study. Simultaneously, they underwent cerebral and coronary MDCT for health screening, MDCT was performed with 64-channel MDCT (Light Speed VCT, GE Health Care, USA) using 0.625mm of slice thickness and 0.35~0.5sec of tube rotation time. Data analysis was based on reading paper. We evaluated the detection rate of cerebrovascular disease including intracerebral aneurysm, steno-occlusive disease, brain tumor and coronary artery disease including presence of calcific plaque and stenotic luminal narrowing of coronary artery. Results The evaluated detection rate of cerebrovascular disease on health screening MDCT was 5.6% (41/730) including 34 patients (82.9%) with intracerebral aneurysm Among these, posterior communicating artery (P-com) aneurym was most commonly detected 18 patient (43.9%). In terms of corona1y artery disease, 217 paitents (29.7%) had calcific plaque and 47 patients (6.4%) had stenotic intravascular luminal narrowing of coronary artery. 14 of 217 patients (6.5%) had calcific plaque was classified into high(>400 calcium score) risk group of CAD. 19 of 47 patients (40.4%) had significant intravascular luminal narrowing was recommended coronary angiography for interventional treatment. Conclusion Cerebrovascular and coronary MDCT is expected to useful diagnostic tool for health screening because that can be used to classify the high risk group of cerebrovascular and coronary artery disease with sudden death potential.
