目的评价活动平板试验(TET)与64排双源螺旋CT(DSCT)诊断冠心病的准确性。方法对70例疑似冠心病的患者分别行TET、DSCT、冠状动脉造影(CAG)检查,以CAG为参照,评价TET、DSCT诊断冠心病的准确性。结果 TET和CAG在诊断冠状动脉的狭窄方面有明显差异(P<0.05);DSCT与CAG具有较好的相关性(P>0.05)。结论双源CT血管成像对冠心病诊断具有较高价值。
Objective To evaluate the accuracy of treadmill exercise test (TET) and 64-slice dual-source spiral CT (DSCT) in the diagnosis of coronary heart disease. Methods TET, DSCT and coronary angiography (CAG) were performed in 70 patients with suspected coronary artery disease. The accuracy of TET and DSCT in diagnosing coronary artery disease was evaluated by CAG. Results TET and CAG were significantly different in the diagnosis of coronary artery stenosis (P <0.05). There was a good correlation between DSCT and CAG (P> 0.05). Conclusion Dual-source CT angiography is of great value in the diagnosis of coronary heart disease.
