摘要:
目的 评价多排探测器螺旋CT(multi-detect row computed tomography MDCT)冠状动脉造影结合超声心动图对冠心病的诊断价值。 材料方法 收集2002年-2003年间54例临床怀疑或确诊的冠心病患者。所有患者进行MDCT(美国GE公司四排探测器螺旋CT)冠状动脉造影及超声心动(美国惠普公司5500超声)检查,其中30例患者在CT和超声检查前后2周范围内进行了选择冠状动脉血管造影检查(selected coronary angiography SCA),并以此为金标准,对MDCTA结合超声心动图诊断冠心病的价值进行评估。 结果 54例患者中,42例患者显示56支冠状动脉病变;超声心动发现左室舒张功能障碍24例。30例SCA显示25例患者38支冠状动脉病变(左冠32支,右冠6支)。MDCT冠脉造影结合超声心动法与SCA法检查结果一致性为:92.86%,X2检验:X2=0.5;0.5>P>0.25,无显著性差异。 结论 MDCT冠脉造影扫描可以作为冠状动脉狭窄性冠心病的初步筛选手段,结合超声心动图有利于提高诊断准确性。
Abstract:
Objective To evaluate the diagnostic value of multi-detector row computed tomography (MDCT) angiography combined with Ultrasound for coronary heart disease. Methods 54 patients with clinical suspected or confirmed coronary heart disease were studied in 2002-2003. All the patients were performed with MDCT (GE, four row scanners) and Ultrasound (Hp 5500). Among them, 30 cases were performed selected conventional angiography (SCA) of coronary artery during two weeks period of MDCT and Ultrasound examination. As a golden standard, SCA results were used to evaluate the value of the combined MDCT and Ultrasound examination. Results: 42 of 54 patients were found a coronary stenosis (56 segments) in MDCT and 24 patients among them shows a diastole dysfunction of left ventricle in Ultrasound. 25/30 cases SCA shows 38 coronary artery stenosis (right 32, left 6). The consistence rate of diagnostic results between MDCT angiography and Ultrasound with SCA is 98.26%, X2 test: X2 =0.5, 0.5>P>0.25, no significant difference. Conclusion: MDCT coronary angiography can be used as a screen method to detect the coronary heart disease. It is helpful to improve the diagnostic accuracy if combined with Ultrasound.
