目的前瞻性评估大螺距(HP)双源螺旋CT冠状动脉成像(CTCA)诊断冠状动脉明显狭窄的准确性,并与经导管冠状动脉血管造影(CCA)进行对照研究。方法35例病人[平均年龄(62±8)岁,其中7例女性]均进行了CTCA和CCA检查。CTCA应用的是螺距为3.4的第二代双源CT。心率60次/min以上的病人不纳入
Objective To prospectively evaluate the accuracy of dual-source helical CT coronary angiography (CTCA) in diagnosing significant stenosis of coronary arteries and compare it with that of transcatheter coronary angiography (CCA). Methods Thirty-five patients (mean age 62 ± 8 years, 7 of whom were women) underwent CTCA and CCA. CTCA uses a second generation dual-source CT with a pitch of 3.4. Patients with a heart rate of 60 beats / min or more are not included
