相对于公认的标准,多层螺旋CT(MDCT)心肌灌注诊断尚未得到确认。我们创建了一项MDCT影像心肌灌注定量技术,并参照SPECT心肌灌注成像(MPI)对其诊断价值进行了研究。98例病人被纳入研究。通过与对照组20例心脏分段的正常X线密度对照,检出异常灌注。
Relative to accepted standards, multi-slice spiral CT (MDCT) myocardial perfusion diagnosis has not yet been confirmed. We created a quantitative myocardial perfusion technique for MDCT imaging and evaluated its diagnostic value using SPECT myocardial perfusion imaging (MPI). 98 patients were included in the study. Abnormal perfusion was detected by normal X-ray density contrast with 20 segments of heart in control group.
