多层螺旋CT无创冠状动脉成像的临床应用和进展

Current and Future Roles of Multi-slice Spiral Computed Tomography in Noninvasive Imaging of Coronary Arteries

多层螺旋CT(MSCT)的出现对心血管成像有重大影响,作为一种无创检查技术,MSCT不仅可用于评价冠状动脉狭窄和定性、定量检测冠状动脉斑块,还可用于分析心功能和心肌灌注,评价支架和桥血管的通畅性。近年来的研究显示,MSCT无创冠状动脉成像可作为一种有效的冠心病筛查手段,同时用于介入和手术治疗后的随访观察。

The emergence of multi-slice spiral computed tomography （MSCT） has a significant influence on cardiovascular imaging. As a noninvasive technique, MSCT is considered suitable for the evaluation of coronary artery stenosis, quantitative and qualitative assessment of plaque, analysis of cardiac function and myocardial perfusion imaging, and determination of the patency of stents or bypass grafts. Recent studies has shown that noninvasive coronary artery imaging with MSCT is a feasible screening test for suspected coronary artery diseases and a valuable follow-up tool for patients who have undergone interventional or surgical therapeutic procedures.
