摘要
目的探讨64排螺旋CT冠状动脉造影的临床应用价值。方法对202例临床拟诊为冠心病患者行64排螺旋CT血管成像,对所有原始数据采用容积再现,最大密度投影,多平面重组,曲面重建进行图像后处理,显示冠状动脉主干及主要分支。结果心率<70次/min且较平稳时冠状动脉成像质量最佳,可较准确地显示冠状动脉通畅情况、冠状动脉斑块、狭窄程度及管壁病变。对于桥血管及支架植入是否通畅和有无再狭窄显示良好。结论64排螺旋CT血管造影安全、快捷、无创,对冠状动脉疾患的筛选、内支架术后疗效随访等有很大的临床应用价值。
Objective To study the clinical value of 64 slice CT coronary angiography. Methods 202 cases with suspercted coronary artery disease were examed with 64 slice CT coronary angiography. All the row data were reconstructed with volume rendering, maximum intesity projection, muhiplanar reconstructionand curved planar reconstruction to display the coronary artery and its branches. Results The cornary image quality was excellent with a heart rate of 〈70 beats per-minute. The cases of coronary artery patency,the coronary soft or fiberous plaques, the extent of coronary artery stenosis and changes in wall were accurately showed. Of the graft and stent patency, and whether or not display good in a narrow. Conclusion 64-slice spiral CT angiography is a safe, fast, non-invasive diagnostic methods. It has important clinical value in screening coronary artery disease and in post operational effectiveness of coronary stent implantiona and vascular bypass.
