64层螺旋CT在冠状动脉造影中的应用

目的 探讨64层螺旋CT（MSCT）冠状动脉（简称冠脉）造影的临床应用价值。方法 对26例患者行64层MSCT冠脉造影检查，利用其先进的后处理功能对冠脉进行重组，以显示冠脉各主支及分支，并对冠脉病变进行诊断。对诊断冠脉不同程度狭窄的16例患者中15例行选择性血管造影检查。结果 26例行64层MSCT冠脉造影均成功地显示冠脉各主支（左冠脉主支、左冠脉回旋支、左冠脉前降支及右冠脉主支）及其分支（包括右冠脉的后降支、左室后支、圆锥支、窦房结动脉及左冠脉的对角支、钝缘支等），18例患者的56支冠脉有不同程度的硬斑块和软斑块，其中16例的38支冠脉伴有不同程度的狭窄，15例行选择性血管造影的患者显示32支冠脉有不同程度的狭窄。结论 64层MSCT是1种安全可靠的检查方法，其对冠脉疾病的诊断准确率较4～16层MSCT有明显提高。

The clinical application of 64-slices spiral CT in angiography of coronary artery

Objective To study the clinical application of 64-slices spiral CT in coronary artery. Methods Twenty-six patients were performed 64-slices spiral CT in coronary artery, 15 of the 26 patients underwent selective coronary artery angiography. Results The main branches and part of the sub-branches of the coronary artery were clearly displayed. 38 coronary artery branches of 16 patients were found stenosis. In 15 cases with conventional angiography, all main branches and parts of sub-branches of coronary artery were displayed clearly. All patients demonstrated coronary artery stenosis. The diagnostic accuracy of 64- slices spiral CT was 94.12%. Conclusion As a minimally invasive examination, 64-slices spiral CT is a valuable method to detect and diagnose the diseases of coronary artery.
