螺旋ＣＴ血管造影 (ＳＣＴＡ)是螺旋ＣＴ在应用方面最重要的进展 ,在大血管病变诊断中 ,ＳＣＴＡ有望取代有创伤性的常规血管造影。由于ＳＣＴＡ在多数血管病变的应用需进行二维和三维重建 ,ＳＣＴＡ技术参数的选择非常重要 ,直接影响到图像质量和解剖细节的显示。笔者通过 10
Spiral CT angiography (SCTA) is the most important application of spiral CT in the diagnosis of major vascular lesions, SCTA is expected to replace traumatic conventional angiography. Because SCTA is required for 2D and 3D reconstruction of most vascular diseases, the choice of SCTA technique parameters is very important and directly affects the display of image quality and anatomic detail.
