The aim of this study was to assess the efficacy of CT angiography for steno-occlusive diseases before and after interventional procedures, focusing on the role of multiplanar reconstruction (MPR) and source images. 17 patients with 20 steno-occlusive lesions underwent CT angiography before and after interventional procedures. For each lesion, the percentage stenosis obtained on CT angiography was compared with that on conventional angiography. In addition, MPR and source images were evaluated for the presence of wall thickening and calcification before interventional procedures, and the presence of dissection and luminal shape after interventional procedures. These findings were compared with those of conventional angiography. Although the percentage stenosis depicted on CT angiography correlated well with that on conventional angiography, MPR and source images clearly demonstrated the effect of intervention and the residual stenosis. MPR and source images clearly depicted wall thickening, wall calcification, the presence of dissection and the luminal shape. CT angiography provides useful information before intervention, while MPR and source images are of value in evaluating arterial wall abnormalities and morphological changes associated with interventional procedures.
本研究的目的是评估CT血管造影在介入治疗前后对狭窄闭塞性疾病的疗效，重点关注多平面重建（MPR）和源图像的作用。17例患有20处狭窄闭塞性病变的患者在介入治疗前后接受了CT血管造影。对于每处病变，将CT血管造影获得的狭窄百分比与传统血管造影的结果进行比较。此外，在介入治疗前评估MPR和源图像上是否存在管壁增厚和钙化，在介入治疗后评估是否存在夹层和管腔形态。将这些结果与传统血管造影的结果进行比较。虽然CT血管造影显示的狭窄百分比与传统血管造影的结果相关性良好，但MPR和源图像清楚地显示了介入治疗的效果和残余狭窄。MPR和源图像清楚地描绘了管壁增厚、管壁钙化、夹层的存在和管腔形态。CT血管造影在介入治疗前提供有用信息，而MPR和源图像在评估与介入治疗相关的动脉壁异常和形态变化方面具有价值。
