双源 CT 血管成像在颈动脉体瘤术前评估中的价值

目的：探讨双源CT （DSCT ）血管成像在颈动脉体瘤术前评估中的价值。方法收集18例颈动脉体瘤患者行DSCT头颈部血管造影，通过多方位重建（MPR）、最大密度投影（MIP）和容积再现（VR）得到二维和三维重建图像。所有患者均同时做了彩色多普勒血管显像（CDFI）检查，并均经手术证实。结果 DSCT血管成像均能成功地检查所有患者，18例患者共检出18个颈动脉体瘤，所有患者均为单侧颈动脉体瘤，肿瘤直径最大为12 cm ，最小为1.2 cm ，所有患者的头颈血管、肿瘤的血管生成以及肿瘤与周围血管的关系均得以清楚显示。结论 DSC T血管成像是一种很有价值的可以准确显示颈动脉体瘤患者双侧的头颈血管的诊断手段，能为手术提供可靠的信息。

The value of dual source CT angiography in evaluation of carotid body tumor

Objective To study the value of dual source CT (DSCT ) vascular imaging in preoperative evaluation for carotid body tumor (CBT ) .Methods DSCT cerebral and carotid angiography was performed on eighteen patients with CBT .Two‐di‐mensional and three‐dimensional reconstruction images were obtained by means of multiple planar reconstructions (MPR) ,max‐imum intensity projection (MIP) and volume rendering (VR) .All patients were subjected to color Doppler flow imaging (CD‐FI) examination and confirmed by surgery .Results DSCT angiography was successful for all patients .CBTs were diagnosed in 18 patients with 18 lesions .The largest lesion was 12 cm in diameter ,and the smallest one was 1.2 cm in diameter .The head and neck vessels ,tumor angiogenesis ,and relationship between tumor and surrounding blood vessels of all patients were clearly demonstrated .Conclusion DSCT cerebral and carotid angiography can provide reliable information for the operation .It might be a valuable diagnostic method for CBT by showing accurate views of the CBT along with the bilateral neck and brain blood vessels .
