C臂CT在钇-90微球放射栓塞治疗肝脏恶性肿瘤中的应用

The application of cone beam CT in performing Yttrium-90 microspheres radioembolization for hepatic malignancies

C臂CT广泛应用于钇-90(^(90)Y)微球放射栓塞治疗肝脏恶性肿瘤的手术过程中,具有以下作用:(1)有效提高对肿瘤病灶和肿瘤供血动脉的识别率;(2)有效地提高对高风险动脉和高风险吻合的识别率,从而降低异位栓塞的风险;(3)计算靶肝体积,协助计算^(90)Y的使用剂量。在术前选择性动脉造影、预防性栓塞和^(90)Y微球放射栓塞治疗肝脏恶性肿瘤的过程中,C臂CT可以作为其他影像学检查的有效辅助工具,进一步提高^(90)Y微球放射栓塞治疗肝脏恶性肿瘤的安全性。

Cone beam computed tomography(CT) has been widely used in performing yttrium-90(^(90)Y) microspheres radioembolization for hepatic malignancies.Cone beam CT has the following functions:(1) it can effectively improve the diagnostic accuracy of tumor lesions and demonstrate tumor-feeding arteries,(2) it can effectively improve the diagnosis rate of high-risk artery and high-risk anastomosis,thus reducing the risk of ectopic embolism events,and(3) it can calculate target liver volume so as to assist in calculating the required dose of ^(90)Y microspheres.In performing preoperative selective angiography,prophylactic embolization and ^(90)Y microspheres radioembolization for hepatic malignancies,cone beam CT can be used as an effective auxiliary tool for other imaging examinations so as to further improve the safety of ^(90)Y microspheres radioembolization for liver malignant tumor.(J Intervent Radiol,2022,32:413-416)
