Radioembolisation is an established transarterial therapy for hepatocellular carcinoma and liver metastasis. Success of radioembolisation depends on meticulous angiography and accurate dosimetry. Intra-procedure catheter-directed CT-angiography is commonly performed to improve the efficacy and safety of radioembolisation. This review article will (1) introduce the differences between cone beam CT and hybrid angiography-CT, and (2) describe the benefits of catheter-directed CT-angiography in radioembolisation from both an interventional radiology and nuclear medicine perspective.
放射性栓塞是一种成熟的经动脉治疗肝癌和肝转移的方法。放射性栓塞的成功取决于精细的血管造影和准确的剂量学。术中导管定向 CT 血管造影常用于提高放射性栓塞的疗效和安全性。本文综述（1）介绍锥形束 CT 和杂交血管造影-CT 的区别，（2）从介入放射学和核医学的角度描述导管定向 CT 血管造影在放射性栓塞中的益处。
