Cardiovasc Intervent Radiol. 2022 Nov;45(11):1651-1658. doi: 10.1007/s00270-022-03157-4. Epub 2022 May 20.

Abstract

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.

Keywords: Hybrid angiography-CT; Radioembolisation; Selective internal radiation therapy; Yttrium-90 dosimetry.
