Transcatheter CT hepatic arteriography-guided percutaneous ablation to treat ablation site recurrences of colorectal liver metastases: the incomplete ring sign.


Transcatheter computed tomography (CT) arterial portography-guided percutaneous liver tumor ablation has been proved to be feasible and accurate in treating liver metastases from colorectal origin that are obscure on ultrasound and unenhanced CT.
