Abstract
Background
Transarterial chemoembolization (TACE) is an important treatment modality for hepatocellular carcinoma (HCC). Accurate identification of feeding arteries and catheterization are necessary for achieving treatment efficacy, especially with selective TACE. However, this often requires multiple imaging studies. We evaluated the utility of a newly developed apparatus that combines multidetector-row computed tomography (MDCT) and angiography (angio-MDCT) to facilitate TACE for treatment of HCC.
Methods
A total of 73 patients who underwent selective TACE with angio-MDCT were compared with 57 patients who had undergone selective TACE with single-row computed tomography assisted by angiography (angio-CT) in terms of the number of imaging studies needed to complete TACE.
Results
The mean number of digital subtraction arteriography (DSA) and CT studies required for characterization of feeding arteries before embolization was 3.53 (range 1–8) and 5.16 (range 2–11), respectively, with single-row angio-CT, and 1.67 (range 1–5) and 2.90 (range 1–5), respectively, with angio-MDCT. Fewer studies were needed in patients who underwent TACE with angio-MDCT (p < 0.0001 for both DSA and CT). Whereas single-row angio-CT failed to identify extrahepatic feeders in three patients (37.5 %), all extrahepatic feeders could be identified with angio-MDCT.
Conclusions
Angio-MDCT facilitates rapid and accurate identification of feeding arteries in patients undergoing TACE through the three-dimensional image analyses by the reconstruction with the workstation.

Images of bone and organs were first removed from the original image (a, b), and the vascular image was extracted (c). Bone images were then added (d) to facilitate identification of the level of the origin of the feeding artery on the X-ray monitor

Fig. S3 Identification of the hepatocellular carcinoma (HCC) feeding artery based on three-dimensional (3D) vascular images from a combined 64-multidetector-row computed tomography (CT) and angiography (angio-MDCT) system. The HCC was located in the right lobe of the liver (a, b). It was difficult to identify the feeding artery on two-dimensional digital subtraction angiography (DSA) images (c) because of the lack of clear tumor staining. Analysis of 3D vascular images revealed that the feeding artery branched from left hepatic artery, which was far from the HCC (d). a CT during arterial portography, b CT during hepatic arteriography, c two-dimensional DSA, d 3D vascular image constructed from aortography using angio-MDCT

Fig. S4 Identification of the hepatocellular carcinoma (HCC) feeding artery using three-dimensional (3D) vascular images from a combined 64-multidetector-row computed tomography (CT) and angiography system. It was difficult to identify the feeding artery at its origin on two-dimensional digital subtraction angiography (DSA) images (a) or in the frontal view of the 3D vascular image (b) owing to overlap of arteries. Changing the orientation of the 3D vascular image (c) and changing the X-ray monitor view to the 3D vascular image (d) allows the identification and catheterization of the feeding artery. a DSA of the common hepatic artery, b 3D vascular image constructed from CT aortography (frontal view), c 3D vascular image constructed from CT aortography (right oblique view), d DSA of the proximal branch of the feeding artery (views with orientation adjusted on the basis of the 3D vascular image).
