title: Accurate and rapid identification of feeding arteries with multidetector-row angiography-assisted computed tomography for transarterial chemoembolization for hepatocellular carcinoma.
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.
