영문 초록

Purpose Transcatheter arterial chemoembolization(TACE) have a treating objective by inserting the angiography catheter in the hepatic artery that supplies blood to the hepatocellular carcinoma(HCC) and by this it can mix up the injection of carcinostatis and embolus substances to necrosis the liver cancer organisms. Typically a computed tomography(CT) decoding result was used as a treating plan by the doctor before transcatheter arterial chemoembolization was preceded but because of false classifications and the increased time of surgical operations, the anti-cancer medicine can be used in places that are not needed which bring out great pains to the patients. This investigation has been made so that confusions can be decreased when using the vascular volume rendering data that has been created in the 3 dimensional-lab. Materials and methods From a total of 1,144 cases that has used TACE at the National Cancer Center from June 1st, 2008 to August 5th, 2009, 50 HCC patients(43 men, 7 women with the average age being 58.18 years old ranging from 34 to 78 years) that converted their examined liver dynamic computed tomography’s artery phase image to a volume rendering image were evaluated by two decoding doctors and one radiologic technologist. Results The investigated patients were classified into four types. Type 1 was decoded that there was each lesion in the segment 5 through the segment 8 of the right lobe of liver according to CT test, but there was a lesion in other segment in case of TACE procedure. In other words, it meant that the segmentation was different in the right volume of liver. Type 2 was decoded that there was a lesion in the segment 4 according to CT test, but there was a lesion in the segment 8 in case of TACE procedure. In other words, is meant that the segmentation was different in the liver dome. Type 3 was decoded mat there was a lesion in me multiple segments or the single segment according to CT test, but there was a lesion in the single segment or the multiple segments in case of TACE procedure. And type 4 was the case that the results of decoding cannot be same or different in CT test and TACE procedure. Conclusion The hepatic artery’s shape in anterio-posterior conditions and the hepatic artery in right anterio-oblique Md left anterio-oblique conditions showed a significant difference. The blood vessels that seemed to be reiterated in AP conditions could be clearly classified by the change of angles in the right anterio-oblique and left anterio-oblique.
