Title: The Comparative Analysis of RA and LTLRA Applied to Detect Liver Carcinoma Lesion
Abstract: Objective To compare the sensitivity of abdominal DSA routine angiography(RA) and long time low rate angiography(LTLRA) applied to detect the liver carcinoma lesion, and to discuss the angiography feature of liver carcinoma lesion.Materials and Methods 220 cases with liver carcinoma were performed double parameters angiography (RA and LTLRA) of hepatic artery. The angiography images were evaluated after interventional operation. The sum and size of detected lesions were measured and statistic analysis on DSA images was done.Results In 220 cases, 562 lesions were detected by means of RA and the minimal diameter of lesion was 0.8cm. 691 lesions were identified by means of LTLRA and the minimal diameter of lesion was 0.3cm. The sum of lesion detected by means of RA and LTLRA were same in 140 cases. There was difference on the lesion's amounts and coloration in 80 cases. The data were analyzed statistically by χ2 test (P0.05). There was significant difference on the sensitivity of detecting lesion between RA and LTLRA.Conclusion LTLRA could comparatively increase the lesion's detecting ratio and especially present more sensitive to the lesions with poor blood supply and small size. However, RA was more useful to detect the lesion with rich blood supply. The combination of RA and LTLRA could remarkably upgraded the detecting ratio of lesion, so the double parameter angiography of hepatic artery would become the routine examination during liver TACE.
