Purpose. To compare the number of image acquisitions and procedural time required for transarterial chemoembolization (TACE) with and without tumor-feeder detection software in cases of hepatocellular carcinoma (HCC). Materials and Methods. We retrospectively reviewed 50 cases involving software-assisted TACE (September 2011-February 2013) and 84 cases involving TACE without software assistance (January 2010-August 2011). We compared the number of image acquisitions, the overall procedural time, and the therapeutic efficacy in both groups. Results. Angiography acquisition per session reduced from 6.6 times to 4.6 times with software assistance (P < 0.001). Total image acquisition significantly decreased from 10.4 times to 8.7 times with software usage (P = 0.004). The mean procedural time required for a single session with software-assisted TACE (103 min) was significantly lower than that for a session without software (116 min, P = 0.021). For TACE with and without software usage, the complete (68% versus 63%, resp.) and objective (78% versus 80%, resp.) response rates did not differ significantly. Conclusion. In comparison with software-unassisted TACE, automated feeder-vessel detection software-assisted TACE for HCC involved fewer image acquisitions and could be completed faster while maintaining a comparable treatment response.
目的。比较在肝细胞癌（HCC）病例中，使用和不使用肿瘤供血动脉检测软件进行经动脉化疗栓塞术（TACE）时的图像采集次数和操作时间。材料与方法。我们回顾性分析了50例使用软件辅助TACE的病例（2011年9月至2013年2月）和84例未使用软件辅助TACE的病例（2010年1月至2011年8月）。我们比较了两组的图像采集次数、总操作时间和治疗效果。结果。在软件辅助下，每次血管造影采集次数从6.6次减少到4.6次（P < 0.001）。使用软件后，总图像采集次数从10.4次显著减少到8.7次（P = 0.004）。软件辅助TACE单次操作所需的平均操作时间（103分钟）显著低于未使用软件的单次操作时间（116分钟，P = 0.021）。对于使用和未使用软件的TACE，完全缓解率（分别为68%和63%）和客观缓解率（分别为78%和80%）差异不显著。结论。与未使用软件辅助的TACE相比，用于HCC的自动供血动脉检测软件辅助TACE涉及的图像采集次数更少，能够更快完成，同时保持相当的治疗反应。
