Abstract

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.
