Abstract:
Objective To assess the value of MSCT in the follow-up of patients with small hepatocelluar carcinoma(sHCC) treated with RFA. Methods Twenty-eight patients with sHCC underwent MSCT scanning 1, 3 and 6 months after RFA. Results One month after RFA, 25 tumors were completely necrotized, among which 19 presented no enhancement on dual-phase contrast CT scans and 6 showed thin ring-shaped enhancement on artery-phase contrast. Three cases with residual tumor manifested as nodular enhancement in margin of lesion. Three and 6 months after RFA, all 25 tumors, which were completely necrotized, became small and presented no enhancement. New tumors were found in the liver in 2 cases six months after RFA. Conclusion RFA is an effective therapeutic method for sHCC, and MSCT dual-phase enhanced scanning is a good way for evaluating the curative effect and follow-up.
