ABSTRACT
Objective To observe the change of MR perfusion value in patients with hepatocellular carcinoma (HCC) before and after transcatheter arterial chemoembolization (TACE). Methods A total of 22 patients with HCC underwent MR perfusion weighted imaging (MR PWI) before TACE and 3-10 days after TACE. The mean time to enhance (MTE), negative enhancement integral (NEI), time to peak (TTP) and maximum slope of decrease (MSD) before and after TACE were acquired and compared. Results The time intension curve (TIC) of HCC region was observed to descend rapidly before TACE, while descended slowly after TACE. The value of MTE and TTP after TACE were lower than those before TACE (P0.05). Conclusion MR PWI is a very sensitive imaging technique that be used to monitor blood flow changes of HCC before and after TACE and evaluate efficacy of TACE.
