In the past decade,a variety of interventional procedureshave been employed for local control of hepatocellularcarcinoma(HCC).These include transcather arterialchemoembolization(TACE)and several tumour ablationtechniques,such as percutaneous ethanol injection(PEI),radio-frequency ablation(RFA),or percutaneous microwavecoagulation therapy(PMC),laser-induced interstitialthermotherapy(LITT),etc.For a definite assessment ofthe therapeutic efficacy of interventional procedures,histological examination using percutaneous needle biopsymay be the most definite assessment of the therapeuticefficacy of interventional therapy,however,it is invasiveand the specimen retrieved does not always represent theentire lesion owing to sampling errors.Therefore,computedtornography(CT)and magnetic resonance imaging(MRI)playa crucial role in follow-up of HCC treated by interventionalprocedures,by which the local treatment efficacy,recurrentdisease and some of therapy-induced complications areevaluated.Contrast enhanced axial imaging(CT or MRimaging)may be the most sensitive test for assessing thetherapeutic efficacy.The goal of the review was to describethe value of CT and MRI in the evaluation of interventionaltreatments.
