Purpose: To evaluate the role of Dynamic MRI and Diffusion-weighted magnetic resonance imaging to evaluate result of treatment hepatocellular carcinoma (HCC) after transcatheter oily chemoembolization (TOCE). Materials and Methods: A study from June 2011 to August 2012 at Bach Mai Radiology Department, consisting of 72 patients HCC after TOCE. Patients were examined with MRI (18 patients), CT (30 patients), CT and MRI (24 patients), DSA all patients. Describing lesions on Dynamic MRI, diffusion and ADC. Comparing MRI with DSA and CT, to evaluate the role ot MRI in examining HCC after TOCE. Results: Characteristic ot MRI after treatment TOCE hepatocellular carcinoma: 71.4 percent hyperintense on T2W, hypointense on T1W in-phase (73.8 percent) and T1W out-ot-phase (81.0 percent). After gadolinium injection, most ot tumor had hypervascular, enhancement in arterial phase, elimination in venous phase and delay phase. Hyperintense (diffuse restriction) on Diffusion. On ADC map, necrotic tumor tissue 1.827 x 10 exponent 2 mm2/s (95 percent CI: 1.728 - 2.181), viable tissue 1.116 x 10 mm2/s (95 percent CI: 1.021 - 1.307). MRI examined hypervascular ot tumor after TOCE and metastases better than CT scanner, with 24 patients were examined MRI and CT scanner, CT scanner assess hypervascular after TOCE difficulty. DSA was seen the gold standard to assess tumor hypervascular, accord between MRI and DSA in examination hypervascular ot tumor was 100 percent. Conclusion: MRI was a good technique to assess condition tumor after TOCE and discover metastases in HCC patient, hypervascular imaging accord with DSA 100 percent.
