Abstract:
Objective To discuss the applied value of diffusion weighted imaging(DWI) in evaluating emboliza-tion effect of transcatheterhepatic arterial chemoembolization(TACE) for Hepatic Metastases. Methods DWI was performed in 17 Hepatic Metastases patients at the next day after TACE. Embolization effect was analyzed andcompared with DSA results. Results 17 lesions were revealed in DSA anA with complete iodinated oil accumulation,9with incomplete accumulation. 47 lesions were revealed in DWI and 33 with complete iodi, a oilaccumulation,9 with in-complete accumulation,5 without iodinated oil accumulation.The area of iodinated oll accumulation and necrosis appeared aslow signal on DWI,and residual tumor tissues appeared as high signal. Conclusion DWI may detect Hepatic Metastases lesions sensitivelyand can be used to evaluate the embolization effect of TACE.
