Objective To discuss the role of EPI-DWI unite ASSET in the detection of hepatic colorectal micrometastasis. Methods 29 patients with hepatic colorectal metastasis were examined with EPI-DWI unite ASSET and EPI-DWI. Results In a lesion detection analysis,the overall detection rate was 93% (58/63) for ASSET-EPI-DWI,and 81% (51/63) for diffusion-weighted MR imaging. ASSET and EPI-DWI was more sensitive than diffusion-weighted MR imaging(P = 0.01 1). Conclusion ASSET-EPI-DWI is superior to diffusion-weighted MR imaging in the detection of hepatic colorectal micrometastasis.
