DWI plays an important role in detecting and characterizing liver lesions or tumors. There are three kinds of liver DWI acquisitions are commonly used in hepatic DWI: breath-hold , respiratory-triggered，free-breathing. This work compares the advantages and disadvantages of diagnosing focal liver lesions, to find the best acquisition sequence for different situations.
