Synopsis

DWI is an important sequence for the diagnosis of liver lesions and to monitor the treatment response in patients undergoing therapies for hepatic malignancies [1]. But it is difficult to place the anterior abdomen coil for obese patients in non-wide bore MRI systems because of a potential chance of pinching the coil between patient and the bore. This is a limiting factor for the adoption of liver DWI MRI in clinical practice [2]. As a solution, we are proposing Dual Shots DWI with under-sampling across shots using volume coil located inside the magnet.
