In this proof-of-concept study, our aim was to determine an optimal minimum number of MRI sequences which allow confident characterization of liver lesions into benign versus malignant categories with reasonable accuracy. We hypothesized that an abbreviated liver MRI protocol including single shot T2-weighted, pre and dynamic post-contrast T1-weighted images has the potential to reduce overall scan time and throughput. If this can be performed without significant loss in diagnostic accuracy it may improve efficacy and be beneficial to current practice.
