The Development of MR-Based, Online Adaptive Techniques for the Treatment of Liver Cancer

The use of curative radiotherapy (RT) in liver cancer has become increasingly feasible with new technical advances; our institution treats approx. 100 liver patients per year. One challenge in liver RT is accurately targeting the tumor while avoiding the surrounding normal liver and adjacent normal tissues. Liver motion during breathing also adds complexity to targeting lesions accurately. Unfortunately, the use of CBCT provides poor contrast for image guidance. With the advent of the MR-Linac, use of MR imaging prior to treatment delivery facilitates the potential to visualize the liver tumor and quantify breathing motion, thus permitting online treatment adaptation for each fraction.
