Clinical Necessity and Patient Selection in MR-Linac

Every new technology may not be best suited for a patient’s treatment, and a selection procedure is needed for the management plan. This is certainly the case with MR-Linac technology, which uses magnetic resonance (MR) images in real time to treat patients with a linear accelerator (Linac) on a single gantry. The complexity of this setup means that a lot of technical issues have to be addressed. It has been established that only about one-third of the cancer patient population may be suitable for MR-Linac. In this chapter, we will explore the clinical necessity of MR-Linac and examine the broad selection criteria that should be used for approving patient treatment.
