Effect of Magnetic Resonance Myelography on the Target Volume in Craniospinal Irradiation in Children

Implementation of coronal MRM during the treatment planning will improve target definition and lead to a more conformal field. Planning systems with the ability to fuse MRM with reconstructed coronal computed tomography are highly desirable. The use of MRI is highly recommended to individualise the lower border of the spinal field in craniospinal irradiation.
