In radiotherapy, CT/MR images are used to delineate the region of targets and normal structures. In this study, 3D_NerveVIEW sequence was performed on a volunteer, and then the image of cranial nerve was rigidly registered and fused to CT image. In the fused image, the cranial nerve had better visualization than CT and T1w images, and the contour of nerve was easily identified. Which could improve the accuracy of nerve contour and reduce the radiotherapy-induced nerve palsy.
