This document provides guidance on MRI and CT scan protocols for various neurosurgical conditions including brain tumors, spine tumors, acoustic neuromas, trigeminal neuralgia, pituitary tumors, skull base tumors, nasopharyngeal carcinoma, AVMs, orbital tumors, paragangliomas, brachial plexus lesions, and pelvic conditions. It specifies the regions to cover, sequences, slice thickness, and other imaging parameters depending on the location and characteristics of the condition being imaged.
