IMAGING OF INTRA CRANIAL SPACE OCCUPYING LESIONS THROUGH MAGNETIC RESONANCE

Abstract

“Imaging of intracranial space occupying lesion has been given new depth with the advent of CT and MRI scanning, allowing for exquisite anatomical detail in the axial, sagittal, and coronal planes and allowing for the characterisation of tumour tissue. The development of MR angiography has allowed for the noninvasive creation of a three-dimensional virtual vascular map of tumour blood supply, which has aided in the early diagnosis and localization of the SOL and, in conjunction with cutting-edge neurosurgical techniques, has improved the prognosis of mass lesions.” ^[2]

“When combined with MR angiography, these techniques provide the neurosurgeon with a virtual road map that helps determine whether or not surgery is even possible, and how it should be approached if it is. ^[3] CT, on the other hand, is an easily accessible, cost-effective alternative. Acute bleeding, calcification, and bone degeneration are also improved.” ^[1]

“MRI is preferable to CT because it provides more information about the lesion, including whether it is diffuse or localised, if there is any remaining tumour or if it has returned, where many lesions are located, and how they relate to and affect the spinal column. MRI's other strengths—multi-planar imaging and MR angiography—make it a valuable diagnostic tool as well."
