ADVANCES IN MAGNETIC RESONANCE IN BRAIN TUMORS

Abstract

Space-occupying lesions in the central nervous system (CNS) constitute a major health problem and represent a challenge within the imaging field. Imaging methodology has a major role in the management of brain tumors. The modality that has been mostly used for this type of diagnosis is Magnetic Resonance Imaging (MR), to determine the severity of the lesions in these delicate areas. Currently, MRI is performed as a preoperative procedure, and when the patient is on the ward after surgery, the procedure is repeated to verify that the brain tumor has been removed. If after that, it is verified that said procedure has not been carried out, the operation is repeated but with the intraoperative resonance, in order to verify that while the operation is being carried out, the objective of the surgery has been reached and to rule out the presence of complications during this procedure. Among the challenges that are built when evaluating the diagnoses in this type of lesions, is to differentiate those intra-axial lesions of a non-invasive nature, in such a way that it can be planned postoperatively. When integrating the anatomical information provided by traditional MRI together with advanced techniques, it contributes to offering accurate and optimal information. Among these advanced techniques within MRI are perfusion imaging (PW-MRI), diffusion imaging (DW-MRI) and MR spectroscopy (MRS), among others. The objective of this study is to describe the advances in magnetic resonance imaging in the CNS areas, which has made it possible to show greater benefits for both surgeons and patients. For this purpose, a bibliographic documentary research will be carried out in the databases of scientific journals of the last ten years, with the purpose of describing the respective findings in this medical area.
