Magnetic resonance imaging in multiple sclerosis: A review of the basic principles and practical guidelines

Magnetic resonance imaging (MRI) represents an in-vivo window of the pathophysiology of multiple sclerosis (MS) and has led us to consider it as a key tool for diagnosis, management and decision-making when starting or changing disease modifying drugs (DMD). It is essential to be familiar with imaging techniques and recommended protocols that can improve activity detection in order to provide the best possible management^1-2. Many times there is a decoupling between clinicians and radiologists regarding the requirements requested when ordering an imaging study, which can translate into suboptimal management. This can happen due to poor communication, lack of knowledge of imaging techniques by clinicians, or, on the other hand, because radiologists are often unaware of the importance that specific characteristics of MRI may have in the neurologist's decision-making process. trafficker. Hence the importance of standardized MRI protocols for physicians and radiologists to become familiar with them, in order to improve image quality, lesion detection, and radiological reporting. This review summarizes the basic principles of MRI in MS and compares the relevant recommendations of the Consortium of MS (CMSC) and the European Consensus on Magnetic Resonance Imaging in MS (MAGNIMS); Presenting information in a simple and professional manner, easy to follow by experts and non-experts in the field.
