Advances in the Application of Magnetic Resonance Imaging in the Diagnosis of Brain Diseases

Abstract

Magnetic resonance imaging is now a relatively mature technique, with a variety of sequences with different functions have derived from conventional magnetic resonance imaging, each with its own advantages in monitoring brain function, detecting oedema or infarction, identifying tumours and assessing prognosis. This paper will review the principles of functional magnetic resonance imaging, diffusion weighted imaging and perfusion weighted imaging and their applications in the diagnosis of brain diseases, with the aim of providing ideas for the selection of diagnostic methods for brain diseases, and put forward the further development direction of diagnostic technology
