Clinician’s guide to the basic principles of MRI
Syifa Azhar, Le Roy Chong
Abstract
MRI is an important and widely used imaging modality for clinical diagnosis. This article provides a concise discussion of the basic principles of MRI physics for non-radiology clinicians, with a general explanation of the fundamentals of signal generation and image contrast mechanisms. Common pulse sequences, tissue suppression techniques and use of gadolinium contrast with relevant clinical applications are presented. Knowledge of these concepts would provide an appreciation of how MR images are acquired and interpreted to facilitate interdisciplinary understanding between radiologists and referring clinicians.
