2023年4月2日 · Knowledge of MRI physics is essential to the appropriate interpretation of MRI images. Due to excess demand and also wide availability of MRI, MR studies are frequently reviewed even by clinicians. Hence a sound knowledge of MR physics is essential for both radiologists and clinicians for adequate interpretation of MRI images.
MRI. Basic Principle of MRI. The hydrogen (1^H) atom inside body possess “spin” In the absence of external magnetic field, the spin directions of all atoms are random and cancel each other. When placed in an external magnetic field, the spins align with the external field.
