Magnetic Resonance Imaging (MRI)

Magnetic Resonance Imaging (MRI) is a medical imaging technique that uses strong magnetic fields, magnetic field gradients, and radio waves to generate anatomical images.

Advantages

MRI has a clear advantage of no ionizing radiation. It also has an advantage over CT in that it can detect blood flow, occult/cryptic vascular malformations, and demyelinating diseases like multiple sclerosis. There are also no beam-hardening artifacts as seen in CT, and the posterior fossa is more easily visualized on MRI than CT.

Disadvantages

T1 Weighted

T2 Weighted

Fluid-Attenuated Inversion Recovery (FLAIR)

Functional (fMRI)

Diffusion Weighted Imaging (DWI)

Diffusion Tensor Imaging (DTI)
