Definition

MRI is the computer-generated cross-sectional images of the body obtained using a large static magnetic field gradient pulse to allow the resonance of hydrogen to be detected.

Current Knowledge

MRI became available in the early 1980s and developed into a method comparable to existing techniques, such as ultrasound and computed tomography (CT). MRI, however, is a more sensitive technique to detect pathology than X-ray attenuation. As the bone has a very low signal on MRI, extracerebral blood collections and pathology in the posterior fossa, inferior frontal, and temporal regions are better detected. Furthermore, imaging can be conducted in all three planes without requiring patient repositioning, and the better contrast between gray and white matter reveals anatomic details more readily, i.e., sulci can be seen even if they are compressed by extradural collections.

MRI has a clear advantage in characterizing lesions of all types in the subacute and chronic...
