I'd like to learn more about the different types of MRIs.

The most common type of MRI is a T1-weighted scan, which uses magnetic fields to generate images of the brain's anatomy. This type of MRI provides good contrast between white matter and gray matter, allowing for detailed analysis of the structure and function of the brain. A T2-weighted scan, on the other hand, produces images with better contrast between fluid and tissue. This makes it possible to identify certain conditions such as tumors or stroke, as well as to study the effects of trauma or disease in the brain. Additionally, diffusion tensor imaging (DTI) can be used to assess fiber tracts within the brain and measure their integrity.
