Good article.

For our purposes most imaging will be T2. Water is bright and fat is dark. The opposite occurs in T1 weighted imaging. (Easy way to remember it is T2 = H2O for water).

"T1 and T2" are slightly out of date in MRI, but oral surgeons love to hang on to old stuff for boards and pimping. Truth is that there are so many different MRI's with a myriad of different options...."T1 with fat suppression"...every time I talk to a radiologist about an MRI, they get upset when we try to figure out if it is T1 or 2. They look at you like you're about 15 years behind...but for boards sake the above way is a good way to remember if one accentuates fat or water.....
