Resources
- https://www.radiologyeducation.com (links to most of the major radiology websites and a lot of free resources)
- eAnatomy is an excellent tool for understanding MRIs. It’s $30 a year (if you have a free membership, unclear which membership).
- Radsource is another good resource.

Sequences
- T1: pancreas (due to Mn2+ deposition in the pancreas), fat, protein, hemorrhage, melanin, and gadolinium.
- T2: fluid (excluding blood)
- DWI: bright areas are suspicious for infarcts, but can also be T2 shine-through. Dating the chronicity of infarcts can be done with T1 and T2.
- ADC: dark areas on ADC are infarcts, and should correlate with bright areas on DWI.
- In phase/Out of phase: iron deposits, steatosis.
- T2-star:
- FLAIR:
- CSF-suppress:
