Radiology Pearls

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.

MRI

• Nomenclature: use "intensity".

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.
• GRE: In phase/Out of phase. Most sensitive for assessing iron deposits, steatosis.
• T2-star:
• FLAIR: heavily T2-weighted image which suppresses CSF
