Overview
MRI may be used for diagnosing adrenal adenomas when the attenuation on CT is <30 HU.
MRI
- Chemical shift imaging on MRI is the most reliable for diagnosis especially when CT findings are unrewarding.
- MRI is useful for adrenal masses with a signal intensity <30 HU.
- Signal dropout on out-of-phase imaging for:
- 10-30 HU on CT is 89% sensitive and 100% specific
- 10-20 HU on CT is 100% sensitive and 100% specific
