Summary
Adrenal MRI protocol
Indications
This protocol is most frequently used to characterize incidentally detected adrenal masses (incidentalomas) found on other imaging modalities.
Preparation
IV contrast agent: None used routinely. If radiologist chooses to administer contrast, use 1 mmol/kg gadopentetate dimeglumine at 2 cc/s
Oral contrast agent: None
At completion of exam, page radiologist to check if intravenous contrast is necessary
Give patient 2 L nasal oxygen
Continue axial single-shot fast-spin echo FS to level of bladder
Exam sequences
(1) Coronal T1 spoiled gradient echo BH – Anatomic overview. Assess for adrenal mass. Be certain that “adrenal” masses are really in the adrenal gland.
(2–3) Axial T1 in and out of phase (IP/OOP) – Assess for intracellular lipid (microscopic fat) within adrenal lesions. This is by far the most important sequence for the adrenal gland.
(4) Axial T2 single-shot fast-spin echo – Identify T2-bright lesions within the adrenal glands.
(5) Axial T2 single-shot fast-spin echo FS – Compare to prior sequence to identify macroscopic fat.
(6) Radiologist check for contrast. If contrast is to be used run:
(7) Volume-interpolated gradient echo BH pre.
(8) Volume-interpolated gradient echo BH post 20 seconds.
(9) Volume-interpolated gradient echo BH post 1 minute.
(10) Volume-interpolated gradient echo BH post 2 minutes.
