MR Adrenal Mass W/WO BODY Protocol
Scan notes:
- Send ADC maps
- Send Subtractions
- FOV: do not include patient’s arms
Breath Holds:
- Scan on expiration.
- Monitor that patient is breath-holding. Breathe the patient slowly so they have time to follow instructions. Do not start scan until the patient has stopped breathing.
- Give 2L O2 if it will help with breath-holds UNLESS PATIENT HAS COPD OR ANOTHER REASON NOT TO GIVE O2.

| Plane | Weighting | Mode | Slice | Gap | FAT SAT | FOV | Notes | |
|---|---|---|---|---|---|---|---|---|
| Cor | T2 | SSFSE BH | 5mm | 0.5mm | None | Diaphragm to Aortic bifurcation | Abdominal wall to abdominal wall | Ensure liver is well-centered in coil to ensure good signal at dome. |
| Axial | T1 | Dual Echo SPGR BH | 3mm | 0.5mm | None | Fit to Patient | Liver through upper pole of kidneys | Center over adrenals. Call rad if help is needed to locate adrenals. |
| Cor | T1 | Dual Echo SPGR BH | 3mm | 0.5mm | None | Diaphragm to Aortic bifurcation | Abdominal wall to abdominal wall | Center over adrenals. Call rad if help is needed to locate adrenals. |
| Axial | T1 | 3D mDixon pre BH | - | - | Yes | Fit to Patient | Diaphragm to Aortic bifurcation | Ensure quality before contrast injection, ie wrap. Check if there is mottling (SENSE break-through) in the center of the image. |
Contrast injection
Dose by weight. 2cc/sec with saline chaser. Bolus Track. Trigger when bolus reaches SMA.
| Plane | Weighting | Mode | Slice | Gap | FAT SAT | FOV | Notes | |
|---|---|---|---|---|---|---|---|---|
| Axial | T1 | 3D mDixon x3 phases BH | - | - | Yes | Fit to Patient | Diaphragm to Aortic bifurcation | Exact parameters as the pre-mDixon. Do all 3 phases (Arterial, Arterial/Venous, Delay) one right after another, as soon as the patient can hold their breath again. |
| COR | T1 | 3D mDixon post | - | - | Yes | Diaphragm to Aortic bifurcation | Abdominal wall to abdominal wall | Perform @ 3 minutes post contrast. |
| Axial | T2 | TSE FS | 5mm | 1mm | Yes | Fit to Patient | Diaphragm to Aortic bifurcation | |
| Axial | T2 | DWI | 7mm | 1mm | SPIR | Fit to Patient | Diaphragm to Aortic bifurcation | Trigger & track. Free-breathing sequence, so please position slices according |
