MR Liver Iron (Fe) Quantification WO BODY Protocol
Scan Notes
Last updated: 1/31/2024
Charge as: Abdomen WO
Scanner preference: MR2 or CHH2 only
Coil: Torso Coil
- No cardiac images to be acquired. ONLY LIVER images, please.
- Liver quantification consists of 3 sets of data, each sampling a different part of liver (dome, mid liver, inferior liver)
- The Fe sequences were created using a cardiac sequence, so you may have to put cardiac gating (either PPU or ECG) on the patient in order for proper gating.
- 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.
