MR Liver Mass W/WO + Fe Quantification BODY Protocol

Scan Notes

Last updated: 1/31/2024
Charge as: Abdomen W/WO
Scanner preference: CHH or MR2 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.
Plane Weighting Mode Slice Gap FAT SAT FOV Notes
Cor T2 SSFSE 7mm 1mm None Liver through bottom of kidneys Breath Hold. Ensure liver is well-centered in coil to ensure good signal at dome.
Axial Liver Quantification (Dome) T2* FFE 10mm 10mm None One slice positioned at dome of liver. See images below Breath Hold
Axial Liver Quantification (Mid-Liver) T2* FFE 10mm 10mm None One slice positioned at mid-liver. See images below. Breath Hold
Axial Liver Quantification (Inferior liver/abd) T2* FFE 10mm 10mm None One slice positioned at lower portion of liver. See images below. Breath Hold
Axial T1 Dual Echo SPGR BH 5mm 0.5mm None Entire liver May be separated into overlapping stacks if patient cannot breath-hold. Do not interleave images. Okay to use 6mm slice thickness with 1mm gap on MR1 and CHMR2.
Axial T1 3D mDixon pre BH - - Yes Entire liver Ensure quality before contrast injection
Power Inject Contrast Bolus Track Trigger when bolus reaches the SMA
Axial T1 3D mDixon x3 phases BH - - Yes Entire liver Exact parameters as the pre-mDixon.
COR T1 3D mDixon 3 min post - - Yes Cover diaphragm to aortic bifurcation, abdominal wall to abdominal wall Perform @ 3 minutes post contrast
Axial T1 3D mDixon BH - - Yes Entire liver Timed exactly 4 mins post-injection.
Axial T2 TSE RT 5mm 0.5mm SPAIR Entire liver Okay to use 6mm slice thickness with 1mm gap on MR1 and CHMR2.
Axial T2 DWI 7mm 1mm Liver through bottom of kidneys
Axial T2 SSFSE RT 5mm 0.5mm Yes Entire liver Optional sequence if T2 SPAIR is poor quality. Okay to use 6mm slice thickness with 1mm gap on MR1 and CHMR2.
