What to Read:    

  • MR Abdomen/Pelvis 
  • With Dr. Kagen only:
    • Surgical planning for tram flaps
    • Lymphedema studies
  • Inpatients cases should be read first
  • Leave Dr. Kagen’s MRA’s unless otherwise instructed (let Dr. Kagen protocol these cases)
  • Resident can/should prelim, especially when Dr. Kagen is on site
End of rotation presentation: Residents are expected to give a short 20-30 minute talk on a body MRI topic of choice.


Residents should protocol 1 week ahead of time. If there is no resident on MR, the attending will arrive by 9 am and protocol studies.
  • Senior resident protocols all sites in IDX. 
    • When junior resident is more experienced on the rotation, they should begin to protocol too
  • If you do not know the right protocol, ask or leave it blank. Guessing is not acceptable
  • If the script is not available and there is any question, write “Call radiologist with script”
  • If study is obvious (ie Prostate, Enterography) then leave it blank.

LIVER - Fat assessment

1.5T Fat Fraction (IDEAL IQ sequence) 
  • Put ROI on Liver in FatFrac IDEAL IQ sequence, get Avg Fat %
    • < 5: Normal 
    • 5-33: Mild 
    • 33-66: Moderate 
    • > 66: Severe 
Fat Fraction (In/Out of Phase)
  • IN – OUT x 100

LIVER - Iron assessment

Columbia University calculator

Iron Deposition Calculations:

1.       Put ROI on Liver in R2* sequence, get Avg R2*

2.       Use Avg R2* to calculate T2* = (1/R2*) x 1000

3.       In 1.5 T magnet:

a.       T2*< 21 ms means mild iron deposition

b.      T2*< 14 ms means severe iron deposition

4.       Go to and put T2* value to get Liver Iron Concentration mg/g (Normal Range: 0.17-1.8)

  • < 50: Normal 
  • > 71: Severe 
  • <14: Severe 
  • 14-20: Mild-Moderate 
3T Iron T2* 
  • < 14: Significant iron present 

LIVER - OPTN classification

Table 3 describes the mandatory diagnostic criteria for HCC classification in patients with chronic liver disease 

UNOS/OPTN system 
  • Standardizes the language that radiology reports must include to qualify for exception points 
  • Hepatic nodules must be classified according to OPTN criteria 
  • Nodules < 1 cm are too small to characterized and are NOT considered for additional priority on the transplant waiting list 
  • All HCC are categorized as class 5 lesions 
  • Non-diagnostic study is class 0 (images not of sufficient quality to confidently apply the criteria) à repeat study with same or alternative acceptable modality


  • Likert scoring criteria
