MRE & R2*

Siemens Aera 1.5T ROIs display deca Pa.

Example: ROI in McKesson = 500. This is 5000 Pa or 5 kPa.

< 2.5 kPa - Normal

> 2.9 kPa - Increased liver stiffness suggesting fibrosis.

Report valules should be in kPa.

Normal R2*

Example: ROI on T2* map in McKesson = 25. This is 25 ms or 0.025 s, or 40 s^-1

1.5T - Less than 60 s^-1

3.0T - Less than 120 s^-1
