Shootout between MIP and GradMag as the employed techniques for the visualization of a breast tumor:

Syngo-Cedar-MIP vs. Syngo-Cedar-GradMag

The magnetic field of a MR machine principally is never perfectly homogeneous.

  • Hence, a MR image is often darker at the volume boundaries
  • or the same material is shown with different scalar values.

As a conclusion, we cannot regard MR values to have the same absolute preciseness compared to the observed Hounsfield units in CT images.

Therefore, gradient magnitude is the method of choice with MRI!
