Gradient-Magnitude and MR
← Gradient-Magnitude Comparison | ● | Multi-Dimensional Transfer Functions →
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!
