This study presents an approach to retrospectively remove contrast agent
from the final images, denoted as "virtual non-contrast enhanced
imaging". Virtual non-contrast imaging can be performed by acquiring images with different flip angles and characterizing the individual signals.

4: In-vivo scans of patient one. Image acquired with a low flip angle of 5° (A)
and the corresponding VNC image (B). Image acquired with a high flip angle of
26° (C) and the corresponding VNC image (D). T1weighted image acquired after CA
injection (E), true non-contrast enhanced image (F).
