Inversion recovery (IR) techniques allow the suppression
of one particular species (e.g. CSF fluid or fat).
However, these techniques have their limitation. A
single inversion time (TI) has to be chosen
prospectively, resulting in only one contrast per IR
experiment. Here, we demonstrate that employing a radial
trajectory in combination with a conventional radial
reconstruction allows the reconstruction of several
images with different tissue types cancelled out of one
singleshot dataset. Thus, no fixed TI is necessary and
the desired contrasts can be chosen retrospectively,
what makes this technique a promising candidate for
clinical practice.
