MR perfusion images to discriminate between normal rectal wall and rectal cancers with less variance of perfusion values and superior image quality compared to conventional TWIST-Angiography can be generated using time-resolved free-breathing MRI with continuous golden-angle radial sampling and iterative reconstruction (GRASP). Additional morphologic assessment (“one-stop-shop”) with high spatial resolution, artifact-insensitive, multiphase, contrast-enhanced imaging may increase accuracy and diagnostic confidence of the examination.
