Cine phase-contrast magnetic resonance imaging can be used to noninvasively and safely assess renal perfusion during critical illness in man. Near-simultaneous accurate measurement of cardiac output enables organ blood flow to be assessed in the context of the global circulation. Renal blood flow seems consistently reduced as a fraction of cardiac output in established septic acute kidney injury. Cine phase-contrast magnetic resonance imaging may be a valuable tool to further investigate renal blood flow and the effects of therapies on renal blood flow in critical illness.

3D T2-weighted MRI has been increasingly utilized for pelvic applications, including imaging of rectal cancer, prostate cancer, anorectal fistulas and the female pelvis. This relatively rapid technique offers good soft-tissue contrast of the pelvic organs, with potential for more widespread clinical use.
