Zhen J. Wang and Benjamin M. Yeh: Is Assessing Renal Oxygenation by Using Blood Oxygen Level–Dependent MR Imaging a Clinical Reality?
In combination with other techniques such as MR perfusion- and diffusion-weighted imaging, renal MR imaging is evolving from a primarily morphologic assessment to one that probes both form and function.

Once lesions with macroscopic fat have been excluded, pixel attenuation histogram analysis cannot be used to distinguish angiomyolipomas (AMLs) from clear cell renal cell carcinomas (CCRCCs); on the contrary, lower CT attenuation is more strongly associated with CCRCCs than with AMLs.
