Road to RSNA 2015: MRI Preview
By Wayne Forrest
This installment of the Road to RSNA 2015 offers a preview to a plethora of studies that use different MRI techniques, as well as pair the modality with PET to further expand the technology's influence. Scientific papers scheduled for presentation in Chicago include studies on diffusion-weighted MRI to assess kidney disease, diffusion-tensor MRI for concussions, PET/MRI for breast cancer and other oncological applications, and many more topics.

FDG-PET/MRI bests DWI-MRI for lymphoma
By Wayne Forrest
Tuesday, December 1 | 11:20 a.m.-11:30 a.m. | SSG11-06 | Room S505ABIn another study led by Dr. Johannes Grueneisen from University Hospital Essen, researchers found that FDG-PET/MRI was better than diffusion-weighted MRI (DWI-MRI) alone for detecting malignant and benign lesions in lymphoma patients.
