MRI helps home in on disabilities caused by MS
Abnormalities throughout the spinal cord and the number of segments affected by spinal cord lesions are the most significant MRI parameters for characterizing physical disabilities caused by multiple sclerosis (MS), according to a study published in the November issue of Radiology.

DWI-MRI matches PET/CT in lymph node evaluation
Wednesday, December 4 | 3:10 p.m. - 3:20 p.m. | SSM17-02 | Room S505ABDiffusion-weighted MRI (DWI-MRI) is a viable, radiation-free alternative for evaluating lymph nodes, with findings that closely parallel those of FDG-PET/CT, researchers in India have concluded.

FDG-PET/CT tops MRI in colon cancer staging
Wednesday, December 4 | 3:00 p.m.-3:10 p.m. | SSM17-01 | Room S505ABWhile whole-body MRI is a feasible method for staging colon cancer patients, the modality does not quite reach the accuracy of FDG-PET/CT, according to a new study by Italian researchers.
