New MRI Algorithm Cuts Scan Time by Two-Thirds
A far quicker MRI scan is on the horizon. A new algorithm developed by MIT’s Research Laboratory of Electronics cuts the imaging time by two-thirds, though they’re still working on the back end processing time. Authors of the research, which is scheduled for publication in the journal Magnetic Resonance in Medicine, say that a 45-minute scan can be done in 15 minutes without compromising much of the quality.

MRI Technique Promises Easier Way to Diagnose Alzheimer’s Disease
Researchers just found what they said is a cheaper and safer way to diagnose and track Alzheimer’s disease, using arterial spin labeling (ASL), a magnetic resonance imaging (MRI) technique. University of Pennsylvania’s Perelman School of Medicine researchers published twice on the technique this month, in Neurology, the American Academy of Neurology’s journal, and Alzheimer’s Disease and Dementia: the Journal of the Alzheimer’s Association.

MRI Not Quite There for Lymph Node Diagnosis in Breast Cancer
Magnetic resonance imaging’s accuracy in detecting cancer in the lymph nodes of newly diagnosed breast cancer patients is nothing to sniff at – 80 percent with diffusion-weighted MRI and 85 percent with axial T1-weighted MRI, Canadian researchers have reported. But it’s not quite high enough to skip a lymph node dissection, according to a study published online Dec. 5 in the journal Radiology.
