Could MRI be used to help detect cracks in teeth?

Magnetic resonance imaging (MRI) technology may be able to help dentists identify those cracks sooner, and intervene before significant damage is done, and/or determine if the tooth is salvable (i.e., not worth crowning), a new study from the University of Minnesota’s School of Dentistry and the Center for Magnetic Resonance Research (CMRR) found.

“Dental MRI,” or imaging of teeth, has never been studied before.

CMRR’s 10.5 Tesla imaging magnet project moves forward

Last December we took you inside the Center for Magnetic Resonance Research’s (CMRR) latest research project – an effort that will utilize the world’s largest imaging magnet to conduct groundbreaking brain research and human body imaging.

In case you missed it, in late 2013 the 110-ton 10.5 Tesla magnet made a spectacular month-long journey by boat across the Atlantic Ocean from England, through the Great Lakes, and finally made its way from Duluth, MN, to the University of Minnesota campus.

Penguin receives MRI at U of M Veterinary Medical Center

Fluffy was having trouble balancing, standing and waddling around when he arrived to the University of Minnesota Veterinary Medical Center in late July.

The male penguin’s radiograph and blood work from his visit to The Raptor Center at the University of Minnesota hadn’t turned up the cause for his illness, so his U of M veterinarian Micky Trent, D.V.M., M.V.S.c., Diplomate A.C.V.S., C.V.S.M.T., was ordering the next step in diagnostic testing:

Fluffy the penguin was about to receive a magnetic resonance imaging scan (MRI).

Expert perspectives: Could new imaging advancements help unlock the mysteries of tau proteins in Alzheimer’s patients?

Last week, researchers from the National Institute of Radiological Sciences in Japan published findings in the journal Neuron signaling that they’d closed in on a diagnostic method to detect tangles of tau proteins previously linked to Alzheimer’s disease.

The work relies on a newly-developed chemical the researchers created that can actually bind to tau proteins in the brain. In turn, positron emission tomography (PET) scanning can then reveal any buildup of these tau proteins in patients suspected of having Alzheimer’s.

So just how big an advancement could this research be?
