MRI's Colorful Future

The Article has images
2008-06-20 08:21:58 by Michael in Medgadget
...MRI images, through the use of special micromagnets, that could be designed to be very specific to particular cells, tissues, or metabolic processes. The researchers believe that such "smart tag" technology could one day improve diagnostic sensitivity and specificity of magnetic resonance imaging From a statement by NIST: Unlike the chemical...

FDA OK's Draeger Fabius MRI Anesthesia Machine

The Article has images
2008-08-19 18:03:26 by Michael in Medgadget
...MRI-compatible Fabius anesthesia machine has received FDA clearance. From now on sedating and anesthetizing all those wiggly toddlers and demented Gomers, who only move at the wrong time, will be easier and safer: no flying oxygen tanks, no five meter ventilating circuits The Fabius MRI is designed for use with 1.5T and 3.0T MRI systems. An...

New MRI Approach for Lung Imaging

The Article has images
2008-04-17 08:09:02 by Michael in Medgadget
...MRI systems used in hospitals are tuned to the resonant frequency of water, and so are designed to visualize "wet" organs. The cost comes when MRI is used in imaging the lungs which are full of air, leading to low quality images. To address this, Massachusetts researchers from the Harvard-Smithsonian Center for Astrophysics and the Martinos...

UC Davis Develops First Combined PET/MRI Tomograph

The Article has images
2008-03-26 17:23:54 by Michael in Medgadget
...MRI scanner. The two imaging modalities are naturally complementary, as MRI provides information about tissue structure while PET is a functional modality that informs about biological processes. Combining the two types of scan in a single machine is difficult because the two systems interfere with each other. MRI scanners rely on very...

Novel Photodetectors Lead to Combination PET/MRI Machines

The Article has images
2008-08-11 18:17:00 by Michael in Medgadget
...MRI machines. Zecotek is leading a collaborative research program with the University of Washington to develop a proprietary PET-MRI detector as the core technology of a new generation of medical imaging systems. The major barrier to a combined PET and MRI scanning device is the strong magnetic fields of MRI which destroy the photodetection...

Cheap, Homemade MRI Does a Better Job Imaging Lungs Than the Real Thing [Medicine]

The Article has images
2008-04-10 11:43:13 by Adam Frucci in Gizmodo
...MRIs. But hey, don't worry. If you need an MRI, you can always just use this makeshift MRI that was built using a cardboard tube, coils of wire, and other items that you can pick up at your local hardware store. The thing is, it really works Built by a couple of researchers at Harvard, the makeshift MRI was cost less than $100,000 to make,...

MRI Used to Watch Brain Repair

The Article has images
2008-03-31 22:48:08 by Michael in Medgadget
...MRI and some nifty eye drops. In this report, Harvard researchers describe how they link a relatively common MRI probe (superparamagnetic iron oxide nanoparticles) to a short DNA sequence that binds to proteins in cells responsible for brain tissue repair (glia and astrocytes). Then, researchers used the eye drops on mice with conditions that...

HYDROCHALARONE MRI Contrast Agent Does Well in Early Study

The Article has images
2008-05-07 18:06:51 by Michael in Medgadget
...MRI image enhancer in the mouse model. HYDROCHALARONE is based on the company's proprietary TRIMETASPHERE molecular cage construct (second picture below), a molecule formed by up to 80 carbon atoms, that is capable of encapsulating a variety of metals (Scandium, Lutetium, Holmium, Gadolinium) inside its cage From the press statement by Luna...

Brain surgery robot uses an MRI to know where to tinker

The Article has images
2008-02-27 13:00:30 by HASH0x8b3b6c4 in DVICE
...MRI tube. It's designed to withstand the powerful magnets of the MRI, using the brain imaging to do very precise surgery without the clumsy fingers of hung over doctors. Hell, if I ever need my brain tinkered with I think I'd trust a robot over a human, especially one this meticulously engineered University of Calgary , via io9
