MRI pioneer wins national physics prize

...Tesla (T) magnet which was much more powerful than magnets used by others at that time for MR imaging studies...old decision to produce an MRI product using 1.5 T magnets with their very strong magnetic fields. This required the solution of a host of technical problems. ...

Magnetic insoles do not provide pain relief, Mayo Clinic study reports

...ts indicate that patients who strongly believed in magnets had pain relief even if they were given false magnets to wear. "This study provides convincing evidence that use of these static magnets was not effective...

Questions over 'healing effect' of magnets

...ed medicine. More importantly, self treatment with magnets may result in an underlying medical condition being left untreated, they warn. Magnets are touted by successful athletes, allowed to be widely advertised, and sold without restrictions, so it is not surprising that lay people think that claims of the...

Reducing teens' intake of sugary drinks

...ide the home. Monthly phone calls and refrigerator magnets ("Think Before You Drink") provided reminders. The remaining teens, serving as a control group, were asked to continue their usual eating and drinking patterns. At the end of six months, the group receiving beverage deliveries had an 82 percent redu...

Magnetically guided catheter zaps atrial fibrillation

...pped catheter directed by large, computer directed magnets can provide more precise catheter control as compared to manual catheter manipulation. This has the potential, as yet unproven, to shorten the procedure, reduce the length of the learning curve, and perhaps to improve the outcomes of the procedure an...

Heart Rhythm Society to host first ever live remote ablation demonstration

...Clinical research has shown that computer directed magnets can provide more precise catheter control and may carry less risk of complications from surgery. HEART RHYTHM 2006 takes place May 17-20 at the Boston Convention and Exhibition Center in Boston. The meeting is the most comprehensive educational even...

U of MN earns $7.9 million NIH grant to expand neuroscience research

...etic field MR research carried out in CMRR. CMRR's magnets are six times as strong as most MRI machines found in a typical clinical setting. The NIH Blueprint for Neuroscience Research grants were developed as a partnership between 15 NIH institutes and centers to accelerate neuroscience research. As oppose...

Using nanomagnets to enhance medical imaging

Nanoscale magnets in the form of iron-containing molecules might be ... in the literature by showing that iron-containing magnets just two nanometers wide, dissolved in water, do provide reasonable contrast in non-clinical MRI ima...

Physicists set 'speed limit' for future superconducting magnet

Custom-made cancer cell attacks

...m. In the next phase of the project, they will use magnets to separate the specific type of rhenium they need Rhenium 186. Right now, getting Rhenium 186 is a difficult and expensive process, says Ruth. The key is to make this practical for the people who need to use it. In the next few months, we will p...
