Development of Hyper-SAGE was led by one of the world's foremost authorities on MRI technology, Alexander Pines, a chemist who holds joint appointments with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley. The key to this technique is xenon gas that has been zapped with laser light to "hyperpolarize" the spins of its atomic nuclei so that most are pointing in the same direction. http://www.physorg.com/news174319165.html Chemistry Fri, 09 Oct 2009 15:00:36 EST news174319165 Spontaneous brain activity formerly thought to be "white noise" measurably changes after a person learns a new task, researchers at Washington University School of Medicine in St. Louis and the University of Chieti, Italy, have shown. http://www.physorg.com/news174302671.html Medicine & Health Fri, 09 Oct 2009 10:25:17 EST news174302671 University of Utah researchers created new iPhone programs - known as applications or "apps" - to help scientists, students, doctors and patients study the human body, evaluate medical problems and analyze other three-dimensional images. http://www.physorg.com/news174196463.html Technology Thu, 08 Oct 2009 04:55:27 EST news174196463 (PhysOrg.com) -- It is now possible to analyse very small samples using Nuclear Magnetic Resonance.

As a result, previous findings may have overestimated atrophy and underestimated normal size for the older brain. http://www.physorg.com/news171605735.html Medicine & Health Tue, 08 Sep 2009 05:30:01 EST news171605735 A new study has voiced concern about the growing market for brain screening tests, which people can buy as part of a general health MOT. http://www.physorg.com/news171193123.html Medicine & Health Thu, 03 Sep 2009 11:00:01 EST news171193123 New, delicate surgery techniques to hunt for tumours could benefit from a lighter touch - but from a robot, rather than from a human hand. Canadian researchers have created a touchy-feely robot that detects tougher tumour tissue in half the time, and with 40% more accuracy than a human. The technique also minimises tissue damage. http://www.physorg.com/news170067953.html Medicine & Health Fri, 21 Aug 2009 10:06:34 EST news170067953 Breast MRI allows physicians to evaluate suspicious lesions using a variety of variables.

The review, appearing early online in CA: A Cancer Journal for Clinicians, says evidence shows that MRI increases the chances of more extensive surgery over conservative approaches, with no evidence that it improves surgical care or prognosis. http://www.physorg.com/news169373647.html Medicine & Health Thu, 13 Aug 2009 09:15:48 EST news169373647 Noninvasive imaging (MRI) may aid physicians in the early diagnosis, staging and treatment of diabetes, according to a study performed at Massachusetts General Hospital and Harvard Medical School in Boston, MA.
