Study explains why up to eight percent of cancers go undetected
A few years ago, Medhat Osman, M.D., Ph.D., had a patient who was scanned due to a suspicion of lung cancer using positron emission tomography (PET) and computer tomography (CT) technology. The scan came back negative, but the patient then complained of a problem with his leg. view more (2005-06-15)
New imaging technique could promote early detection of multiple sclerosis
Researchers from Purdue University have studied and recorded how myelin degrades real-time in live mice using a new imaging technique. Myelin is the fatty sheath coating the axons, or nerve cells, that insulate and aid in efficient nerve fiber conduction. In diseases such as multiple sclerosis, the myelin sheath has been found to degrade. view more (2007-06-28)
MRI can track survival of pancreatic islets after transplantation
Magnetic resonance imaging (MRI) with an approved contrast agent may provide a practical way of monitoring the survival of transplanted pancreatic islets. view more (2006-09-13)
NASA's Cassini Reveals Lake-Like Feature on Titan
Scientists are fascinated by a dark, lake-like feature recently observed on Saturn's moon Titan. NASA's Cassini spacecraft captured a series of images showing a marking, darker than anything else around it. It is remarkably lake-like, with smooth, shore-like boundaries unlike any seen previously on Titan. view more (2005-06-29)
The first 3 Teslas magnetic resonance imager for research
The University Hospital at the University of Navarra and the Applied Medicine Research Centre (CIMA) of the University has recently acquired a 3 Teslas magnetic resonance imager for joint use, the first for research applications in Spain. view more (2006-10-27)
Toward world's smallest radio: nano-sized detector turns radio waves into music
Researchers report development of the world's first working radio system that receives radio waves wirelessly and converts them to sound signals through a nano-sized detector made of carbon nanotubes. view more (2007-10-18)
MRI detects early heart damage in patients with sarcoidosis
To detect heart damage early in patients with the immune system disorder sarcoidosis, who are at elevated risk of dieing from heart problems, magnetic resonance imaging is twice as sensitive as conventional methods. view more (2006-11-13)
From Physics to Physicians
The Particle Physics and Astronomy Research Council (PPARC) and the UK Health Departments have signed a concordat to formally recognise and explore the potential for collaboration in technological areas of common interest. The Concordat, signed by Professor Ian Halliday, Chief Executive of PPARC and Professor Sir John Pattison, Director of... view more... (2002-05-22)
MIT device could prevent epileptic seizures
Researchers at MIT are developing a device that could detect and prevent epileptic seizures before they become debilitating. view more (2006-09-13)
Advances in brain imaging for epilepsy
Positron emission tomography (PET) brain scans of a brain chemical messenger system may prove sensitive enough to help plan brain surgery for epilepsy, according to a study presented at the 130th annual meeting of the American Neurological Association in San Diego. view more (2005-09-22)
With double frequency to deeper blue
Light transports data at high speed over fibre-optic networks. Light measures and creates images of large and small objects in scanners and microscopes. Light writes information onto all sorts of recording media and surfaces. The best-quality light is produced by lasers, which have meanwhile become an indispensable tool - not only in medicine and... view more... (2003-07-01)
Where has all the antimatter gone?
Scientists from the Universities of Liverpool and Glasgow have completed work on the inner heart of an experiment which seeks to find out what has happened to all the antimatter created at the start of the Universe. view more (2007-04-12)
New Non-Invasive Method In Lung Diagnostics
Magnetic resonance imaging (MRI) as a non-invasive diagnostic method has been evolving into an attractive alternative to methods which are associated with radiation exposure. This development now also starts to manifest itself in lung perfusion imaging. This was reported by Dr. Christian Fink and colleagues of the Radiology Division of the... view more... (2004-06-24)
Lombardi Expert Helps Set New Guidelines for Assessing Lymphoma Treatment
An international team of cancer specialists and imaging experts, including Bruce Cheson, professor of medicine, head of hematology, and director of hematology research at Georgetown's Lombardi Comprehensive Cancer Center, has developed standardized guidelines for assessing how lymphomas respond to treatment. view more (2007-02-07)
New coil to make magnetic resonance (MR) imaging easier
Oxford University researchers have devised a novel coil design for magnetic resonance (MR) application, devised specifically for deep organ MR where sensitive imaging and spectroscopy have been previously difficult. Deep organ magnetic resonance requires maximised sensitivity and magnetic field homogeneity over a relatively large field of view... view more... (2003-01-24)
PET imaging identifies aggressive kidney cancers that require surgery
The ability to identify an individual's specific tumor type prior to surgery could have important implications for the management of patients diagnosed with kidney cancer. view more (2007-03-07)
A Single-Photon Server with Just One Atom
Every time you switch on a light bulb, 10 to the power of 15 (a million times a billion) visible photons, the elementary particles of light, are illuminating the room in every second. If that is too many for you, light a candle. view more (2007-03-13)
Rice's single-pixel camera takes high-res images
For all their ease and convenience, there are few things more wasteful than digital cameras. They're loaded with pricy microprocessors that chew through batteries at a breakneck pace, crunching millions of numbers per second in order to throw out up to 99 percent of the information flowing through the lens. view more (2006-10-03)
GAMMA RAYS AND DARK MATTER
For a long time it has been known that the Milky Way is surrounded by a (nearly spherical) halo of invisible matter, which contributes at least 90% of the whole galactic mass. Yet, almost nothing is known about the nature of such a dark halo. view more (1999-02-26)
Liver diagnosis breakthrough with Mayo Clinic MRI development
Mayo Clinic researchers have developed a new technique for using magnetic resonance imaging (MRI) to accurately measure the hardness or elasticity of the liver. First tests show this technology - called MR Elastography (MRE) - holds great promise for detecting liver fibrosis, a common condition that can lead to incurable cirrhosis if not treated... view more...
