Wearable scanner maps rat brains 2011-03-14T11:56:34Z Compared with conventional X-rays, the CT, or computed tomography, scans create a detailed three-dimensional image of the lungs. Well: The Downside of a Cancer Study Extolling CT Scans 2010-11-16T15:20:00Z They said the rate of growth is untenable, and needs to be tempered by the extra costs and risks associated with the use of computed tomography or CT scans, which expose patients to radiation. Advanced imaging use in emergency rooms triples 2010-10-05T20:37:00Z Many brain imaging studies, using positron emission tomography, show that cues like viewing drug paraphernalia are enough by themselves to activate memory circuits and unleash drug craving. Mind: Lasting Pleasures, Robbed by Drug Abuse 2010-08-30T20:16:00Z The scanner made by Philips, using a method called multicolor computed tomography, or CT, showed the gold particles heading to the dangerous artery-clogging plaque, the team reported in the September issue of the journal Radiology. Gold in scan finds dangerous artery clogs: U.S. study 2010-08-16T22:39:00Z The team tested 238 young rhesus monkeys using a high-resolution type of positron emission tomography or PET scan. Nervous monkeys lend clues to childhood anxiety 2010-08-11T22:36:00Z Called optical tomography, the test combines ultrasound with two frequencies of infrared light to survey a suspicious area and determine the presence of high oxygen consumption, indicating the presence of cancer. Beyond Flip-Of-A-Coin Breast Cancer Diagnosis 2010-07-27T15:00:00Z The investigations found that the center — regarded by experts as the nation’s leader in the use of positron emission tomography, or PET, for psychiatric research — repeatedly violated regulations over a four-year period. Brain Center at Columbia Gave Patients Impure Drugs 2010-07-17T03:40:00Z All three of the imaging tests are designed to cause beta amyloid clumps to light up when patients' brains are scanned using PET, or positron emission tomography. Study finds brain dye can detect Alzheimer's 2010-07-13T00:07:00Z Magnetic resonance imaging or MRI detected strokes 83 percent of the time, compared to just 26 percent for computed tomography or CT scans, the group advised. New guideline says MRI best for diagnosing stroke 2010-07-12T20:22:00Z And they did an imaging test called positron emission tomography or PET to test for brain function by looking to see how well the brain uses glucose or sugar. Study identifies best tests to predict Alzheimer's 2010-06-30T22:52:00Z In a recently completed trial involving 178 women, when optical tomography suggested an area wasn't cancer, 97% of the time it was also confirmed by the biopsy. Beyond Flip-Of-A-Coin Breast Cancer Diagnosis 2010-07-27T15:00:00Z An atomic force microscope, similar to one used on NASA's Phoenix Mars Lander, and micro-computed tomography, used to measure bone density, helped reveal how ingredients interact with different hair types. Procter & Gamble's Root-to-End Pantene Makeover 2010-05-20T21:00:00Z The researchers used an imaging technology called X-ray computerised tomography to scan a live beehive. 3D images of live honeybee colony 2010-05-17T03:36:00Z Imaging tools commonly used to detect breast cancer include PET/CT, a combination of positron emission tomography and a CT scan, chest X-rays, bone scans, and ultrasound of the abdomen and pelvis. MRI scans accurately spot spread of cancer: study 2010-05-06T22:07:00Z They said the use of positron emission tomography or PET scans, which show both anatomy and organ function, grew the fastest. Cost of imaging cancer patients rising sharply 2010-04-27T20:26:00Z The downside is that, like mammograms, ultrasound requires a mass of millions of cells or more in order for effective detection and the optical tomography is affected by irregularities in breast tissue. Beyond Flip-Of-A-Coin Breast Cancer Diagnosis 2010-07-27T15:00:00Z He called the technique computed tomography, or CT. From success of the Fab Four, a key driver of health-care costs arose 2010-02-21T05:00:00Z Computed tomography, for instance, visualized the internal structure of Egyptian mummies. The Civilization of Illiteracy PET scans cost six times more than an advanced type of X-ray called a computed tomography or CT scan. Cost of imaging cancer patients rising sharply 2010-04-27T20:26:00Z |
