Portable eight-slice CT in ER increases chance of stroke survival and recovery

New research has found that the availability of a portable eight-slice computed tomography (CT) scanner in an emergency room can significantly increase the number of stroke victims who receive a potentially life-saving treatment.

Patient photos help counteract anonymity common in radiologic exams

Including a patient's photo with imaging exam results may enable a more meticulous reading from the radiologist interpreting the images, as well as a more personal and empathetic approach, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA).

Positron emission mammography effective in detecting breast cancer

A study has found that positron emission mammography (PEM), a new technique for imaging the breast, is not affected by either breast density or a woman's hormonal status, two factors that limit the effectiveness of standard mammography and MRI at detecting cancer.

Virtual colonoscopy has potential to screen for colorectal cancer and osteoporosis at same time

New research reveals that computed tomography (CT) colonography, also known as virtual colonoscopy, has the potential to screen for two diseases at once-colorectal cancer and osteoporosis, both of which commonly affect adults over age 50.

Advanced CT scans 100 percent accurate in checking for clogged arteries

In a development that researchers say is likely to quell concerns about the value of costly computed tomography (CT) scans to diagnose coronary artery blockages, an international team led by researchers at Johns Hopkins reports solid evidence that the newer, more powerful 64-CT scans can easily and correctly identify people with major blood vessel disease and is nearly as accurate as invasive coronary angiography.

Mechanisms of cardiovascular disease and cancer give clues to new therapies

Cardiovascular conditions leading to heart attacks and strokes are treated quite separately from common cancers of the prostate, breast or lung, but now turn out to involve some of the same critical mechanisms at the molecular level.

Computed tomography technology shows anorexia impairs adolescent bone development

Children and teenagers with even mild cases of anorexia exhibit abnormal bone structure, according to a new study appearing in the December issue of Radiology and presented at the annual meeting of the Radiological Society of North America (RSNA).

Optical frequency-domain imaging provides 3-D view of human coronary arteries

For the first time researchers are getting a detailed look at the interior of human coronary arteries, using an optical imaging technique developed at the Wellman Center for Photomedicine at Massachusetts General Hospital (MGH).

Higher levels of blood phosphate may be a previously unidentified and modifiable cardiovascular risk factor

Healthy adults with higher levels of phosphate in the blood are more likely to have increased levels of calcium in the coronary arteries-a key indicator of atherosclerosis and future cardiovascular disease risk, reports a study in the February 2009 issue of the Journal of the American Society of Nephrology (JASN).

Study finds rise in rate of diagnostic imaging in managed care

Use of radiology imaging tests has soared in the past decade with a significant increase in newer technologies, according to a new study that is the first to track imaging patterns in a managed care setting over a substantial time period.

Cancer risk from cardiac CT overstated

Radiology and cardiovascular researchers from the Medical University of South Carolina in Charleston, S.C., today presented new data that shows the risk of cancer from exposure to radiation during computed tomography for cardiovascular disease has been overstated and that new estimates are several times lower than previously published conclusions.

Education delays onset of the dementia

A test that reveals brain changes believed to be at the heart of Alzheimer's disease has bolstered the theory that education can delay the onset of the dementia and cognitive decline that are characteristic of the disorder.

Greater thinking, learning and memory abilities delay symptoms of Alzheimer's disease

Individuals with higher education levels appear to score higher on cognitive tests despite having evidence of brain plaques associated with Alzheimer's disease, according to a report in the November issue of Archives of Neurology , one of the JAMA/Archives journals.

Education lessens the effects of Alzheimer's

The scientists from the Washington University School of Medicine, St. Louis, say their research supports the 'cognitive reserve' hypothesis and individuals with levels of higher education levels score higher on cognitive tests despite having Alzheimer's disease.
