Radiology is the medical specialty directing medical imaging technologies to diagnose and sometimes treat diseases. Originally it was the aspect of medical science dealing with the medical use of electromagnetic energy emitted by X-ray machines or other such radiation devices for the purpose of obtaining visual information as part of medical imaging.

CT colonography not presently a viable option for colorectal cancer screening

Findings of a new multicenter study by Cotton et al. published today in the Journal of the American Medical Association comparing standard colonoscopy with CT colonography for the detection of colorectal cancer reveal that this technology, in the form used most often in the United States, while of significant interest, is not presently a viable option for routine colorectal cancer screening.

Differing views on virtual colonoscopy accuracy

Demonstrating clearly that not all virtual colonoscopies are equal, the study, published in the December 2003 issue of The New England Journal of Medicine and the American Journal of Roentgenology, found the results found using the Viatronix V3D-Colon system for primary 3D reading to be equal to or better than optical colonoscopy results.

Lung tumor therapies improved by combining scanning technologies

Physicians targeting lung tumors for radiation therapy can substantially improve their aim by combining data from two scanning techniques, according to Washington University researchers at Siteman Cancer Center and Barnes-Jewish Hospital in St. Louis.

Researchers examine community-based drinkers rather than abstinent alcoholics

Almost all knowledge about brain damage due to chronic alcohol consumption has been gathered from alcoholics, who have generally been studied toward the end of their institutionalized treatment program (several weeks after their last drink) or many months into abstinence.

Women treated with radiation therapy to cure Wilms tumor can have healthy babies if entire pelvis was not irradiated

Women who were treated with radiation therapy to cure Wilms tumor as a child can go on to have healthy babies so long as their entire pelvis was not irradiated, according to a new study in the April 2004 issue of the International Journal of Radiation Oncology-Biology-Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology.

Research shows giving Tourette Syndrome patients the drug levodopa normalizes brain activity

Scientists have known for years that abnormal activity involving a brain chemical called dopamine is somehow connected to the movements and vocalizations, or tics, associated with Tourette syndrome. Now neuroscience researchers at Washington University School of Medicine in St. Louis have found brain activity in these patients is abnormal during memory tasks, as well.

Michigan opens new center to treat exposure to Vermiculite, Taconite, Asbestos

In response to the United States Environmental Protection Agency's (EPA) identification of major sources of public asbestos exposure in Michigan, the Barbara Ann Karmanos Cancer Institute and the Center for Occupational and Environmental Medicine (COEM) affiliated with Wayne State University (WSU) have joined forces to establish The National Center for Vermiculite and Asbestos-Related Cancers.

Removal of thyroid glands may be unnecessary for most patients

An unpleasant postoperative procedure for thyroid cancer patients who have had their thyroid glands surgically removed may be unnecessary for most patients, according to Washington University researchers at Siteman Cancer Center and Barnes-Jewish Hospital in St. Louis.

Stenting for Stroke Prevention is More Effective Than Surgery in Keeping Blood Vessels Open

Research presented in a six-hour symposium on carotid artery disease at the 29th Annual Scientific Meeting of the Society of Interventional Radiology showed carotid artery stenting to be safe and effective for highrisk patients. Currently, the standard of care for stroke prevention in patients with moderate to severely blocked carotid arteries is carotid endarterectomy surgery. The ARCHeR trials treated patients who were high-risk surgical candidates with carotid artery stenting with and without embolic protection, a device to capture debris that may break off during the procedure.

Study suggests cigarette smoking increases likelihood of death by prostate cancer

Although cure rates for prostate cancer patients who smoke cigarettes are about the same as patients who do not smoke, researchers have found that smokers were more likely to die of other causes than non-smokers, according to a new study in the March 15, 2004, issue of the International Journal of Radiation Oncology•Biology•Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology.

Side Effects of Diabetes Drugs Involve Unsuspected Brain Region

A brain region involved in emotional and intellectual processes appears to also play an unsuspected role in the body’s visceral response to dangerously low blood sugar levels, according to research at Washington University School of Medicine in St Louis. Low blood sugar, called hypoglycemia, is a common and dangerous side effect of drugs that control insulin levels in people with diabetes.

New treatment for heart attacks

A team led by scientists at The Scripps Research Institute has developed a potential new treatment for heart attacks. The therapy inhibits fluid leakage from cardiac blood vessels following a heart attack and thereby significantly prevents long-term heart damage and improves survival.
