UC Davis team refines cancer treatments to reduce potential nerve damage

While radiation treatments deliver precise doses of high-energy X-rays to stop cancer cells from spreading or to shrink tumors, oncologists have become increasingly concerned about inadvertent exposures during head and neck cancer treatments to nerves responsible for upper body mobility.

High phosphorus levels in blood linked to coronary calcification in chronic kidney disease

For patients with moderate chronic kidney disease (CKD), higher levels of phosphorus in the blood are associated with increased calcification of the major arteries and heart valves - which may contribute to the increased risk of cardiovascular disease in patients with CKD, reports a study in the Journal of the American Society of Nephrology (JASN).

Cancer risk from cardiac computed tomography overstated

Radiology and cardiovascular researchers from the Medical University of South Carolina in Charleston, S.C., today present 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.

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).

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.

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).

Symptoms of fibromyalgia related to dysfunction in parts of brain where pain is processed

Using single photon emission computed tomography (SPECT), researchers in France were able to detect functional abnormalities in certain regions in the brains of patients diagnosed with fibromyalgia, reinforcing the idea that symptoms of the disorder are related to a dysfunction in those parts of the brain where pain is processed.
