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.

Novel angled gantry approach reduces breast radiation exposure

A novel angled gantry approach to coronary CT angiography reduced radiation exposure to the breast by more than 50%, according to Thomas Jefferson University researchers.

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.

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.

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).

No such thing as a 'safe' suntan

Three review papers from leading researchers in the fields of cell biology, dermatology and epidemiology have looked closely at the effects on skin of UV radiation, including that from indoor tanning beds.

Atomic bomb's effect results in adult-onset thyroid cancer

Radiation from the atomic bomb blasts in Hiroshima and Nagasaki, Japan, in 1945, likely rearranged chromosomes in some survivors who later developed papillary thyroid cancer as adults, according to Japanese researchers.

Robotic navigation systems in electrophysiology

Catheter ablation is still associated with a substantial amount of complications, and more failure then sometimes reported. Perforation with catheters is especially important in atrial fibrillation. Robotic navigation could reduce these complications.

New imaging technology lights up lungs to diagnose disease

Researchers at the University of Sheffield have developed innovative technology which illuminates a person's lungs and helps clinicians identify if they are functioning correctly. The new technology could result in earlier diagnosis of emphysema and smoking related damage, as well as other lung conditions and diseases.
