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.

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.

New insight into radiation damage to DNA

A new technique for assessing the damage radiation causes to DNA indicates that the spatial arrangement of damaged sites, or lesions, is more important than the number of lesions in determining the severity of the damage.

Scans spot hidden tumors in Li-Fraumeni syndrome

Researchers at Dana-Farber Cancer Institute report that full-body PET/CT scanning detected unsuspected, treatable tumors in 3 of 15 patients with Li-Fraumeni syndrome (LFS), a rare genetic cancer syndrome for which no screening tests have been recommended.
