Additional CT recommended when FNA is negative
Fine-needle aspiration (FNA) appears to be the best way to diagnose lung cancer when low-dose CT finds suspicious lesions, but it can produce false negatives, according to a new study in the Journal of Thoracic Oncology.

Routine CT lung cancer screening a low-cost lifesaver
Routine CT lung cancer screening of high-risk individuals would save thousands of lives per year for less than a dollar a month per patient if it were implemented throughout the U.S. -- and would be even cheaper than breast screening, concludes a new study in the April issue of Health Affairs.

MESA: Metabolic syndrome, diabetes boost CAC, cardiac events
People with metabolic syndrome and/or diabetes mellitus have greater progression of coronary artery calcium (CAC) than those without the conditions, and the degree of progression in CAC predicts the risk of future cardiac events, according to a study in the Journal of the American College of Cardiology.

'Fatter' phantoms expose radiation's burden on the obese
It is well known that medical radiation dose is greatly affected by patient size, but less well known is the impact of other factors like fat composition. Authors of a new study in Physics in Medicine and Biology got a better handle on dose by creating phantoms that approximate the body habitus of overweight patients.

MDCT generates few new cancers among Medicare patients
Medicare-aged adults get more multidetector-row CT (MDCT) scans than anyone else, but it doesn't seem likely that the scans will kill them, according to a study on the risks of radiation dose in the April issue of the Journal of the American College of Radiology.

Imaging aims to tweak Calif. radiation law before it takes effect
Imaging advocates are beginning their final push for changes in the California radiation protection law -- hoping to have everything settled before the law takes effect in July. The language fixes were amended and passed by the Assembly last week and sent on to the state Senate.
