Lower dosage CT-guided lung biopsy protocol maintains quality, minimizes exposure
Date:3/25/2012

New guidelines for CT-guided biopsies of lung nodules significantly reduce radiation exposure allowing individuals the benefit of the procedure, which may cut down on overall lung cancer deaths. This research is being presented at the Society of Interventional Radiology's 37th Annual Scientific Meeting in San Francisco, Calif.

"The published early results of a trial using computed tomography to detect lung nodules demonstrated that screening with low-dose CT reduced mortality from lung cancer by 20 percent compared to screening with chest X-rays alone," said Jeremy Collins, M.D., assistant professor of radiology at Northwestern University in Chicago, Ill. "Statistically, many people who undergo screening will have nodules detected with CT and a biopsy may be recommended. We want to minimize the side effects of the biopsy procedure," he added.

The medical community evaluates the risks of radiation exposure on patients. While there is debate about the actual risk of cumulative exposure from the types of medical imaging that emit radiation, interventional radiologists are trying to curb patient dose. CT has been gaining recognition as the most effective imaging technique for lung nodules since it is more sensitive than chest X-rays and all other imaging tests.

"Lung nodules are clearly imaged using CT because of the high contrast between normal air-containing lung tissue and higher-density lung nodules. CT technologies have come a long way in offering new tools that reduce the per-procedure radiation dose," said Collins.

This research focuses on a new set of CT imaging parameters to further reduce radiation exposure while maintaining image quality. The new protocol downshifts the amount of energy the CT scanner uses to produce images and moderates the current of the X-ray tube to put out a smaller dose during examination.

"All image studies using X-ray technology are going to be associated with a small amount of fi
