Researchers cut false positives in lung CAD
By Eric Barnes
One of the thorniest challenges in computer-aided detection (CAD) is the high rate of false-positive detections, a number that generally rises in tandem with the sensitivity of the CAD algorithm. University of Tokyo researchers recently set out to develop a new false-positive reduction method based on dual classifiers for juxtapleural and nonpleural nodules.

Digital chest tomo beats standard DR for pulmonary nodules
By Brian Casey
A new study published this month in Radiology by Swedish researchers scores another point for tomosynthesis-based digital radiography (DR) over conventional DR. The study found that tomosynthesis showed better sensitivity in detecting pulmonary nodules, particularly those smaller than 9 mm.

MRI used to diagnose complex lung infections in children
By Cynthia E. Keen
CT is the gold standard for lung imaging, particularly when a chest x-ray lacks the detail needed to make a diagnosis. But CT's far higher radiation dose -- equivalent to 200 chest radiographs -- has some pediatric radiologists looking for an alternative modality, especially for children with chronic lung conditions who may require many CT scans.

Dual-energy CT helps distinguish malignant lung nodules
By Eric Barnes
Researchers in South Korea used a dual-energy CT (DECT) scan to perform a lung imaging task that previously required two scans, reducing the radiation dose needed for the workup. The group found that DECT enabled the detection of both contrast enhancement and lung nodule calcifications in a single scan.

CAD detects more lung nodules but not necessarily more cancer
By Erik L. Ridley
Computer-aided detection (CAD) technology can significantly improve the overall performance of radiologists in detecting lung nodules, but it may not provide a statistically significant difference for detecting more lung cancer, according to research published in the Journal of Computer Assisted Tomography.
