Decade of lung CAD brings insight, but little daily use
By Eric Barnes
Computer-aided detection (CAD) is known to boost radiologist performance in the detection of lung nodules, and radiologists certainly need the help. But despite a decade of fine-tuning and some powerful new capabilities, CAD systems haven't found a place in daily practice at most imaging facilities

By Eric Barnes
Combined CT scans of the thorax -- which Medicare has been keeping an eye on -- aren't being overused after all. In fact, use of the combined scans is low and falling over time, according to a new study in the Journal of the American College of Radiology.

Automated CT tool reveals pulmonary hypertension
By Eric Barnes
In a new study that used computer-aided analysis, the presence of low normal lung tissue volume correlated with pulmonary arterial hypertension at 3D CT. The technique could offer a more accessible and less invasive diagnostic test than right heart catheterization, according to researchers from Japan.

CT lung screening participants not bothered by false positives
By Eric Barnes
Participants in the massive National Lung Screening Trial weren't troubled by false-positive initial results suggesting they might have cancer -- possibly because they had been well-prepared in advance for such alarms, according to a report published on Friday in Cancer.

AAPM: Radiomics helps fine-tune radiation therapy dose
By Wayne Forrest
By extracting statistical information and other measurements from PET images using a data analysis technique called radiomics, researchers have developed a way to determine radiation therapy dose more accurately, according to a study presented this week at the American Association of Physicists in Medicine (AAPM) meeting.

Nodule size matters in Italian CT lung cancer screening study
By Eric Barnes
Italian researchers believe they have struck a good balance in CT lung cancer screening by following up suspicious nodules at a slightly larger size threshold than that used in previous studies. By only following up nodules 5 mm and larger rather than 4 mm, they achieved good sensitivity with fewer false positives, according to a new study in the Journal of Thoracic Oncology.

Lung cancer screening of seniors: Should CMS regulate?
By Eric Barnes
A just-published proposal in the Annals of Internal Medicine seeks to balance the benefits and harms of CT lung cancer screening by limiting the screening of Medicare beneficiaries to lung cancer screening centers that would be accredited based on still-evolving society-based guidelines.

Consumer-grade displays can tackle image viewing
By Erik L. Ridley
Even without DICOM calibration, consumer-grade color displays can perform comparably to medical-grade grayscale LCDs for reading chest radiographs, Colombian researchers reported in the June issue of the American Journal of Roentgenology.
