Germans cast doubt on value of TB screening of refugees
By Frances Rylands-Monk
A new study from Germany involving more than 17,000 refugees has shown mass tuberculosis (TB) screening by chest x-ray is inefficient due to the high number required to detect active pulmonary TB. In a migrant population in which TB prevalence is low, a more targeted approach to screening may be useful.

Vancouver lung cancer predictor works in NLST
By Eric Barnes
A Canadian model for predicting lung cancer risk based on nodule and patient characteristics distinguished benign from malignant lung nodules in patients in the National Lung Screening Trial (NLST), according to a study presented at RSNA 2016. A second study in the same session, however, found that radiologists slightly outperformed the model.

Study: Reduce CT kV levels to lower breast dose in patients
By Rebekah Moan
Despite a short scan length and relatively small dose length product, contrast-monitoring scans can account for 27% of the overall breast dose accrued from a CT pulmonary angiography study, according to Irish researchers. A small tweak to the kilovoltage (kV) can significantly reduce radiation dose to the breast, they noted.

CAD with low-dose CT shows promise in lung
By Frances Rylands-Monk
New Swiss research shows that adding computer-aided detection (CAD) in ultralow-dose CT significantly improves sensitivity for detecting solid pulmonary nodules. This may be a crucial step in the early detection of lung cancer and lead to better patient outcomes.

Texture classification eases lung CT analysis
By Ian Randall
Dutch researchers have developed a semiautomatic method for classifying abnormal lung textures that reduces the time taken to analyze thoracic CT scans. They found the interactive labeling protocol is more efficient to use than a fully automated alternative.

How low can CT radiation dose go for lung screening?
By Eric Barnes
We're making progress in the race to reduce radiation dose for CT lung cancer screening to ever-lower levels. But as dose drops, image noise grows. Fortunately, researchers are refining image processing techniques that can improve image quality while driving CT dose down to the level of a chest x-ray.

Thorax: Lung screening leaves no lasting harm
By Frances Rylands-Monk
Fear can lead to avoidance of lung cancer screening, but a welcome boost has come from a new study analyzing the long-term effects of low-dose CT examinations in the U.K. Lung Cancer Screening trial. It found that patients randomized to the imaging arm did not experience unnecessary long-term anxiety.

Low-dose protocol slashes CT lung screening cancer risk
By Brian Casey
How low can low-dose CT (LDCT) lung cancer screening go? Swiss researchers have tested a new protocol for LDCT screening that reduces radiation dose to nearly the level of a chest x-ray -- a reduction that should lower the risk of a patient developing cancer from the scans in the future.

U.K. team shows survival benefits of CT lung screening
By Eric Barnes
Screening patients at high risk of lung cancer with CT can consistently identify early-stage disease in time for a cure, offering a 73% chance of living five years or more when cancer is detected, concluded an important U.K. pilot study.
