Cost-effectiveness, implementation still hinder lung cancer screening
By Katrina Megget
The public desire for lung cancer screening and the ability of the medical profession to implement it are currently at odds, despite recent findings that suggest screening via low-dose CT can reduce mortality. The problem is lung cancer screening remains controversial and is not as straightforward as most people think, according to Dr. Stefan Diederich, PhD.

Surgeon input will boost CT lung cancer screening
By Frances Rylands-Monk
CT lung cancer screening is at the fore with 10 new recommendations from the European Society of Thoracic Surgery (ESTS). A recent paper written by an international team outlines the ESTS's plans for improving lung cancer CT screening by involving surgeons at all levels of screening strategy.

CT lung screening cost-effective with stringent criteria
By Eric Barnes
Restricting eligibility for CT lung cancer screening to the heaviest smokers would make the exam more cost-effective on a population basis, according to a study published February 7 in PLOS Medicine.

Ultrasound elevates diagnosis of pulmonary embolism
By Erik L. Ridley
Adding lung and venous ultrasound into the diagnostic process for pulmonary embolism can yield improved sensitivity and specificity, obviating the need for CT pulmonary angiography in many cases, according to research from Italy that will be published in the March issue of Academic Emergency Medicine.

CT lung screening enters pipeline in Middle East
By Inga Stevens
DUBAI - The Abu Dhabi guidelines for CT lung cancer screening were the subject of much debate at the thoracic imaging session during the Total Radiology conference at Arab Health 2017. The guidelines cover an unusual risk factor: 20-year history of water pipe (or shisha) use.

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.
