Computers beat humans in lung cancer pathology study
By AuntMinnie.com staff writers
A computer machine-learning algorithm handily outperformed pathologists for finding signs of cancer in thousands of slides of lung cancer specimens, concludes a study published online August 16 in Nature Communications.

Advanced visualization tool assesses lung disease
By Eric Barnes
An Australian start-up firm called 4Dx has developed a new technique that combines fluoroscopy and advanced visualization to generate high-resolution images of lung-tissue motion and airflow. The firm hopes the technology will enable researchers to view and measure abnormal function in lung regions at the earliest clinical stages of disease.

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.

Lung abnormalities at CT linked to in-hospital death
By Eric Barnes
In critically ill patients, the presence of interstitial lung abnormalities detected on CT scans increases a patient's risk of dying in the hospital, concludes a recent study. But the modality can help by diagnosing more patients and identifying those at greater risk.

DR tomo beats x-ray, especially for small chest lesions
By Brian Casey
Radiologists who interpreted images acquired with a digital radiography (DR) tomosynthesis system were nearly four times more likely to find chest nodules than those interpreting conventional DR studies -- and tomo's edge grew as the nodules got smaller, according to a new study in Radiology.

COPD severity mirrors lung cancer incidence
By Eric Barnes
A new analysis of patients who participated in the National Lung Screening Trial shows a clear relationship between the severity of chronic obstructive pulmonary disease (COPD) and lung cancer incidence at screening. The findings suggest that COPD patients should be included in CT lung screening programs.

Annual CT follow-up is safe for nonsolid lung nodules
By Kate Madden Yee
It's safe to track patients with nonsolid nodules detected on CT lung cancer screening with annual low-dose CT -- mitigating the need for biopsy or surgery of these lesions, according to a new study published online July 5 in Radiology.

ISCT: Are lung cancer screening programs worth the trouble?
By Eric Barnes
SAN FRANCISCO - Is setting up a lung cancer screening program worth it? The answer depends on many things, including one's tolerance for the hours, costs, and administrative work -- versus the honor of doing some good in the world, concluded a Wednesday talk at the International Society for Computed Tomography (ISCT) 2016 Symposium.

Family doctors unclear on CT lung cancer screening
By Eric Barnes
Most family physicians say they discuss CT lung cancer screening with their patients, but actual screening referrals are rare, even for patients at high risk, according to a study published online June 13 in Cancer.

LDCT could offer a new way to measure breast density
By Kate Madden Yee
Low-dose CT (LDCT) may have another benefit in addition to lung cancer screening: breast density assessment, according to a new study published online in Academic Radiology.
