Lung cancer risk model optimizes follow-up CT screening
By Abraham Kim
How might a lung cancer risk-prediction model improve follow-up CT screening? A model that incorporates patient characteristics and CT data could allow many individuals to skip the first annual follow-up screening exam -- reducing costs and radiation exposure, according to research published online recently in Thorax.

CADx volumetry predicts lung cancer recurrence on CT
By Abraham Kim
Measurements of lung nodule volume on CT scans made with computer-aided diagnosis (CADx) software were more accurate than conventional measurements of nodule diameter in predicting the recurrence of subsolid lung cancer in patients who underwent surgery, according to a recent study published in Radiology.

Does organ-specific CT dose reduction really reduce dose?
By Abraham Kim
Researchers from Belgium are questioning whether organ-based tube-current modulation in CT chest studies of women really reduces radiation dose. They found that while radiation dose to the breast fell, it increased in other areas, according to a study published on March 27 in Radiology.

Ky. takes black lung x-ray reads away from radiologists
By Brian Casey
Radiologists in Kentucky are no longer allowed to read x-rays of miners who claim to have black lung disease under legislation signed into law last week. Instead, the law gives pulmonologists the exclusive right to interpret such studies, according to a March 31 report by NPR.

Google AI algorithm shows promise for chest x-rays
By Erik L. Ridley
How many radiologist-annotated images are needed to train a deep-learning algorithm for radiology applications? Perhaps not as many as you might think. Using both annotated and unannotated images, researchers from Google have developed an algorithm that can simultaneously identify and localize disease found on chest x-rays.
