RoeKo: Phase-contrast imaging looks set for clinical use
After years in development, phase-contrast imaging is ready for clinical use, and one of its first functions could be to view the lungs of patients with a variety of pulmonary diseases, according to an expert from the German Radiology Congress (Deutscher Röntgenkongress, RöKo 2017).

Ditch x-ray to diagnose COPD, study finds
By Rebekah Moan
In the quest to diagnose mild-stage chronic obstructive pulmonary disease (COPD), radiologists often use chest radiographs, but Dutch researchers of a new study advise that they shouldn't do so because it results in substantial overdiagnosis.

PACS alerts can boost communication with referrers
By Philip Ward
A fatal accident due to an oversight by a referring physician has prompted staff at a radiology department to implement a PACS alert system, and it's already helping to improve communication and collaboration between radiologists and referring physicians.

Women may need less frequent CT lung cancer screening
By Eric Barnes
Women may need less frequent CT lung cancer screening than men, according to a study to be presented on 6 May at the European Lung Cancer Conference in Geneva. The finding could enable physicians to reduce CT screening frequency (and thus exposure to radiation) in women.

Lung-RADS category 4X helps diagnose lung cancer
By Eric Barnes
The addition of category 4X lesions in the Lung CT Screening Reporting and Data System (Lung-RADS) imaging scheme adds value and increases malignancy yields among experienced radiologists, according to a Dutch study in Radiology. The 4X nodules turn out to be malignant in half of cases.

Italian CT trial boosts lung cancer screening
By Rebekah Moan
An Italian CT lung cancer screening trial has found low-dose CT screening could reduce lung cancer and overall mortality, and it is the first European study to show results clearly in the same direction of other major lung cancer screening trials.

Ultralow-dose CT works for emphysema quantification
By Frances Rylands-Monk
A Swiss study has shown that a CT protocol using tin filtration and iterative reconstruction reduces radiation dose levels to the equivalent of a chest x-ray for lung volumetry and also the detection and quantification of emphysema. The results nudge ultralow-dose CT ever closer to routine workup of chest pathologies.

IR with CAD permits ultralow lung CT dose
By Eric Barnes
Iterative reconstruction (IR) can improve lung nodule detection with 3D computer-aided detection (CAD) to the point where nodule detection using ultralow-dose CT is comparable with standard and low-dose exposures, according to researchers from Japan presenting at ECR 2017 in Vienna.

Chest CT with iterative recon achieves x-ray doses
By Eric Barnes
VIENNA - Chest CT scans acquired at radiation doses as low as an x-ray showed lesions of all kinds conspicuously, using the latest dual-source CT scanner and iterative reconstruction. Individualized approaches tailored to specific lesion types cut the dose even further, researchers said on Friday at ECR 2017.

Video from ECR 2017: Dr. Martine Rémy-Jardin on pulmonary embolism
VIENNA - When you mention pulmonary embolism (PE), the chances are you will think of Dr. Martine Rémy-Jardin, PhD, head of the cardiothoracic imaging department at the University Centre of Lille in France. In this video interview, she speaks about persistent controversies in PE and how to optimize patient management.

CAD beats readers for subsolid lung nodules
By Eric Barnes
VIENNA - A computer-aided detection (CAD) scheme outperformed experienced human readers in detecting subsolid nodules as well as cancers in data from more than 2,000 lung cancer screening subjects, researchers reported on Thursday at ECR 2017.

Software quantifies emphysema on MDCT images
By Erik L. Ridley
VIENNA - An automated software algorithm can be used to quantify emphysema on MDCT studies, offering radiologists a useful tool for diagnosis and follow-up of chronic obstructive pulmonary disease, according to research presented on Thursday at ECR 2017.
