Helium diffusion MRI shows early view of secondhand smoke lung damage
By Edward Susman
CHICAGO - The use of hyperpolarized helium diffusion MRI allows clinicians to assess early changes in the lungs of individuals exposed to secondhand smoke, researchers reported in a presentation on Monday at the RSNA 2007 meeting.

Ungated calcium CT scans could permit dual-purpose screening
By Eric Barnes
CHICAGO - Could a one-scan CT lung screening and cardiac risk assessment be feasible? Perhaps, say researchers from South Korea who performed low-dose thoracic multidetector-row CT (MDCT) in a group of smokers and ran calcium tests on the data. They shared their results in a presentation Sunday at the RSNA 2007 meeting.

Computer-aided program can help match metastatic lung nodules
By Erik L. Ridley
A computer-aided matching program can yield a high rate for matching metastatic pulmonary nodules on clinical series CT scans, provided that lung findings and lung expansion between the serial scans are relatively unchanged, according to a team from the Mallinckrodt Institute of Radiology in St. Louis.

Low-dose CT again finds early, curable lung cancers
By Eric Barnes
A Canadian lung cancer screening study has found, once again, that thin-section CT screening identifies small resectable lung cancers in time to potentially cure the disease. Researchers from the University of Toronto in Canada participated as an International Early Lung Cancer Action Program (I-ELCAP) trial center, and used ELCAP criteria to guide follow-up and intervention of their cohort of smokers and former smokers.

Measuring lung nodule growth beyond variability
By Eric Barnes
Two recent studies focused on measuring solitary pulmonary nodule (SPN) growth, with the first assessing the precision of semiautomated volume measurements at low-dose multidetector-row CT. In the second, researchers discuss the evidence-based decision to follow up or resect SPNs based on volume doubling time, and accounting for measurement variability.
