Rads prefer dual-energy x-ray over standard DR in lung

By Brian Casey

A Canadian study has found that radiologists preferred the image quality of a dual-energy digital radiography (DR) technique over conventional DR in detecting lung lesions. Dual-energy DR produced better soft-tissue delineation thanks to the removal of bony anatomy from images, according to the researchers.

Interobserver variability generally low at lung screening follow-up

By Eric Barnes

Radiologists who perform CT follow-up screening of smokers generally agree on whether a nodule has grown at follow-up and whether the case should be considered positive or negative, according to a study of subjects screened twice in the National Lung Screening Trial. But there was less agreement on what should be done with the results.

Study calculates radiation dose risk for infants in Belgian NICU

By Cynthia E. Keen

A Belgian study has shed additional light on the amount of radiation dose delivered to infants in neonatal intensive care units (NICUs). The research provides reference values for NICU radiation dose, and also offers guidance on collecting dose measurements and converting them into organ-dose values.

Adding CsI-based dual-energy imaging doesn't improve lung nodule detection

By Radiology Review

(Radiology Review) New research suggests that cesium iodide (CsI) detector-based dual-exposure dual-energy imaging, when added to chest radiography, does not significantly improve the detection or classification of pulmonary nodules.

New CT method measures airway calcium to predict lung cancer

By Eric Barnes

In a special "hot topic" presentation at the 2008 RSNA meeting, Ricardo Avila from software developer Kitware said that the presence of calcification at airway bifurcations in CT images can potentially predict lung cancer presence in smokers and former smokers. His company is developing software to exploit the predictive power of such calcifications.
