Radiosurgery advised for postpneumonectomy recurrent lung cancer
By Cynthia E. Keen
A large study of patients who developed contralateral lung cancer after having a pneumonectomy suggests that stereotactic radiation therapy is a curative option with minimal toxicity, even for high-risk patients with chronic obstructive pulmonary disease.

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.

MIP boosts detection of small pulmonary nodules
By Erik L. Ridley
CHICAGO - Performing maximum intensity projection (MIP) reformatting of MDCT studies adds significant utility for finding pulmonary nodules less than 10 mm in size, according to research from the University Medical Center Hamburg-Eppendorf in Hamburg, Germany.

Lung CAD holds up well in low-dose MDCT studies
By Erik L. Ridley
Computer-aided detection (CAD) technology offers comparable performance in low-dose and standard-dose MDCT chest studies, according to research published in the British Journal of Radiology. The research team from Germany retrospectively evaluated chest CT examinations of 77 patients for pulmonary nodules.

Nodule measurement streamlined with space-scale analysis
By Eric Barnes
Researchers from Florence, Italy, have developed a robust and accurate method of measuring most lung nodules, improving the odds that growing lesions can be detected at CT with greater accuracy and reproducibility compared to current methods that rely on prior segmentation of the CT data.

MRI used to diagnose complex lung infections in children
By Cynthia E. Keen
CT is the gold standard for lung imaging, particularly when a chest x-ray lacks the detail needed to make a diagnosis. But CT's far higher radiation dose -- equivalent to 200 chest radiographs -- has some pediatric radiologists looking for an alternative modality, especially for children with chronic lung conditions who may require many CT scans.

PACS data-mining tool analyzes CR retake rates
By Brian Casey
Researchers from Spain have developed software that analyzes PACS data to automatically perform quality control analysis of retake rates of computed radiography studies. They believe their QC tool could make it easier for imaging facilities to reduce retakes and improve the overall quality of service.
