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.

Esophageal dilatation on CT imaging can indicate scleroderma
By Reuters Health
NEW YORK (Reuters Health), Sep 3 - Esophageal dilatation visible on a high-resolution CT scan of the lungs may be a sign of scleroderma, according to findings published in the September issue of the Annals of the Rheumatic Diseases.

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.

High-intensity ultrasound destroys esophageal tumors
By Reuters Health
NEW YORK (Reuters Health), Jun 20 - Intraluminal high-intensity ultrasound appears to be an effective treatment for esophageal tumors, which are usually not amenable to curative resection, and can even achieve complete tumor necrosis, according to French researchers.

Small lung nodules vex dual-energy DR, study says
By Brian Casey
European researchers found no statistically significant benefit in the use of dual-energy digital radiography (DR) compared with conventional DR for detecting pulmonary nodules. The predominance of small lung nodules in the multicenter study may have exceeded the ability of dual-energy DR to detect them, they wrote.

Ground-glass nodule features on CT reveal malignancy risk
By Eric Barnes
Researchers are peering through a proverbial glass, darkly, to study the features of ground-glass opacities (GGOs). GGOs are being detected with increasing frequency as more thin-section CT lung scans are performed to check for cancer in smokers and former smokers. Distinguishing benign from malignant GGOs is a hit-or-miss task for CT, one that could potentially improve if researchers are able to find reliable signs of malignancy or benignity, thereby reducing the need for invasive biopsy.

Combining chemo and radiation improves NSCLC outcomes for elderly
By Barbara Boughton
SAN DIEGO - French researchers have found that combining chemotherapy with radiation treatment is effective and tolerable for elderly patients with locally advanced non-small cell lung cancer (NSCLC). In a study presented at this week's American Association for Cancer Research (AACR) meeting, the investigators analyzed the efficacy and side effects of chemotherapy and radiation therapy regimens in patients older than age 65.

CAD provides mixed benefits for DR lung exams
By Brian Casey
VIENNA - A pair of presentations on Saturday at the 2008 European Congress of Radiology on computer-aided detection (CAD) for digital radiography (DR) reported mixed benefits for the software in detecting lung nodules in thoracic exams. The presenters discussed their experiences with a commercially available CAD product and its impact on radiologist performance in analyzing DR lung studies.
