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.

Lung CT densitometry correlates with lung function, exercise in systemic sclerosis
By Reuters Health
NEW YORK (Reuters Health), Mar 30 - Lung density histogram parameters are more reproducible than visual assessment of lung changes in thin-section CT and are more closely related to lung function, exercise capacity, and quality of life in patients with systemic sclerosis (SSc), results of a recent study indicate.

Dynamic contrast-enhanced MRI shows promise in mesothelioma
By Wayne Forrest
An international group of researchers said they have encouraging preliminary results from the use of dynamic contrast-enhanced MRI (DCE-MRI) to help determine the malignancy of cancer cells in the protective sac -- the mesothelium -- that surrounds most of the body's internal organs.

3D diminution index spots lung nodules attached to blood vessels
By Eric Barnes
BERLIN - A principal limitation of lung cancer imaging is the difficulty of distinguishing lung nodules attached to blood vessels from normal blood vessels, especially in CT data. But researchers from Japan have developed a 3D feature called the diminution index, which scans the CT pulmonary blood vessel data for signs of rapidly expanding shapes that can indicate a nodule rather than a blood vessel.
