CAD, bone suppression find more lung nodules on chest x-ray
By Erik L. Ridley
At the cost of more false positives, the combination of computer-aided detection (CAD) and electronic bone suppression can help radiologists improve detection rates for pulmonary nodules on chest radiographs, according to research published in the May issue of the American Journal of Roentgenology.

AATS: Low-dose CT outruns x-ray for lung cancer surveillance
By Eric Barnes
In a study of more than 300 patients undergoing surveillance after lung cancer surgery, ultralow-dose CT far outperformed chest radiography for detecting cancer recurrence, concluded a study presented this week at the 2013 American Association for Thoracic Surgery (AATS) meeting in Minneapolis.

Cryoablation of lung tumors shows promise as treatment
By Cynthia E. Keen
Cryoablation of metastatic lung tumors up to 3.5 cm in size appears to be an effective treatment, according to early results of a multicenter clinical trial presented at last week's Society of Interventional Radiology annual meeting.

ARRS: Low-dose CT may produce measurement discrepancies
By Wayne Forrest
WASHINGTON, DC - The use of low-dose CT protocols could produce disturbing discrepancies in measurements of lung nodule and lymph node volumes compared with high-dose scans, according to according a study presented Wednesday at the American Roentgen Ray Society (ARRS) meeting.

Bilirubin may be good biomarker for CT lung screening
By AuntMinnie.com staff writers
Male smokers with low levels of serum bilirubin are at much greater risk for lung cancer and could be good targets for low-dose CT screening and other preventative measures, according to research presented at the 2013 American Association of Cancer Research meeting.

3D wide-area CT distinguishes tracheomalacia from stenosis
By Eric Barnes
Dynamic wide-area CT can easily distinguish two different but similar-appearing types of central airway narrowing that are hard to diagnose on conventional MDCT. Even a low-dose protocol captures the information reliably, according to researchers from China.

SPECT V/Q detects early lung problems
By AuntMinnie.com staff writers
In vivo ventilation/perfusion (V/Q) SPECT imaging can detect early changes to lungs caused by cigarette smoke exposure and provides a noninvasive method for studying lung dysfunction in preclinical models, concluded a study published in the April issue of the Journal of Nuclear Medicine.

CT postprocessing can aid evaluation of pediatric airways
By Erik L. Ridley
Because it's noninvasive and doesn't require anesthesia, CT postprocessing offers significant advantages over the gold standard of bronchoscopy for evaluating pediatric airways. Yet there are even more benefits, according to an article published recently in Pediatric Radiology.

CAD scheme automatically characterizes lung nodules
By Eric Barnes
VIENNA - Taking a step beyond lung nodule detection schemes evaluated in previous studies, researchers from the Netherlands have developed an automated method of characterizing nodules as solid, part-solid, or nonsolid, pointing the way to different patient management paths, according to a presentation at ECR 2013.
