Combined PET/CT CAD improves lung nodule detection
By
Eric Barnes
Researchers in Japan have developed computer-aided detection (CAD) software that detects lung nodules in PET/CT images of lung cancer screening patients. Applying a combined CAD system to both modalities instead of CT or PET alone nearly doubled the number of solitary pulmonary nodules detected.

Study finds clinical niche for DR tomo in pulmonary lesions
By
James Brice
Imaging researchers have long known that chest tomosynthesis is more sensitive than conventional x-ray for detecting malignant pulmonary lesions, while producing lower radiation dose than CT. Now, they are zeroing in on a precise role for this unique technology.

By
Reuters Health
NEW YORK (Reuters Health), Jul 14 - More than a quarter of patients with abdominal aortic aneurysms also have thoracic aortic aneurysms, and the proportion is twice as high in women, Swedish researchers report in the

PET/CT beats CT in NSCLC staging, but both have limitations
By
Wayne Forrest
While no imaging or invasive procedure is foolproof for staging non-small cell lung cancer (NSCLC), Danish researchers have found that PET/CT is more accurate than CT alone, though both modalities had a tendency to understage and overstage the cancer.

CT method measures airway calcium to diagnose lung cancer
By
Eric Barnes
A classic duo, CT plus pulmonary function testing using spirometry, may emerge once again as a potentially effective way to diagnose lung cancer, according to an article in the July issue of

Lung CAD performs best as second reader
By
Erik L. Ridley
Computer-aided detection (CAD) software yields a higher level of sensitivity for identifying lung nodules as a second reader than when used concurrently during image interpretation, according to research from the University of Verona in Italy.

Accelerated RT improves lung cancer survival
By
AuntMinnieEurope.com staff writers
Patients diagnosed with non-small cell or small cell lung cancer that has not metastasized have better overall survival outcomes when treated with hyperfractionated or accelerated radiation therapy (RT), according to a new meta-analysis.

CAD, PACS pairing boosts lung nodule detection, saves time
By
Erik L. Ridley
The use of computer-aided detection (CAD) technology as a concurrent reader on PACS workstations can improve the performance of inexperienced readers in detecting lung nodules, according to a study from Catholic University in Rome.

Digital radiography falls short in lung cancer screening trial
By
James Brice
While establishing the feasibility of digital radiography (DR) for lung cancer screening, a Dutch study has questioned the practicality of DR as a substitute for CT in detecting lung masses, according to a study published in the May issue of

CAD offers value in detecting pulmonary embolism
By
Erik L. Ridley
Computer-aided detection (CAD) technology can offer significant clinical value in diagnosing acute pulmonary embolism, if a recent study presented at the 2010 European Congress of Radiology in Vienna, Austria, is any indication.
