Bundling of CAD software boosts lung lesion detection at CT
By Eric Barnes
Running CT lung images through multiple computer-aided detection (CAD) applications delivers better results than any single algorithm alone, researchers are finding. This phenomenon is unleashing a minitrend that may be discomforting to CAD developers concerned about the success of their systems.

PET/CT detects early efficacy of chemo drug in NSCLC patients
By Wayne Forrest
Dutch researchers have found that FDG-PET/CT can identify early response to preoperative chemotherapy with erlotinib in most patients with non-small cell lung cancer (NSCLC), according to a study in the September issue of the Journal of Nuclear Medicine.

FDG-PET before RT can modify planned NSCLC treatment
By Wayne Forrest
FDG-PET scans of non-small cell lung cancer (NSCLC) patients reviewed before radiation therapy (RT) may lead to significant changes in treatment strategy and radiation therapy planning, according to a study in the August issue of the American Journal of Roentgenology.

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.

Thoracic and abdominal aortic aneurysms often coexist
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 Annals of Surgery.

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 Academic Radiology.

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.
