FDG-PET/CT predicts radiation-induced lung toxicity
By AuntMinnie.com staff writers
FDG-PET/CT exams may be able to identify lung cancer patients who are highly susceptible to developing radiation-induced lung toxicity early during radiation therapy, according to researchers at the Maastricht University Medical Center in the Netherlands.

CARS report: New CAD tool follows lung nodules over time
By Eric Barnes
BERLIN - It's easy to complain about the insanity of tracking lung nodule changes in multiple CT scans over time, but at least one group is doing something about it, according to a presentation at the Computer Assisted Radiology and Surgery (CARS) meeting.

CAD for chest x-ray detects overlooked subtle lung cancer
By Cynthia E. Keen
Computer-aided detection (CAD) software found nearly half of all lung tumors missed by radiologists on their original interpretation of images, according to a study by University of Maryland researchers that's being published in the July issue of Radiology.

Dose can be reduced by 75% in pediatric chest CT exams
By Cynthia E. Keen
The radiation dose of pediatric MDCT exams can be reduced by as much as 75% without compromising the ability to detect small lung nodules in young children, according to a study published in the July issue of Academic Radiology.

New lung cancer staging guidelines reflect improved CT, survival data
By Eric Barnes
Lung cancer staging will undergo important changes following publication this year of the new edition of the tumor, node, and metastasis (TNM) classifications for lung cancer. Although much will improve compared to the current guidelines, thanks in large part to better data, important limitations will remain.

Homegrown software quantifies lymph nodes on CT scans
By Marty Graham
A group of Pennsylvania researchers has developed a software program that quantifies characteristics of lymph nodes in the mediastinum based on MDCT data. The researchers believe the software could eventually help stage lung cancer, according to a study presented at last week's American Thoracic Society meeting.

DR, film-based x-ray may vary in finding pneumoconiosis
By Brian Casey
A new study is highlighting the differences between digital radiography (DR) and conventional analog radiography in detecting abnormalities caused by dust-related lung diseases, or pneumoconiosis. The researchers say their work indicates that a commonly used classification system for pneumoconiosis should be updated to reflect the radiology community's increasing reliance on DR for chest imaging.

Audio and visual aids decrease radiation therapy treatment times
By Cynthia E. Keen
Use of respiratory-gating techniques during free breathing reduces healthy tissue exposure to radiation, but has the drawback of longer radiation therapy delivery times. Belgian researchers may have found a solution in an inexpensive, low-tech technique: At their center, visually guided voluntary breath-hold along with audio assistance reduced treatment time duration so that it's comparable to conventional treatment times.

CAD performs well in subsolid pulmonary nodules found with CT
By Erik L. Ridley
Computer-aided detection (CAD) technology can yield sensitivity gains for all pulmonary nodule types detected on CT scans, according to research presented at the recent American Roentgen Ray Society 2009 annual meeting in Boston.

CT-screened lung cancer patients live longer
By Eric Barnes
CT screening appears to find early-stage lung cancers that would not have been detected with chest x-ray, enabling CT-screened patients to live significantly longer, concludes a new study from Japan.

Two lung CAD systems unaffected by low dose
By Eric Barnes
A face-off between two lung nodule computer-aided detection (CAD) systems found a big difference in sensitivity for detecting solid pulmonary nodules, but it also revealed the good news that nodule detection was unaffected by low-dose scanning. The number of false positives also differed significantly between the two systems, researchers from Germany reported.
