FDG-PET/CT predicts radiation-induced lung toxicity
By AuntMinnieEurope.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.

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.

Stereotactic body radiation slows lung cancer
By Reuters Health
NEW YORK (Reuters Health), May 22 - Stereotactic body radiation therapy appears to be highly effective for treating certain patients with non-small cell lung cancer, providing a three-year local tumor control rate of 90% or higher with minor toxicity, Scandinavian researchers report in a May 4 online edition of the Journal of Clinical Oncology.

CT screening has little effect on smoking habits
By Reuters Health
NEW YORK (Reuters Health), May 22 - The results of a study published in the May issue of Thorax suggest that CT screening has little effect on the smoking habits of patients at one-year follow-up compared with smokers who do not undergo screening. CT screening neither induces more smoking nor promotes cessation, the researchers conclude.

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.

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.

Cancer cure rates on the rise in Europe: study
By Reuters Health
LONDON (Reuters), Mar 24 - More Europeans are beating cancer, perhaps due to more widespread screening and earlier diagnosis, according to a study published on Tuesday.

NELSON lung cancer trial yields positive early results
By Eric Barnes
VIENNA - A first peek at the first results of the first large randomized lung cancer screening trial to near completion found that CT detected four-fifths of participants' lung cancers at stage I -- in time to effect a curative resection.

CT protocols reduce risk for pulmonary embolism
By Rob Skelding
VIENNA - New research presented at the 2009 European Congress of Radiology examines whether reduced-energy CT and low-dose contrast media provide safer solutions without compromising pulmonary embolism image quality.

Integrating lung CAD with PACS boosts utilization
By Erik L. Ridley
VIENNA - Integrating computer-aided detection (CAD) technology into PACS workstations can dramatically boost its usage for detecting pulmonary nodules on MDCT studies, according to research from the University of Munich in Germany.

Italian study backs tomosynthesis over DR for lung pathology
By Brian Casey
A study by Italian researchers has added to the growing body of evidence indicating that digital radiography (DR) with a tomosynthesis capability is superior to conventional DR in detecting pulmonary alterations that could be signs of lung pathology. But tomosynthesis wasn't totally without drawbacks.
