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.

Radiosurgery advised for postpneumonectomy recurrent lung cancer
By Cynthia E. Keen
A large study of patients who developed contralateral lung cancer after having a pneumonectomy suggests that stereotactic radiation therapy is a curative option with minimal toxicity, even for high-risk patients with chronic obstructive pulmonary disease.

Study calculates radiation dose risk for infants in Belgian NICU
By Cynthia E. Keen
A Belgian study has shed additional light on the amount of radiation dose delivered to infants in neonatal intensive care units (NICUs). The research provides reference values for NICU radiation dose, and also offers guidance on collecting dose measurements and converting them into organ-dose values.

Adding CsI-based dual-energy imaging doesn't improve lung nodule detection
By Radiology Review
(Radiology Review) New research suggests that cesium iodide (CsI) detector-based dual-exposure dual-energy imaging, when added to chest radiography, does not significantly improve the detection or classification of pulmonary nodules.

MIP boosts detection of small pulmonary nodules
By Erik L. Ridley
CHICAGO - Performing maximum intensity projection (MIP) reformatting of MDCT studies adds significant utility for finding pulmonary nodules less than 10 mm in size, according to research from the University Medical Center Hamburg-Eppendorf in Hamburg, Germany.
