PET/MR performs well in assessing pulmonary masses
By Erik L. Ridley
VIENNA - PET/MR is a feasible technique that yields diagnostic image quality in evaluating lung masses, according to results presented at a Monday scientific session of the European Congress of Radiology.

Low-dose MBIR beats ASIR recon in most image-quality categories
By Eric Barnes
VIENNA - The new model-based iterative reconstruction (MBIR) technique handily outperformed adaptive statistical iterative reconstruction (ASIR) in one of the first head-to-head series, researchers reported on Saturday at the European Congress of Radiology.

Keep aware of lung nodules to avoid malpractice claims
By Philip Ward
VIENNA - CT plays a critical role as an imaging biomarker for pulmonary nodules, and it can also help determine patient management, according to Dr. Cornelia Schaefer-Prokop, associate professor of radiology at Meander Medical Center, Amersfoort, the Netherlands.

CT perfusion plus PET/CT aids lung cancer diagnosis
By Eric Barnes
Adding CT perfusion scans to routine PET/CT offers critical new information about tumor viability that can improve staging and management noninvasively in patients with suspected lung cancer, according to a study from Italy.

'Virtual phantom' helps guide dose reduction in CR studies
By Rebekah Moan
U.K. researchers have developed a computer-based simulator for estimating radiation dose in computed radiography (CR) studies. The researchers believe their "virtual phantom" could prove more effective than physical phantoms by enabling clinicians to gauge the impact of patient anatomy when imaging parameters are changed.

Post-op rad therapy unneeded for elderly lung cancer patients
By Cynthia E. Keen
Patients who have undergone surgery to resect stage III non-small cell lung cancer with N2 lymph node involvement may not need postoperative radiation therapy if they are older than 65, as the treatment doesn't help survival, according to an article published online February 13 in Cancer.

Follow-up protocol performs well in CT lung screening
By Eric Barnes
Swiss researchers have reported good results with a protocol for working up patients with nodules found on CT lung screening, according to an article in the February issue of the American Journal of Roentgenology. The algorithm produced low false-positive rates, and could make the establishment of large-scale CT screening programs more feasible.

MRI lung perfusion looks set for broader clinical use
By Wayne Forrest
Contrast-enhanced MRI pulmonary perfusion should be used in a broader clinical area, in part because the modality can be performed quickly, even in critically ill patients, but optimal temporal resolution and contrast-to-noise ratio are both necessary to achieve appropriate perfusion imaging of the lung, according to researchers.

Digital tomosynthesis may have role in lung cancer screening
By Rebekah Moan
Digital chest tomosynthesis may be a promising first-line tool for lung cancer screening, a preliminary study out of Italy shows. Using the modality with a digital radiography system detected noncalcified nodules in a percentage comparable with CT scans in previous studies.

DR chest tomosynthesis helps characterize lung lesions
By Rebekah Moan
The use of chest tomosynthesis with a digital radiography (DR) system enabled radiologists to characterize pulmonary lesions, circumventing the need for further diagnostic workup of patients with CT, according to a study by Italian researchers.

DR chest tomo reduces number of CT exams in Sweden
By Rebekah Moan
Using chest tomosynthesis with a digital radiography system reduced the number of chest CT exams performed at a Swedish institution, leading to lower radiation dose and better use of CT resources, according to a presentation from last week's RSNA meeting.

Automated calcium scoring fits well with lung cancer screening
By Erik L. Ridley
Coronary calcium scoring with an automated technique fits well in a lung cancer screening setting, enabling cardiovascular risk assessment in a population potentially at high risk of cardiac events, according to a Dutch study presented at the RSNA 2011 meeting.
