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.

CT lung screening gets boost by adding COPD sequence
By James Brice
Low-dose CT lung screening has already demonstrated its effectiveness in reducing mortality from lung cancer. Now, Dutch researchers have found that adding a short sequence to the low-dose CT protocol can help the modality detect chronic obstructive pulmonary disease (COPD), according to a study published on Tuesday in the Journal of the American Medical Association.

Reconstruction technique boosts lung CAD performance
By Erik L. Ridley
Adaptive statistical iterative reconstruction technology not only improves CT image quality but also increases the sensitivity of computer-aided detection (CAD) software for detecting lung nodules, according to an article published online in the European Journal of Radiology.

Novel x-ray computer model avoids need for repeat exposures
By Rebekah Moan
A digitally reconstructed radiograph computer algorithm has been produced -- and validated -- that adequately simulates anatomical and system noise. The image evaluators grade simulated chest x-rays at different exposure parameters to optimize radiographic technique for clinical computed radiography without repeat patient exposures.

Diffusion-weighted MRI identifies lung lesions
By AuntMinnieEurope.com staff writers
Diffusion-weighted MRI (DWI-MRI) scans proved to be more accurate than PET/CT scans in differentiating benign lung lesions from cancerous ones, according to a Belgian study presented at the European Respiratory Society Congress, which is being held in Amsterdam this week.

Watch out for lymph nodes on pediatric chest CT
By AuntMinnieEurope.com staff writers
The presence of lymph nodes on pediatric multidetector chest CT images are more common than a radiologist might expect due to the detection capabilities of contemporary CT scanners, concluded a study published online in European Radiology.

Researchers cut CT dose for nodule follow-up
By Eric Barnes
For surveillance of previously detected lung nodules, CT radiation dose can be cut to approximately 3% of the original exam dose, concludes a new study in the September edition of the American Journal of Roentgenology.

Lung cancer screening comes under the microscope
By Cynthia E. Keen
A plethora of clinical trials seeking answers about the value, impact, and effectiveness of lung cancer screening for individuals at risk are under way in Europe. By 2020, the data they generate will help determine the efficacy of making healthcare investments in low-dose CT screening.
