CAD shines in detecting large nonsolid pulmonary nodules
By Cynthia E. Keen
Computer-aided detection (CAD) software can outperform both a senior thoracic radiologist and a resident trained in chest imaging for detecting nonsolid pulmonary nodules larger than 3 mm, according to a study from France. The results support the use of a CAD system as a second observer for both nonsolid and solid nodules detected on CT studies, the researchers said.

Inversion-recovery MRI falls short in brain tumor detection
By Shalmali Pal
Inversion-recovery (IR) imaging has made significant strides in brain MR, offering higher T1-weighted contrast and improving the contrast ratio of tumor to white matter. But IR imaging still cannot best spin-echo (SE) MRI for detecting brain metastases, according to radiologists from China. They compared the two MR protocols in 31 patients treated at the First Affiliated Hospital of Anhui Medical University in Hefei.

Researchers from Duke University Medical Center in Durham, NC, have recently found that the radiation dose of pediatric thoracic CT scans can be cut by more than half using breast shields with dose modulation software.

Multimodality studies tackle benign but evasive nerve-sheath tumors
By Shalmali Pal

But making the all-important differential diagnosis isn't easy with either approach. Which imaging modality is up to the task? Musculoskeletal experts in Taiwan explored the role of ultrasound, while a group from the U.S. laid out the imaging appearance of these nerve-sheath tumors.
