Image postprocessing boosts performance of multidetector CT coronary angiography
By Erik L. Ridley
Interactive image display methods for multidetector CT coronary angiography exams yield higher diagnostic accuracy than prerendered images, according to an article in the June issue of Radiology. The research team sought to retrospectively evaluate the diagnostic accuracy of multidetector CT angiography in detecting significant stenoses using various image processing method.

Radiology still has a chance to control cardiac CT
By Cynthia E. Keen
In the decades-long struggle between radiologists and cardiologists over control of new cardiac imaging technologies, the heart specialists have an undefeated record. But history may not repeat itself with respect to cardiac CT angiography. In fact, the edge may be shifting to radiology, according to imaging utilization expert Dr. David C. Levin.

VC measurements more accurate than optical colonoscopy
By Eric Barnes
Virtual colonoscopy did a better job of measuring polyps than optical colonoscopy, and optimized 2D measurements were slightly more accurate than 3D, according to a just-published study from South Korea. The measurements affect not only thresholds for removal, but also polyp-matching algorithms in both modalities, explained the researchers from the Asan Medical Center and Seoul National University Hospital in Seoul.

Axial-loaded imaging of lumbar spine heightens diagnostic accuracy
MRI and CT allow clinicians to obtain sensitive 3D images of the spine, intervertebral disks, and neural structures, but both modalities have limitations when it comes to dynamic stress studies. Dr. Gerald Anzalone, a New York-based chiropractor, discusses how axial-loaded imaging can ramp up diagnostic specificity and enhance the visualization of dynamic spinal responses to compressive forces.

256-slice CT brings new possibilities in head imaging
By Eric Barnes
Researchers in Japan and the U.S. are producing promising new head CT images on a work-in-progress 256-slice scanner. A major advantage of so-called area detector scanning is the ability to acquire morphologic and functional images in a single scan, yielding a clutch of new diagnostic possibilities and time-saving exam protocols.

Study correlates CTA to angiography, myocardial perfusion SPECT
By Eric Barnes
An ambitious effort to compare the results of coronary CT angiography (CTA), catheter angiography, and myocardial perfusion SPECT imaging yielded good overall agreement in patients with known or suspected heart disease. The researchers, from the Medical University of South Carolina in Charleston, believe CT could potentially replace the other modalities in patients with known or suspected coronary artery disease.

Dual-source coronary CTA detects reduction in lumen diameter
By Paula Moyer
Even in patients with high heart rates, dual-source coronary CT angiography (CTA) provides accurate detection of significant lesions, according to a preliminary study by Dutch investigators. One reason for dual-source CTA's success is technical advancements in the equipment, said the group from Erasmus Medical Center in Rotterdam, Netherlands.

Big Japanese study finds benefit in CT lung screening
By Eric Barnes
SAN FRANCISCO - A lung cancer screening study of nearly 20,000 subjects in Japan found smaller tumors and improved survival rates with CT. Another study, from Oklahoma City, confirmed that CT-detected lung nodules that were stable over two years' time would remain benign.
