Researchers make inroads with breast CT, gear up for clinical test

By Shalmali Pal

Thirty years after breast CT was introduced, abandoned, and then reintroduced, California researchers believe they have a viable breast CT unit that may detect tumors sooner than mammography. The group presented the results of their most recent research Sunday at the American Association of Physicists in Medicine (AAPM) meeting in Seattle.

MR, CT best to evaluate early tibial stress injury

By N. Shivapriya

MRI is the best technique to assess early tibial stress injury, but CT is the method of choice for detecting osteopenia, an early sign of fatigue damage of the cortical bone, according to a recent study by Italian researchers.

VC holds up against back-to-back colonoscopies

Virtual colonoscopy's accuracy is hard to verify because it is usually compared against the imperfect gold standard of optical colonoscopy. But in a new study, researchers in Italy compared the results of VC to those of back-to-back colonoscopies and may have achieved the best reference standard so far for VC.

Reduced prep, low-residue diet, and mild tagging suffice for accurate VC

High barium doses aren't necessary for reduced-prep virtual colonoscopy when a low-residue diet is part of the protocol. In the American Journal of Roentgenology, researchers from Belgium reported high sensitivity and specificity for colorectal polyps using such a protocol.

Gadolinium effective in CTA of pulmonary circulation

By N. Shivapriya

Gadolinium-based contrast agents, usually reserved for MR imaging, can provide diagnostic CT angiograms of pulmonary circulation with 16-detector-row CT, and can be used as an alternative to iodinated contrast in patients with contraindications for iodinated agents, according to researchers from France.

Lung PET rules when CT is equivocal, discordant

Although PET's high cost ensures that CT and radiography will remain the first-line lung cancer detection modalities for at least the near future, PET can be very useful adjunctively in patients whose diagnosis remains uncertain in the light of available radiographic and clinical evidence.

3D navigation holds promise for image overload

By Jonathan S. Batchelor

The evolution of modalities used in the practice of radiology is fast producing a daily volume of images that threatens to overload the capacity of interpreting radiologists. But strategies for handling the increased workflow, such as the use of volumetric navigation, continue to evolve as well, according to a presentation at the Society for Computer Applications in Radiology (SCAR) meeting.
