Image Processing
Part III: Image processing has room to grow
The third and final installment of our series on 3D and virtual reality, based on presentations at the 2006 Computer Assisted Radiology and Surgery (CARS) meeting in Osaka, Japan, discusses the development of virtual reality imaging applications.

Instrumentation, attenuation correction steer nuclear cardiology's future
Nuclear cardiology modalities are seeing a resurgence of late, which is not to say the most widespread heart-imaging modalities were in decline. Still, recent technical improvements on multiple fronts, from detector technology to hybrid modalities like SPECT/CT and PET/CT, seem to have sharpened the modalities' future prospects as they have sharpened the images themselves.

New data reveal higher efficacy for primary VC screening
BOSTON - Across most of the U.S., virtual colonoscopy practice is a low-volume affair, relegated by lack of reimbursement to a few diagnostic indications and follow-up after incomplete colonoscopies. But clinicians and researchers at the University of Wisconsin Hospital and Clinics in Madison have built a bustling VC practice based primarily on reimbursed screening exams for mostly asymptomatic subjects 50 and older.

Time-resolved MRA effective for congenital heart defects
Improved imaging and therapeutic options have resulted in more congenital heart problems being diagnosed than in the past. Researchers in Germany believe they have found an easy, reliable way to deliver functional information in adult patients with complex congenital heart disease -- MRI.

Polyp surveillance risk may be acceptably low
BOSTON - Many gastroenterologists are uncomfortable with radiologists' practice of generally leaving medium-sized colonic polyps in the patient unless they grow larger than 10 mm. The studies, though few, suggest that the risks of surveillance may be acceptably low, and virtual colonoscopy researchers are conducting new studies to find out more.

CTA assesses traumatic neurovascular injury
In the setting of neurovascular trauma, CT's excellent image quality isn't enough to predict complications and manage patients optimally, particularly those who present with few or no neurological symptoms. New markers and tests may eventually improve the ability to predict complications. For now, careful attention to clinical and imaging data is key.

Advanced electronic cleansing preserves soft tissues in VC
A new electronic cleaning method goes beyond simple thresholding-based schemes for distinguishing tagged fluid and fecal material from polyps and folds in virtual colonoscopy. By analyzing the soft-tissue structures associated with submerged polyps and folds rather than just attenuation, the method yields significantly more accurate results with fewer false positives, both with and without CAD.
