New CAD algorithm picks out colorectal polyps
The first Hessian matrix-based computer-aided detection (CAD) algorithm for colorectal polyps yielded acceptable sensitivity and false-positive rates, according to researchers from Seoul, South Korea.

Hessian matrix-based CAD looks promising for VC
BERLIN - Virtual colonoscopy computer-aided detection (CAD) schemes based on the Hessian matrix method are gaining currency among researchers. At the 2007 Computer Assisted Radiology and Surgery (CARS) conference, researchers from Japan presented a CAD method that uses filters based on Hessian matrix eigenvalues to eliminate false-positive polyp candidates.

CARS news: USC group develops home-grown CAD-PACS integration toolkit
BERLIN - After two and a half years of sweating the details, a team led by researchers from the University of Southern California in Los Angeles say they have developed an easy method that PACS users can employ to incorporate CAD into their viewing workstations -- independent of the vendor they're using. The group presented its CAD-PACS toolkit at this week's Computer Assisted Radiology and Surgery (CARS) meeting.

CARS news: Automated device tracking beats conventional CT/US guidance
BERLIN - Automated tracking methods, used to guide biopsy needles, imaging probes, and ablation devices during interventional radiology procedures, have come a long way in a few short years. A presentation Wednesday during the opening day of the 2007 Computer Assisted Radiology and Surgery (CARS) conference featured a prototype navigation system that accurately evaluates electromagnetic tracking during soft-tissue ablation and biopsy procedures.

Fully automated VC CAD system solves tagging problems
Researchers from Massachusetts General Hospital in Boston have built a computer-aided detection (CAD) scheme that can find polyps in tagged virtual colonoscopy images, without getting bogged down by the oral contrast.

Patient survey suggests preference for minimal-prep VC
While colorectal cancer is the second leading cause of death in the U.S., less than half of screening age individuals over 50 are examined for the disease. A new survey suggests that eliminating the cathartic bowel preparation might improve compliance screening rates. But the answers may not predict patients' real interest in screening, and the minimal-prep approach is not without complications, cautioned a radiologist experienced in virtual colonoscopy screening.

Coronary CTA results correlate with all-cause mortality
Contrast-enhanced coronary CT angiography (CTA) is the new cardiac imaging test on the block. But does it offer a prognostic benefit? To start answering this question, researchers at the Weill Cornell College of Medicine in New York City examined more than 1,000 patients with chest pain or other symptoms suggestive of coronary artery disease using 64-detector-row CT angiography, and followed them over 15 months.

FDG uptake correlates with survival, biomarkers in NSCLC
Researchers have long sought early prognostic clues for lung cancer patients -- ideally signs that are early enough and robust enough to alter patient management. On both counts it appears that researchers from the Netherlands may be on to something. The group performed serial PET/CT scans in patients with non-small cell lung cancer (NSCLC). They found that the maximum uptake of FDG correlated not only with increased survival, but with two plasma biomarkers.

New progress in multiple myeloma treatment; MDCT has edge in detection
Multiple myeloma is slowly giving way to new drugs that are extending and improving the quality of patients' lives. Better treatment options make accurate evaluation all the more important for patient management. And according to a new study, multidetector-row CT (MDCT) detects multiple myelomas slightly better than MRI, and significantly better than PET. Neither MRI nor MDCT can do the job alone, however.
