Colon CAD: VC's extra eyes face new challenges

By Eric Barnes

Prototype colon CAD systems are proliferating, and thanks to years of painstaking development work they're doing a pretty good job, outperforming all but the best radiologists in the detection of colonic lesions. VC CAD expert Dr. Hiro Yoshida from Harvard Medical School in Boston discusses the major innovations that have produced today's complex CAD systems, and the moving target CAD developers face in keeping up with new performance standards.

Model saves time, radiation by simulating anatomic changes during radiotherapy

By Eric Barnes

Organs and tumors can twist, turn, and deform substantially during radiotherapy, creating a moving target for treatment planners seeking to avoid irradiating normal tissue. One solution, a full CT scan before each treatment, is both time- and radiation-intensive. But what if doctors could simply "update" the pretreatment scan with a few newly acquired planar projection images? Researchers from Virginia built and tested a model to do just that.

Digital mammo with CAD requires sharp eye for false negatives

By Jonathan S. Batchelor

In the past few years, traditional film-screen and digital mammography has benefited by the application of computer-aided detection (CAD) software. Although studies have shown that CAD use can increase the detection of early-stage malignancies, radiologist experience is needed to reduce the number of false negatives to a minimum, according to researchers from Italy.

3D diminution index spots lung nodules attached to blood vessels

By Eric Barnes

BERLIN - A principal limitation of lung cancer imaging is the difficulty of distinguishing lung nodules attached to blood vessels from normal blood vessels, especially in CT data. But researchers from Japan have developed a 3D feature called the diminution index, which scans the CT pulmonary blood vessel data for signs of rapidly expanding shapes that can indicate a nodule rather than a blood vessel.
