Swedes want to perform VC, but many lack equipment, training
May 8, 2006 -- Less than a quarter of Sweden's radiology departments perform virtual colonoscopy, but not for lack of interest in the procedure, a new study finds. Rather, the lack of multidetector CT scanners and training opportunities were the top reasons for not performing VC. Read More

VC CAD helps junior readers catch up
May 4, 2006 -- Virtual colonoscopy computer-aided detection (CAD) can improve sensitivity for polyp detection, especially for the inexperienced reader, according to a study from Paris. Read More

Austrian radiologist to lead 2007 ECR
March 8, 2006 -- VIENNA - The 2006 European Congress of Radiology (ECR) ended Tuesday with the installation of an Austrian radiologist to lead next year's proceedings, which will also highlight the imaging expertise of China and the Czech Republic. Read More

Professor Adam looks at ECR 2006 and beyond
March 2, 2006 -- As the curtain rises on the European Congress of Radiology (ECR 2006), AuntMinnie.com is pleased to bring you a conversation with this year's president, professor Andy Adam from the U.K. The professor of interventional radiology at King's College London talks about the meeting ahead, organizational changes in the ECR, interventional radiology, the National Health Service, and more in our exclusive interview.

Colon CAD: VC's extra eyes face new challenges
August 5, 2005 -- 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
July 25, 2005 -- 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. Read More

Digital mammo with CAD requires sharp eye for false negatives
June 30, 2005 -- 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.

CARS panel discusses the future of CAD
June 28, 2005 -- BERLIN - The potential of using computer-aided detection (CAD) as a diagnostic and clinical support tool in medicine has just begun to be discovered and commercially developed. Presentations at the two days of special sessions on CAD at the 2005 Computer Assisted Radiology and Surgery (CARS) meeting revealed that discovery and utilization are just the tip of the iceberg of possibilities.

Interventionalists see safer RFA with coregistered laparoscopic US, CT
June 27, 2005 -- BERLIN - Percutaneous radiofrequency ablation (RFA) and other minimally invasive interventions have become increasingly popular. But the interventionalists who perform them often end up working in the dark, as the CT or MR image they've placed across the room bears little resemblance to the laparoscopic ultrasound images used to guide the RFA needle. Researchers may have found a solution, according to a presentation at the Computer Assisted Radiology and Surgery (CARS) meeting. Read More

3D diminution index spots lung nodules attached to blood vessels
June 27, 2005 -- 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.
