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.
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.
4D MRI enables blood-velocity measurement in mitral valve insufficiency June 24, 2005 -- BERLIN - Mitral valve insufficiency is a fairly common heart problem that lacks ideal imaging solutions. The problem lies in assessing regurgitant blood flow to determine the need for intervention. A presentation Thursday at the Computer Assisted Radiology and Surgery (CARS) meeting discussed the limitations in assessing blood flow, and highlighted a new measurement approach using time-resolved MRI vector fields.
CARS suite of the future sees key role for image-guided intervention June 23, 2005 -- BERLIN - In Wednesday's opening session of the 19th International Congress of Computer Assisted Radiology and Surgery (CARS), Dr. Michael Vannier set forth his vision of the interventional suite of the future, and touched on the powerful forces shaping its development.
CARS opens with call for more PACS research June 23, 2005 -- BERLIN - After 23 years of academic research and commercial evolution into a clinically viable technology, does PACS merit another decade of additional R&D by the medical academic community? Dr. Davide Caramella, president of EuroPACS, addressed this question during a presentation Wednesday at the International Congress of Computer Assisted Radiology and Surgery (CARS).
View from the president: Professor Helen Carty scans ECR 2004 March 4, 2004 -- As ECR 2004 begins, AuntMinnie.com is pleased to present an in-depth interview with this year's president, Professor Helen Carty. She is a senior member of the Royal College of Radiologists, a consultant radiologist at the Royal Liverpool Children’s Hospital, Alder Hey, and professor of pediatric radiology at the University of Liverpool in the U.K.
Radiology workstations need integration, automation March 15, 2002 -- SAN ANTONIO - Diagnostic radiology workstations have come a long way from the early days of PACS. But further progress can still be made, said Dr. Steven Horii in a presentation at the "PACS 2002: Implementing CR/DR and Integrating the Healthcare Enterprise" conference.
