CARS panel discusses the future of CAD

By Cynthia E. Keen

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

By Eric Barnes

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

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.

4D MRI enables blood-velocity measurement in mitral valve insufficiency

By Eric Barnes

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 opens with call for more PACS research

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).

CARS suite of the future sees key role for image-guided intervention

By Eric Barnes

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.

Radiology workstations need integration, automation

By Erik L. Ridley

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.

Researchers take aim at next-generation image-guided surgery systems

By Eric Barnes

Just as virtual guided imaging is beginning to pay off in diagnostics, a group of techno-wizards have taken aim at the next goal: putting powerful, intuitive, real-time image guidance systems into surgeons' hands.

Finnish team searches for better mammography CAD system

By Shalmali Pal

SAN FRANCISCO - A fully automated computer-aided diagnosis (CAD) system that provides differential diagnosis for breast calcifications may prove superior to neural network-based CAD systems, but must face down several challenges before it can move past the conceptual phase, according to its Finnish designers.
