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.

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.
