Eric Barnes[email protected]Clinical NewsModel saves time, radiation by simulating anatomic changes during radiotherapyOrgans 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.July 24, 2005Clinical NewsInterventionalists see safer RFA with coregistered laparoscopic US, CTBERLIN - 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.June 26, 2005Clinical News3D diminution index spots lung nodules attached to blood vesselsBERLIN - 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.June 26, 2005Clinical News4D MRI enables blood-velocity measurement in mitral valve insufficiencyBERLIN - 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.June 23, 2005Clinical NewsCARS suite of the future sees key role for image-guided interventionBERLIN - 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.June 22, 2005Clinical NewsNanotechnology and new horizons: A talk with the president of ECR 2005We are pleased to present our annual interview, and our first bilingual interview, with the president of the European Congress of Radiology.
