New technology useful for soft-tissue imaging in interventional radiology procedures

07.05.2007
Soft-tissue cross-sectional imaging acquired on a flat panel C-arm fluoroscopic unit located in the interventional radiology area is feasible and useful for interventional radiology procedures, avoiding the necessity of sending patients out to a CT scanner, according to a new study by researchers from the Baptist Cardiac & Vascular Institute in Miami, FL.

For the study, 35 patient examinations were conducted, covering a diverse range of both vascular and non-vascular clinical application scenarios. The on-location imaging technique was used to evaluate arterial vessel characteristics such as thrombus, calcification, and size. Additionally, the technique was utilized in the evaluation of collections before and after drainage procedures. The researchers found that in 80% of the patients, additional clinical information was obtained that directly affected interventional therapy.

"This new imaging option allows for CT-like imaging from the acquisition of a rotational X-ray data set," said Constantino Pena, MD, lead author of the study. According to the researchers, the new technology has the possibility of making patient visits more efficient for both the doctor and the patient.

"Our report demonstrates that in selected cases the technique may be helpful in the care of patients. It gives the interventional radiologist the ability to acquire CT-like volumetric soft tissue images in the interventional suite without having to transport the patient to a CT scanner," said Dr. Pena.

The full results of this study will be presented as an electronic exhibit Monday, May 7 through Thursday May 10 during the American Roentgen Ray Society’s annual meeting in Orlando, FL.

Im Focus: Light-induced superconductivity under high pressure

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.

Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
