NEVADA IMAGING CENTERS PERFORMS MORE THAN 3,500 PATIENT STUDIES USING THE WORLD’S FIRST DYNAMIC VOLUME CT — TOSHIBA’S Aquilion ONE

Versatile Imaging System Benefits Community By Offering Quick, Accurate Diagnosis

CHICAGO — December 1, 2008 — Demonstrating the strength and versatility of the world’s first dynamic volume CT system, Nevada Imaging Centers has provided more than 3,500 scans using Toshiba America Medical Systems, Inc.’s Aquilion® ONE dynamic volume CT scanner. Nevada Imaging Centers was the first facility in the western U.S. to install Toshiba’s new 320-detector row CT scanner. Toshiba will be showcasing the Aquilion ONE at this year’s Radiological Society of North America (RSNA) annual meeting in Chicago, Nov. 30 – Dec. 5, 2008 (Booth #3429, South Hall).

“The Aquilion ONE has empowered us to dramatically reduce diagnosis time and effectively serve a variety of patients while limiting the radiation dose,” said Dr. William W. Orrison, chief of Neuroradiology, Nevada Imaging Centers. “The Aquilion ONE provides a 4D image of a patient’s anatomy, including motion such as blood flow, which makes it ideal for imaging cardiology, neurology, vascular and orthopedic conditions.”

Dr. Orrison and Nevada Imaging Centers have diagnosed a variety of medical conditions. One example of when the Aquilion ONE expedited diagnosis was for a 77-year-old female patient suffering from continual headaches. After other imaging systems yielded equivocal results, Dr. Orrison conducted a brain perfusion study using the Aquilion ONE to uncover a region of the patient’s brain with decreased blood flow. This decreased blood flow would not have been detected without 16 cm of coverage provided by the 320-detector row CT system.

Introduced in November 2007, dynamic volume CT scans an entire organ in a single pass and produces 4D videos that show an organ’s structure, its movement and blood flow. In comparison, a 64-slice, 128-slice or 256-slice CT scan can only capture a portion of an organ in a single pass, requiring physicians to “stitch together” multiple scans of an organ to get a full image. The new technology helps reduce multiple exposures to radiation and exam time.

In addition, the Aquilion ONE’s single, comprehensive exam can provide physicians with data to replace a variety of duplicative tests and invasive procedures.

“Nevada Imaging Centers is at the forefront of demonstrating and exploring the versatility of the Aquilion ONE dynamic volume CT,” said Doug Ryan, senior director, CT Business Unit, Toshiba. “The Aquilion ONE’s ability to capture a 16 cm volume in one rotation and demonstrate the dynamic movement of that volume paves the way for multiple applications.”

With five locations throughout the greater Las Vegas community, Nevada Imaging Centers trains its board-certified radiologists on the latest technologies and best practices to assure its patients receive the best care possible. For more information, visitwww.nevadaimaging.com.
