Arkansas Children's Hospital has installed Toshiba America Medical Systems, Inc.'s Aquilion ONE 320-detector row CT system. As the world's first dynamic volume CT scanner, the Aquilion ONE can lower radiation dose, which is particularly important when imaging pediatric patients. As the first pediatric facility to install the Aquilion ONE, Arkansas Children's Hospital selected dynamic volume CT for its ability to significantly lower patient radiation dose exposure and decrease the sedation needed for exams. Traditionally, when children are imaged using multi-detector CT, sedation is frequently required to keep the patient still long enough to obtain a clear diagnostic image. The Aquilion ONE's fast exam time, which captures up to 16 cm of an anatomical region in one rotation, means that less patient sedation is required. The Aquilion ONE will be used to serve the facility's primarily pediatric patients in multiple settings, including cardiology, orthopedics and neurology. The facility also plans to use the Aquilion ONE in new dynamic studies focused on joint and respiratory issues and to develop new pediatric protocols to continue to increase pediatric safety in CT imaging. "The ability to image pediatric patients with reduced radiation and no sedation will greatly benefit our patient community," said Dr. Bruce Greenberg, professor of radiology, Arkansas Children's Hospital, University of Arkansas for Medical Sciences. "Technology like the Aquilion ONE continues to help us deliver the best possible care to patients while keeping patient safety at the forefront." The Aquilion ONE features Toshiba's SUREExposure Pediatric software, which automatically measures the size and age of each patient and tailors radiation dose to achieve the best and safest image quality for each exam. The software uses protocols selected based upon the patient's age, size and type of exam to ensure patients receive only the radiation required to obtain a clear diagnostic image. SUREExposure Pediatric software comes standard on all Aquilion products. "The Aquilion ONE's ability to reduce radiation and capture images with significantly less pediatric sedation makes it an ideal addition to this facility," said Doug Ryan, senior director, CT Business Unit, Toshiba. "Arkansas Children's Hospital is the first US pediatric hospital to use the Aquilion ONE with advanced dynamic volume CT protocols that will continue to make imaging safer for all patients — especially children." Introduced in November 2007, this advanced system 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, forcing 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.
