New computed tomography ( CT ) scanner that provides physicians with precise images of internal organs with a single rotation of the gantry is now in operation at SBUMC.

A new state-of-the art computed tomography (CT) scanner that provides physicians with precise images of internal organs with a single rotation of the gantry is now in operation at Stony Brook University Medical Center (SBUMC), adding to the hospital’s advanced scanner technology.

The Toshiba Aquilion ONE \320-detector row CT system with pediatric imaging capabilities is able to image an entire organ in a single rotation or over multiple rotations, showing real-time dynamic movement. The single rotation will result in lower doses of radiation, which is particularly important for children and teens, who are still developing.

A typical CT scan exposes patients to the radiation equivalent of 200 x-rays. Dr. Poon has performed more than 1,000 cardiac CTA’s ( CT angiographies ) within the past year at SBUMC and used the low-dose radiation technique for the first time on two pediatric patients.

The new CT scanner will allow physicians to see not only a three-dimensional depiction of an organ, but also how the organ and blood flow are dynamically functioning or moving within and around the organ. No other CT system can do this. The Aquilion ONE can perform uniquely comprehensive exams, including functional studies, that can reduce overall healthcare costs by replacing the need for multiple tests and invasive procedures, while reducing the amount of contrast material and radiation dose. Additionally, multi-phase studies, such as perfusion of the brain, heart and other organs, are possible with the Aquilion ONE .

CT technology enables Dr. Poon and colleagues to view the entire structure of heart, the internal and external features, including the coronary vessels and structural components inside the heart, in order to diagnose cardiac disease or rule it out. The procedure is non-invasive, often leads to a definitive diagnosis, and prevents some patients from further non-invasive and invasive testings such as nuclear stress test, cardiac catheterization or coronary stenting.
