PET-CT Scanner

OU Medical Center uses the GE Discovery STE, the latest and most advanced PET/CT scanner available. Where other facilities in the state might have two or four slice CT units, the PET/CT scanner at OU Medical Center has a 16-slice CT. 

Compared to stand-alone PET, correcting for attenuation can be done much faster with the Discovery STE PET/CT scanner, which has a built-in 16-slice CT that creates a map of the patient attenuation. In addition, this brings more precision to lesion localization because of the combination of the metabolic PET image with an anatomic image from the CT.

Cancer & PET/CT

The GE Discovery ST is designed to help physicians diagnose and localize cancer faster than ever before, with its advanced technology that produces images that provide anatomic and metabolic information that result from a single exam in a single system.

Technical Information

GE's Discovery STE PET/CT scanner contains the ideal PET components that add up to optimized performance. It is the only detector optimized for both 3D and 2D imaging with full septa for optimal imaging of patients of all sizes. Isotropic crystal design also accurately shows lesion size and shape. It features thick 30-mm BGO detector crystals, selected for effectiveness with cancer radiotracers for the highest stopping power in the industry. Discovery STE's PET also contains square quad photomultiplier tubes specially engineered to boost the detector's efficiency at collecting image information significantly.

The Discovery STE also includes a full-featured GE LightSpeed 16-slice CT with attenuation correction - the best on the market for oncology and cardiovascular applications. It simultaneously acquires multiple adjacent slices of anatomy with solid-state GE HiLight Matrix detectors with high X-ray stopping power, low afterglow, z-axis uniformity and transparency. Its optimized image quality covers a full range of applications with speeds of up to 0.5 seconds and variable scan speeds adjustable in 0.1-second increments. It can also serve as a stand-along CT.
