The PennPET Explorer PET system is a diagnostic imaging device that, together with the co-located IQon CT scanner, combines Positron Emission Tomography (PET) and X-ray Computed Tomography (CT) systems. The IQon CT system images anatomical cross-sections by computer reconstruction of X-ray transmission data. The PET system images the distribution of PET anatomy-specific radiopharmaceuticals in the patient. Together, these systems are used for the purposes of detecting, localizing, diagnosing, staging, re-staging, and follow-up for monitoring therapy response of various diseases in oncology, cardiology, and neurology.
The system is intended to image the whole body, heart, brain, lung, gastrointestinal, bone, lymphatic, and other major organs for a wide range of patient types, sizes, and extent of diseases. The CT scanner can also be operated as fully functional, independent diagnostic tool, including for use in radiation therapy planning.
Indications for use as stated in the FDA summary.
