Intended Use

The uMI Panvivo is a PET/CT system designed for providing anatomical and functional images. The PET provides the distribution of specific radiopharmaceuticals. CT provides diagnostic tomographic anatomical information as well as photon attenuation information for the scanned region. PET and CT scans can be performed separately. The system is intended for assessing metabolic (molecular) and physiologic functions in various parts of the body, including whole body, brain, head and neck, heart, lung, breast, gastrointestinal, urinary system and genital organ, musculoskeletal systems, and others. When used with radiopharmaceuticals approved by the regulatory authority in the country of use, the uMI Panvivo generates images depicting the distribution of these radiopharmaceuticals. The images can serve as an aid in detection, localization, evaluation, diagnosis, staging, re-staging, monitoring, and/or follow-up of abnormalities, lesions, tumors, inflammation, infection, organ function, disorders, and/or diseases, in clinical areas such as oncology, infection and inflammation, and neurology. The CT system can be used for low dose CT lung cancer screening for early detection of lung nodules that may represent cancer.

Technology

The device combines a PET system with a 235/295 mm axial field of view and a 160-slice CT system. It includes PET and CT detectors (scintillator LYSO), a patient table, power distribution unit, control and reconstruction system (host, monitor, reconstruction computers, system and reconstruction software), and vital sign monitoring module. PET and CT imaging can be performed separately or combined. The system uses scalable PET rings with the proposed uMI Panvivo S model having 80 PET rings compared to 100 rings in the predicate uMI Panvivo. The CT component is a uCT 780 system. The uMI Panvivo technology maintains the same basic operating principles and fundamental technologies as its predicate device

Performance

Non-clinical testing verified that the device meets all design specifications and is substantially equivalent to the predicate device. Sample clinical images reviewed by US board-certified radiologists confirmed that the device generates images as intended with sufficient diagnostic quality. The device complies with multiple electrical safety, EMC, biocompatibility, and software standards to ensure safety and effectiveness.
