Indications for Use

The uPMR 790 system combines magnetic resonance diagnostic devices (MRDD) and Positron Emission Tomography (PET) scanners that provide registration and fusion of high resolution physiologic and anatomic information, acquired simultaneously and iso-centrically. The combined system maintains independent functionality of the MR and PET devices, allowing for single modality MR and/or PET imaging. The MR is intended to produce sagittal, transverse, coronal, and oblique cross sectional images, and spectroscopic images, and that display internal anatomical structure and/or function of the head, body and extremities. Contrast agents may be used depending on the region of interest of the scan. The PET provides distribution information of PET radiopharmaceuticals within the human body to assist healthcare providers in assessing the metabolic and physiological functions. The combined system utilizes the MR for radiation-free attenuation correction maps for PET studies. The system provides inherent anatomical reference for the fused PET and MR images due to precisely aligned MR and PET image coordinate systems.

Device Story

uPMR 790 is a combined 3.0T MRI and PET scanner; provides simultaneous, iso-centric acquisition of high-resolution metabolic (PET) and anatomic (MR) images. PET detectors integrated into MR bore. System includes superconducting magnet, RF coils, gradient coils, patient table, and software for scan control, image reconstruction, and management. Used in clinical settings by trained professionals. MR provides radiation-free attenuation correction maps for PET. New features include advanced pulse sequences (e.g., ASL, HISE), cardiac mapping, and AI-based PET attenuation correction (MRAC). Output consists of fused PET/MR images and spectroscopic data. Healthcare providers use these images to assess metabolic/physiological function and anatomical structure. Benefits include precise anatomical reference for PET studies and improved diagnostic information through simultaneous modality acquisition.

Clinical Evidence

No clinical trials were conducted. Evidence consists of non-clinical bench testing and performance evaluations. Performance of new features (ASL, cardiac mapping, spectroscopy, EasyScan/Plan) and PET/MR image quality was verified. AI-based MRAC performance was validated using a test cohort (n=27) independent of the training set (n=130); results showed average SUVmean error in major brain regions <3%, meeting the <10% acceptance criterion.

Technological Characteristics

3.0T superconducting magnet; 60cm bore; 45mT/m max gradient amplitude; 200T/m/s max slew rate; 48 receive channels. Conforms to NEMA MS 14-2019, NEMA NU 2, IEC 60601-1, IEC 60601-1-2, and IEC 60601-2-33. Biocompatibility per ISO 10993-5 and 10993-10. Software includes AI-based CNN for PET attenuation correction. Connectivity via DICOM standards.

Indications for Use

Indicated for patients requiring diagnostic imaging of the head, body, and extremities using simultaneous or independent MR and PET modalities to assess metabolic and physiological functions and internal anatomical structures.

Regulatory Classification
