Premarket evidence — what FDA accepted

Device typehardware with ml
source quote (p.5)
The proposed device uMI Panvivo combines a 295/235/534/712 mm axial field of view (FOV) PET and 160-slice CT system to provide high quality functional and anatomical images, fast PET/CT imaging and better patient experience.
Algorithmdeep learning-based PET reconstruction algorithm, pre-trained neural networks to reduce metal artifacts, and motion correction techniques
source quote (p.15)
uExcel DPR (Deep Progressive Reconstruction) is a deep learning-based PET reconstruction algorithm. It utilizes pre-trained deep neural networks on long-axis datasets to optimize the iterative reconstruction process, effectively reducing noise and improving contrast.

Validation studies (5)

Reader study (MRMC)

n=20 patients

endpoints: average CT value in the affected area of the metal substance; tissue interpretability; metal artifacts correction

Reader study (MRMC)

n=8 patients

endpoints: Contrast recovery (CR); background variability (BV); contrast-to-noise ratio (CNR); liver signal-to-noise ratio (liverSNR); visual assessments

standards: NEMA NU 2-2018

Reader study (MRMC)

n=13 patients

endpoints: Volume relative to no respiratory motion correction (∆Volume); Maximal standardized uptake value relative to no respiratory motion correction (∆SUVmax); respiratory motion artifacts; PET/CT alignment accuracy; diagnostic confidence

Reader study (MRMC)

n=7 patients

endpoints: ∆SUVmean in the high-uptake region; head motion artifacts; image quality; diagnostic confidence

Reader study (MRMC)

n=4 patients

endpoints: image Artifacts; homogeneity of same tissue; diagnostic confidence in PET images; accuracy of CT value; accuracy and uniformity of PET image SUV

Reported performance (0 observations)

FDA source did not state a quantitative performance metric — non-reporting is itself the signal.

Each value carries its own analysis unit and task — never compare or pool across devices. Source: 510(k) summary PDF.
