Premarket evidence — what FDA accepted

Device typesamd

source quote (p.10)

“aPROMISE consists entirely of software; accordingly, there are no sterilization concerns. As a software only device, shelf-life (including performance date) is also not applicable because of low likelihood of time-dependent product degradation.”

AlgorithmAI enabled automated segmentation of skeleton and soft tissue organs; algorithm to detect high intensity regions of interest in the PET series within the segmented structures (skeleton and soft tissue).

Bench

sample size not stated

endpoints: accuracy; linearity; limit of detection

Bench

sample size not stated

endpoints: equivalent performance for standard functions in marking and quantitative assessments of user defined region of interest

Retrospective clinical

sample size not stated

endpoints: automated quantification of tracer uptake in reference organs that are more reproducible, and consistent than those obtained manually; high sensitivity in pre-selection of regions of interest that are determined to be suspicious for metastatic disease

Reported performance (0 observations)

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