Performance Characteristics
An independent and prospectively planned clinical evaluation of PYLARIFY AI®

  • A high efficiency in producing quantitative (volumetric disease burden)
    structured report for PSMA PET/CT – median reading time 1.4
    minutes interquartile range 2.1 minutes.
  • A higher reproducibility of quantitative measurements compared to
    manual state of the art – ICC2 of three independent readers was
    observed at 98% when using PYLARIFY AI®, against 90% for manual
  • A better detection of lesions compared to manual state of the art – the
    pooled sensitivity of three independent readers was observed at 85%
    when using PYLARIFY AI®, against 84% for manual reads.

The user must ensure that the patient’s name, patient ID and study date displayed in the patient
section correspond to the patient case you intend to review.
The user must ensure the review of the image quality and quantification analysis results before
