- Deep Learning derived Input Function in dynamic PET

About the technology

With DLIF we present a non-invasive, automatically generated input-function for kinetic modelling in dynamic PET. Our deep learning models are trained end-to-end with dynamic PET images as input and ready-to-use input function as output. The model show very strong correlation and non-significant difference in influx (Ki) for myocardium and tumor derived with AIF and DLIF, respectively.

Value proposition

  • No surgery requirements
  • Compatible with any PET scanner and the most widely used tracers
  • Provides results that are highly accurate with less bias and variation than state of the art

Areas of application

  • Non-invasive input function for dynamic PET where blood sampling is not possible
  • Preclinical or clinical applications
  • Could be integrated into external software independent of PET scanner vendor
  • As a part of the PET scanner-software to deliver the DLIF together with the PET images

Resources and partners

  • The Norwegian Nuclear Medicine Consortium 180°N
  • Tromsø Research Foundation ​
  • Centre for Research-based Innovation (SFI) Visual Intelligence
  • Proof of concept validated for small scale research in mice
