Radiomics in PET/CT: Current Status and Future AI-Based Evolutions.

This short review aims at providing the readers with an update on the current status, as well as future perspectives in the quickly evolving field of radiomics applied to the field of PET/CT imaging. Numerous pitfalls have been identified in study design, data acquisition, segmentation, features calculation and modeling by the radiomics community, and these are often the same issues across all image modalities and clinical applications, however some of these are specific to PET/CT (and SPECT/CT) imaging and therefore the present paper focuses on those. In most cases, recommendations and potential methodological solutions do exist and should therefore be followed to improve the overall quality and reproducibility of published studies.

Can alternative PET reconstruction schemes improve the prognostic value of radiomic features in non-small cell lung cancer?

Purpose: To evaluate the potential benefit of using alternative reconstruction schemes of PET images for the prognostic value of radiomic features.

Methods: Patients (n=91) with non-small cell lung cancer were prospectively included. All had a PET/CT examination before treatment.
