    The study proposes a fully automated method for quantifying net water uptake (NWU) in acute ischemic stroke using only non-contrast CT imaging.

  • 2

    Current NWU calculations rely on multiple imaging modalities, making them time-consuming and operator-dependent, highlighting the need for a streamlined approach.

  • 3

    The proposed method integrates expert knowledge with heuristics, avoiding deep learning to ensure interpretability and reduce the risk of overfitting.

  • 4

    Validation of the automated NWU quantification was conducted on an in-house dataset of 155 patients and an external dataset of 46 patients.

  • 5

    Results indicate that NWU can be effectively computed from NCCT images alone, offering a practical alternative to conventional stroke assessment methods.
