    Differentiating between tumour progression and treatment-related abnormalities remains a challenge in brain tumour management.

  • 2

    Arterial spin labelling (ASL) MRI is a non-invasive technique that offers advantages over dynamic susceptibility contrast (DSC) MRI.

  • 3

    ASL perfusion measurements are based on endogenous blood water, avoiding issues related to blood-brain barrier leakage.

  • 4

    The study evaluates whether semiquantitative and visual assessments of ASL-PWI maps can replace quantitative ASL-CBF maps in clinical practice.

  • 5

    Findings suggest that ASL-PWI and ASL-CBF ratios are highly correlated, potentially simplifying ASL use in brain tumour surveillance.
