    Dual-layer spectral CT (DLCT) can reduce radiation exposure by 39% compared to conventional CTP, benefiting patients needing repeated imaging.

  • 2

    DLCT-derived perfusion parameters show strong correlations with conventional CTP, indicating reliable estimation of cerebral blood flow and volume.

  • 3

    Iodine density maps from DLCT serve as static surrogates for CTP imaging, useful for patients where CTP is contraindicated or impractical.

  • 4

    DLCT allows simultaneous assessment of perfusion and vascular status, potentially streamlining clinical workflows in acute settings.

  • 5

    Further validation of DLCT-derived iodine maps is needed to establish their role as true surrogates for dynamic perfusion parameters.
