    Dual-energy CT (DECT) shows non-inferior diagnostic performance compared to conventional triphasic CT in gastrointestinal bleeding.

  • 2

    The study included 100 patients, with 50 having active GI bleeding and 50 matched controls without bleeding.

  • 3

    Reading times and diagnostic confidence were also found to be non-inferior when using the DECT protocol.

  • 4

    DECT may reduce radiation exposure by eliminating true non-contrast scans while maintaining diagnostic efficacy.

  • 5

    Current guidelines recommend using DECT-derived virtual non-contrast images for suspected upper GI bleeding.
