    Spectral CT iodine quantification offers objective metrics for assessing peritoneal metastasis burden in ovarian cancer, addressing limitations of conventional CT.

  • 2

    In a study of 145 ovarian cancer patients, iodine-based parameters correlated strongly with intraoperative Peritoneal Cancer Index (PCI) values.

  • 3

    Normalized iodine concentration (NIC) effectively predicted complete cytoreduction (R0), achieving an AUC of 0.88 with a cutoff value of ≤0.55.

  • 4

    A combined predictive model using NIC, PCI, and CA-125 reached an AUC of 0.93, indicating excellent predictive capability for surgical outcomes.

  • 5

    The study suggests that spectral CT could enhance preoperative staging in ovarian cancer, though further external validation is necessary before clinical integration.
