    Contrast-enhanced thoracoabdominal CT is crucial for oncologic evaluation but poses risks of high radiation and contrast medium doses.

  • 2

    Photon-counting detectors (PCD) improve iodine contrast-to-noise ratio, potentially allowing for reduced contrast medium doses in CT imaging.

  • 3

    This study compares image quality and contrast enhancement in portal venous phase PCD-CT using 100 mL and 120 mL contrast volumes.

  • 4

    The study included 49 patients with known or suspected cancer, focusing on those who underwent specific contrast-enhanced CT scans.

  • 5

    Results indicated that PCD-CT with reduced contrast volumes maintains diagnostic quality, addressing concerns of over-enhancement.
