    CT numbers are essential for diagnostics, disease tracking, and quantifying elements like calcium and iodine in tissues.

  • 2

    Misinterpretations of CT numbers can lead to significant errors in quantifying elements like hydroxyapatite and iodine.

  • 3

    CT numbers are only proportional to element mass when the background material is pure water, not in vivo.

  • 4

    Iodine-water material decomposition is inaccurate in vivo, leading to quantification errors.

  • 5

    Understanding the limitations of CT number assumptions is crucial for accurate material quantification in clinical settings.
