Mean in-vivo CT Hounsfield density, SD, and 95% confidence interval for each histologic component*

Histologic ComponentMean (HU)SD (HU)95% Confidence Interval (HU)
Lipid-rich necrotic core32.620.0−7.472.5
Connective tissue46.419.96.686.2
  • Note:—HU indicates Hounsfield units.

  • * Determined by comparison of each 2 × 2-mm square electronically drawn on the in vivo CT reformatted images with corresponding histologic and micro-CT squares.
