Iodine concentration measurements from DECT on an 86-year-old female subject with a Neer four-part proximal humerus fracture. The three planes of the right shoulder used for iodine concentration and humerus fragment measurements are shown: axial (a, b, g, h), coronal (c, d), sagittal (e, f). Areas were drawn in the humeral head fragment with overlying cartilage (a–f) and the glenoid vault (g, h) for iodine concentration measurement. The interfaces of the region with two energies (color, 100 and 140 kVp) and a single energy (no color, 140 kVp) is shown (thin arrows, c–f)
