VMI at the range of 40–150 keV (a–l, 10-keV interval) scanned after administration of iodinated contrast. The patient presented with an osteomyelitis of the mandible and cutaneous fistula (see also Fig. 12). Iodine conspicuity was increased at lower keV, as can be noticed by the increased CNR around the vessels (arrow). Higher-energy VMI results in an increase in signal-to-noise (SNR) and a decrease in streak artifacts caused by metallic hardware
