From: Accuracy and precision of volumetric bone mineral density assessment using dual-source dual-energy versus quantitative CT: a phantom study

  CTDIvol (mGy) DLP (mGy × cm) kVp mAs
DECT 9.89 ± 0.33 198.54 ± 6.82 Tube A, 90; tube B, Sn150 180
QCT 12.41 ± 0.27 219.18 ± 8.69 120 180
  1. Mean CTDIvol and DLP values differed significantly between DECT and QCT (p < 0.001). Data are given as mean ± standard deviation
  2. CTDIvol Volumetric CT dose index, DLP Dose length product, DECT Dual-energy computed tomography, QCT Quantitative computed tomography
