Inter- and intraobserver variabilities of volume measurements were higher compared to the longest diameter measurement (p less then 0.001 for overall). Quantitative measurements were statistically different at less then 50% radiation dose levels for semi-automated measurements of the longest diameter, and at 25% radiation dose level for volumetric measurements. The variability related to radiation dose was not significantly different from the inter- and intraobserver variability for the measurements of the longest diameter. Conclusio
