Abstract
The influence of the fat content in the cancellous bone on CT [computed tomography] densitometry was measured on the excised vertebrae from 42 elderly human subjects. Using single energy CT, the decrease of the measured mineral content was 12% for a fat content of 10% by volume at a mean mineral content of 100-110 mg/cm3. Using a dual calibration at 85 and 130 kVp [kilovolt peak] with reference to K2HPO4 for mineral and to alcohol for fat, the mineral content of the vertebra can be measured with an accuracy of 6% referred to the ashweight.This publication has 1 reference indexed in Scilit:
