We studied the reproducibility in vitro and in vivo of a new bone densitometer (HOLOGIC QDR-1000, software version 4.03) which uses an x-ray source at two different levels of energy. Short and long term coefficient of variation (c.v.) in vitro is less than 0.5%. In vivo c.v. is less than 1% in normal body weight subjects and less than 3% in obese subjects… CONTINUE READING
