Quantitive Computed Tomography of The Lumbar Spine

Quantitive Computed Tomography (QCT) is one of the most successful method in determining bone mineral content of the spine.Lumbar mineral contents of one hundred patients (thirty-one males and sixty-nine females) were determined by the QCT method.Following results were obtained.1) In the female patients, bone mineral content of the lumbar spine severely decreased to marginal value of abnormality, boundary of their anomeria.2) Bone mineral contents of the cases of trochanteric fractures were less than the cases of femoral neck fracture.3) The results of QCT method were related to the classification system on plain x-ray photographs.
