Title: Quantitative Computed Tomography of the Lumbar Spine.
Abstract: Quantitative Computed Tomography (QCT) is one of the most successful method in determining bone mineral content of the spine.Lumbar mineral content of seventy-one patients (twenty-two cases were male and forty-nine were female) were determined by the QCT method. TCT 70-A CT and BMAS for the CaCO3 calibration phantom were used in QCT spine technique.Following results were obtained.1) Bone minerl contents of the lumbar spine decreased in the aged, especially in the females.2) Bone mineral contents in the cases of femoral neck fracture were less than those in the cases of trochanteric fractures, in the aged.
