UPTAKE OF STRONTIUM-85 IN NON-MALIGNANT VERTEBRAL LESIONS IN MAN
By means of external scintillation counting, it was possible to demonstrate abnormally high spinal uptake of intravenously injected Sr/sup 85/ in various diseases of the vertebral column. A total dose of 50 mu c carrier-free Sr/sup 85/ was injected 7 to 14 days before recording spinal radioactivity with a collimated scintillation detector. An abnormal activity pattern was defined as a deviation from the normal pattern of twice the standard deviation of the normal mean value. Abnormal spinal patterns were detected in vertebral fractures, ankylosing spondylitis, tuberculous spondylitis, nonspecific discitis, and in a case with a lytic lesion of unknown origin. The value of 14 days was found more reliable than that at 7 days since by this time Sr/sup 85/ levels in soft tissues had fallen to low values. In 1 case, erroneous results were obtained from spinal counting due to a kidney stone which produced high activity in the spinal region. (H.H.D.)
