To determine whether quantitative bone scintigraphy (QBS) with single-energy photon emission computed tomography (SPECT) can help predict which patients with chronic renal disease will show bone mineral density (BMD) loss.
In 18 patients, the percentage of injected dose of technetium-99m methylene diphosphonate per cubic centimeter of bone was measured with QBS SPECT in the lumbar vertebrae and femoral neck. The differences in BMD over an average of 20 months were measured and compared with SPECT measurements. QBS values were also compared with serum bone turnover markers.
There was a negative correlation (r = -.54, P < .05 for the lumbar spine and r = -.60, P < .01 for the femoral neck) between QBS values and bone loss. Positive and negative predictive values, sensitivity, and specificity of QBS for bone loss in the lumbar spine were 78%, 71%, 78%, and 71%, respectively, and in the femoral neck, 82%, 100%, 100%, and 78%, respectively. Differences between predictive values of serum bone turnover markers were not statistically significant.
QBS with SPECT enabled prediction of rapid bone loss in patients with renal disease.
