Effect of Diagnostic Radioisotopes and Radiographic Contrast Media on Measurements of Lumbar Spine Bone Mineral Density and Body Composition by Dual-Energy X-Ray Absorptiometry

Since there is almost no information on whether the concomitant use of diagnostic radioisotopes and radiographic contrast media interferes with dual-energy X-ray absorptiometry (DXA), we investigated these potentially confounding effects. At routine scheduled radiographic follow-up, 40 patients previously treated for malignant lymphomas or solid tumors in Hamilton and Ottawa, Canada were evaluated, 10 in each of the following 4 categories of …
