Abstract
Purpose: To determine whether dynamic registration at bone and bone-marrow scintigraphy produces additional information compared to subsequent static registrations of bone-marrow transplants in multiple myeloma patients.
Material and Methods: In a prospective study, 8 dynamic bone and 6 dynamic bone-marrow scintigraphies were performed in 10 patients. The dynamic scintigraphies were compared with conventional radiography, MR images, and static scintigraphies of bone and bone marrow.
Results: No additional information was revealed by the dynamic registration method; on the contrary, 4 of the 8 known lesions were not discerned at dynamic registration. An incidental observation was that the time-activity curves of both radiopharmaceuticals had a specific pattern.
Conclusion: Dynamic registration at bone and bone-marrow scintigraphy was not useful for detecting disease in multiple myeloma lesions.
