Abstract
Objective: The purpose of this study was to demonstrate a fast, safe and simple method for preparing heat-damaged red blood cells.
Methods: Patient blood was radiolabeled using the Ultra-Tag® RBC kit and then heated to 49.5°C for 20 min. The reaction vial was cooled in ice water for 1 min and the required activity was administered to the patient. The patient was imaged 60 min postinjection.
Results: High-quality planar and SPECT images of the spleen were obtained with low background activity noted. Radiolabeling efficiency was greater than 95%.
Conclusion: The method was safe and simple to perform. High-quality images of the spleen were obtained.
