RT Journal Article SR Electronic T1 A Safe, Simple Method for Preparing Heat-Damaged Red Cells for Diagnosing Splenic Infarct or Trauma JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 204 OP 205 VO 26 IS 3 A1 Graeme M. Snowdon YR 1998 UL http://tech.snmjournals.org/content/26/3/204.abstract AB 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.
