مستخلص: Purpose: To measure the decay activity loss and delivery system residual activity loss of yttrium-90 (Y 90 ) radioembolization treatments across resin and glass microsphere activities.
Materials and Methods: For Y 90 administrations between December 2009 and June 2017 at the study institution, the prescribed activity, prepared activity, and delivered activity were recorded. Six hundred sixty-two administrations were reviewed-345 glass (0.21-8.52 GBq) and 317 resin (0.18-3.28 GBq). Twenty-five patients (all resin) were excluded for arterial stasis or catheter clogging. The percentage and actual losses of activity lost to decay and to delivery system residual were calculated for glass and resin microspheres.
Results: The median time between activity premeasurement and administration was 2.20 hours, resulting in a median activity lost to decay of 0.030 GBq or 2.35%, with no significant difference observed between glass and resin despite differences in preparation (P = .0697). Resin showed significantly higher activity lost to delivery system residual than glass (0.039 GBq vs 0.010 GBq, 3.01% vs 0.61%, P < .001). The percent activity lost to residual varied with activity prepared, with a maximum of 20.1% and 16.2% for the smallest activities of resin and glass, respectively.
Conclusions: Residual activity loss differs between glass and resin microspheres. For resin microspheres in particular, percent residual activity loss increases with lower prepared activities. Protocols for activity calculation and preparation, patient dosimetry, and regulatory compliance must take these losses into consideration prospectively.
