Abstract
In this study, (123)I-FP-CIT biodistribution and dosimetry was determined in 10 adult male patients using planar gamma camera imaging alone or in combination with single photon emission computed tomography /X-ray computed tomography (SPECT/CT) imaging. Dosimetric assessment using planar plus SPECT/CT imaging resulted in significantly different estimates of organ-absorbed doses compared to estimates based on planar imaging alone. We conclude that the use of complementary SPECT/CT measurements in biodistribution studies is valuable for determining the organ doses more accurately.
