Abstract
From our measurements in a clinic setting of total counts in the heart during Tl-201 stress and rest imaging, we found the difference between the two imaging time points to be approximately 30%-40%, making the washout rate much slower than Tc-99m Teboroxime. The goal of this study was to investigate ways to accurately estimate the dynamic behavior of Tl-201 directly after exercise stress in an effort to predict the activity distribution at rest.
