Comparison of99mTc-tetrofosmin uptakes on planar images with those in excised rats organs with those in excised rats organs

Abstract

Percent uptakes in PI measurement were greater than those in WC measurement. The difference between the two measurements was prominent in the early phases. The cardiac uptake in PI measurement was significantly greater than that in WC measurement at 10 min. It was considered that this discrepancy between the two measurements was caused by the Compton scatter from the organs adjacent to the heart.
