FIGURE 5. (A) Simulated changes in ^99mTc-GSA liver–activity curve if hepatic blood flow is reduced by 20% (solid line) or 50% (dashed line). (B) Simulated changes in ^99mTc-GSA liver–activity curve if receptor concentration is reduced by 20% (solid line) or 50% (dashed line). ^99mTc-GSA liver time–activity data from sham-operated rat are indicated by circles. kcts = kilocounts.
