Figure 3 Adenosine Stress Tl/Tc Protocol: Normal Myocardial Perfusion
Adenosine stress Tl-201/rest Tc-99m tetrofosmin high-speed SPECT myocardial perfusion imaging of a 60-year-old man with a history of hypertension, diabetes, and liver failure being evaluated for liver transplantation. Invasive coronary angiography subsequently revealed normal coronary arteries. Note the absence of significant extracardiac activity on the rest Tc-99m tetrofosmin (Tetro) images despite initiation of imaging 2 min after rest injection. Abbreviations as in Figure 1.
