Measured and estimated time activity curves derived from one of the patients infused with the radiotracer 99mTc-tetrofosmin (99mTc, 140 keV) in one of our dynamic cardiac SPECT studies. The activity of the left ventricle (LV), right ventricle (RV), myocardium (MY), liver (LIV) and lung (LN) were measured directly from the patient’s data. Other activity for stomach (STM), kidney (KID) and background (BG) tissue (total of 16 organs in the MCAT phantom) were estimated using a 1-tissue compartment model by providing generic wash-in and wash-out kinetic parameters.
