  Resting and stress images were obtained with 10.4, 32.5 mCi of tetrofosmin injected intravenously by standard protocol.  Myocardial perfusion scan demonstrates homogeneous and uniform distribution of the tracer uptake.  There is no evidence of reversible or fixed defect.  Gated SPECT revealed mild global hypokinesis, more pronounced in the septal wall possibly secondary to prior surgery.  Ejection fraction calculated at 41%.  End-diastolic volume of 115, end-systolic volume of 68.
