Case 10
A 45-year-old woman was referred for exercise 99mTc-sestamibi SPECT MPI because of an abnormal ECG. She denied cardiac symptoms.
She exercised for 5:16 minutes on a Bruce protocol (7 METs). Peak heart rate was 158 beats/min (90% of maximal age-predicted heart rate). No exercise-induced symptoms were reported, and the blood pressure and ECG responses were normal.
The short-axis SPECT images demonstrate a mild reversible defect in the anterior and anteroapical regions. The defect location and appearance are consistent with breast attenuation artifact, but the presence of defect reversibility is suggestive of ischemia.
