Impression:
  • No fixed or reversible perfusion abnormalities detected.

    Note:
    Reduced uptake in the anterior wall is most likely to be breast attenuation.
    Typically, breast attenuation is visible in the apical half of the anterior wall in the sagittal long axis and around 12 O'clock in the coronal slices.
    In this patient, attenuation is most pronounced in the rest study (arrows).

    An alternative explanation would be myocardial injury and reverse changes. However, the above finding is so common that the latter explanation is much less likely. Furthemore, there is no history or ECG changes indicating prior MI.
