  • Single Photon Emission Computed Tomography (SPECT) perfusion imaging relies on established measurement techniques.

Purpose of the Study:

  • To explore the current state and future potential of quantitative imaging in myocardial perfusion assessment.
  • To highlight the clinical utility of quantitative SPECT in evaluating cardiac function and risk.

Main Methods:

  • Standardized measurements for SPECT perfusion imaging.
  • Electrocardiography (ECG) gating for assessing regional and global ventricular function.
  • Computer-aided image classification against a normal database.
