SPECT using new detectors allows the quantification of myocardial blood flow and is now also suited to patients with a high BMI. Clinical consensus recommendations on the appropriateness of each technique were derived following a European quantitative cardiac imaging meeting and using a real-time Delphi process. Technical improvements to the quantification of pathophysiological parameters of myocardial ischaemia can be achieved.

CT perfusion imaging is not frequently used but CT offers coronary angiography data, and invasive catheter-based methods can measure coronary flow and pressure. MRI does not involve exposure to ionizing radiation, similar to echocardiography, which can be performed at the bedside. SPECT is most commonly used for clinical myocardial perfusion imaging, whereas PET is the clinical reference standard for the quantification of myocardial perfusion.
