Overview

Single-photon emission CT (SPECT) can also be used to assess myocardial ischemia and viability, myocardial inflammation or infiltration. Scintigraphy with technetium (Tc)-labeled bisphosphonate has shown high sensitivity and specificity for imaging cardiac transthyretin amyloid.

Myocardial Viability Studies

Common imaging modalities to assess myocardial viability include:


Class IIb
"Non-invasive stress imaging (CMR, stress echocardiography, SPECT, PET) may be considered for the assessment of myocardial ischemia and viability in patients with CAD who are considered suitable for coronary revascularization. (Level of Evidence: B) "
". Exercise testing may be considered to detect reversible myocardial ischemia and investigate the cause of dyspnea(Level of Evidence: C) "
The above table adopted from 2021 ESC Guideline
