Positron Emission Tomography Assessment of Myocardial Viability

Nishant R. Shah, MD, MPH, MSc; Sharmila Dorbala, MD, MPH; Vasken Dilsizian, MD

OVERVIEW
Differentiation of left ventricular (LV) dysfunction due to myocardial hibernation or stunning versus myocardial scar is critical for appropriate treatment and prognosis assessment. 18F- luorodeoxyglucose (FDG) PET imaging is the only FDA approved technique for the assessment of myocardial viability. Accurate detection of viable myocardium by PET is achieved by referencing regional 18F-FDG metabolism to regional resting myocardial blood flow on perfusion images. The purpose of this document is to highlight the key elements of appropriately performed, high-quality myocardial positron emission tomography (PET) to detect viable myocardium. Topics covered include: indications, contraindications, optimal testing protocols, and reporting templates.

Positron Emission Tomography Assessment of Cardiovascular Inflammation

Nishant R. Shah, MD, MPH, MSc; Sharmila Dorbala, MD, MPH; Vasken Dilsizian, MD

OVERVIEW
18F-FDG myocardial PET is becoming an accepted tool for diagnosing active cardiovascular inflammation. Increased glucose metabolism is a hallmark of activation of cells involved in both innate and adaptive immunity. The purpose of this document is to highlight the key elements of appropriately performed, high quality myocardial positron emission tomography (PET) to detect active cardiovascular inflammation. Topics covered include: indications, contraindications, optimal testing protocols, and reporting templates.
