Intravenous insulin administration preparation for myocardial 18F-fluorodeoxyglucose viability imaging has the potential to reduce radiation exposure dose
Abstract:Purpose
This study aimed to identify and validate the optimal 18F-FDG activity and acquisition time for cardiac viability imaging with intravenous insulin administration based on a fixed 18F-FDG activity.
Methods
Cardiac positron emission tomography (PET) images from 30 patients with coronary artery disease (CAD) were retrospectively reconstructed into 900, 360, 180, 90, and 45 s durations. An optimal product of the maximum standardized uptake value (SUV) of the myocardium and segmental uptake (SU) and acqui… Show more
