Assesment of left ventricular synchrony with SPECT myocardial perfusion imaging: technical and methodological secrets to obtain left ventricular synchrony data

Abstract

Imaging methods to assess left ventricular synchrony were developed with the aim of assessing dysynchrony in order to resynchronize patients with heart failure, improve functional capacity and prognosis. Nuclear medicine developed phase analysis, an automated, reproducible technique that presents low inter- and intra-observer variability and allows to locate in a three-dimensional way where the left ventricular contraction begins and ends.

The objective of this subject review is to learn the principles of the acquisition, processing and basic concepts of how of the phase analysis software works for a correct interpretation of the left ventricular synchrony images.
