Ultrafast assessment of left ventricular dyssynchrony from nuclear myocardial perfusion imaging on a new high-speed gamma camera

Purpose To validate the ultrafast assessment of left ventricular (LV) dyssynchrony by phase analysis using high-speed nuclear myocardial perfusion imaging (MPI) on a new gamma camera with cadmium-zinc-telluride (CZT) solid-state detector technology. Methods In 46 patients rest MPI with 960 MBq 99m T...

description Purpose To validate the ultrafast assessment of left ventricular (LV) dyssynchrony by phase analysis using high-speed nuclear myocardial perfusion imaging (MPI) on a new gamma camera with cadmium-zinc-telluride (CZT) solid-state detector technology. Methods In 46 patients rest MPI with 960 MBq 99m Tc-tetrofosmin was acquired on a dual-head detector SPECT camera (Ventri, GE Healthcare) and an ultrafast CZT camera (Discovery NM 530c, GE Healthcare) with acquisition times of 15 and 5 min, respectively. LV dyssynchrony was assessed using the Emory Cardiac Toolbox with established values for histogram bandwidth (male

Results In LV dyssynchrony the mean histogram bandwidths with the CZT camera ( n  = 8) and the Ventri camera ( n  = 9) were 123.3 ± 50.6° and 130.2 ± 43.2° ( p not significant) and 42.4 ± 13.6° vs. 43.2 ± 12.7° ( p not significant).

Intraclass correlation and the level of agreement between the CZT camera with a 5-min scan time and the Ventri camera were 0.94 ( p  < 0.001, SEE 14.4) and 96% for histogram bandwidth and 0.96 ( p  < 0.001, SEE 3.9) and 98% for SD.
