Abstract
Background While SSFP CMR is the gold standard for assessing left ventricular (LV) function, it requires a regular cardiac rhythm and frequent breath-holds and not all patients with cardiovascular disease are able to achieve this. It is known that Compressed Sensing (CS) greatly reduces data acquisition time however its accuracy for LV volume and mass is currently unknown. This study compares ventricular function measurements by CS to those obtained from standard SSFP cines.
Highlights
While SSFP CMR is the gold standard for assessing left ventricular (LV) function, it requires a regular cardiac rhythm and frequent breath-holds and not all patients with cardiovascular disease are able to achieve this
fully sampled SSFP (FULL) images were acquired over 14 heart-beats with TE = 1.54 ms, a = 51°, 25 frames, matrix 256×256 and iPAT factor 2
R9.2 images were acquired over 2 beats with TE = 1.27 ms, a = 42°, 19frames, matrix 192×129
