Does changing spatial and temporal resolutions in cine true FISP MR imaging affect left ventricular functional parameters in healthy volunteers?
Reduced spatial and temporal resolutions in cine true FISP MR imaging lead to decreased left ventricular functional parameters, highlighting the critical importance of temporal resolution in cardiac MRI.
The influence of changes in spatial and temporal resolutions on functional parameters in the left ventricle (LV) were investigated with magnetic resonance (MR) imaging with a modified true fast imaging with steady-state precession, or FISP, two-dimensional sequence that provided temporal resolution of 21-90 msec and spatial resolution of 1-3 mm. MR imaging in the heart was performed in 15 healthy volunteers. A decrease in LV functional parameters was observed with reduced spatial and temporal resolutions. The influence of temporal resolution was more relevant.
