Comparative Study
Comparison of a multi-breath-hold and a single breath-hold cine imaging approach for 4D guide-point modeling of the left ventricle.
Guide-point modeling (GPM) enables reliable and time-efficient assessment of left ventricular (LV) volumes when using sequences that allow acquisition of short- and long-axis scans within a single breath-hold. Slice misalignment may influence GPM analysis of standard multi-breath-hold images due to image acquisition in different breath-holds. Thus, our study aimed to assess if such an approach allows for reliable volumetric calculations in the clinical routine. ⋯ Cine short- and long-axis images that had been acquired in different breath-holds can be reliably evaluated by the GPM approach.
