Figure 5. Effects of Arrythmias on Image Quality: (a) Arrythmias cause poor image quality: As the IR pulse is on, inconsistencies between the time of excitation and relaxation of the magnetization causes contrast variabilities, slice misregistration, blurring and or ghosting. For patients with extremely high heartbeats, triggering on alternating RR cycle (b) will help improve image quality) as compared to every RR cycle (a) [7]
