ABSTRACT
Objective To observe the value of optimized temporal parallel acquisition technique (TPAT) sequence in evaluating cardiac structure and function in arrhythmia patients.Methods Totally 33 arrhythmia patients (arrhythmia group) and 48 normal rhythm subjects (normal group) underwent cardiac MRI with conventional cine (balanced steadystate free-precession [bSSFP]) sequence and optimized TPAT sequence.Myocardial thickness,cardiac function,myocardial strain parameters of left ventricle and image quality of 2 sequences were compared in the two groups,respectively.Results In arrhythmia group,there was statistical difference of myocardial thickness in 12 myocardial segments between the 2 sequences (all P < 0.05),as well as peak and average values of myocardial radial and circumferential strain (all P<0.05).In normal group,there was no statistical difference of myocardial thickness and stain parameters between the 2 sequences (all P>0.05).Additionally,no statistical difference of cardiac function was found between the 2 sequences in two groups (all P>0.05).In arrhythmia group,the image quality of optimized TPAT sequence was better than that of bSSFP sequence (P<0.05).Conclusion For arrhythmia patients,optimized TPAT cine sequence could improve image quality of cardiac MRI.
