This study addresses LV analysis at 3T in order to determine whether the administration of contrast agent has a significant effect on cardiac parameters. Pre and post contrast images of 12 healthy volunteers (no previous cardiac illness and Framingham score < 20%) were analysed. A paired t-test was performed on differences between mean pre and post contrast values of ejection fraction, end diastolic volume, end systolic volume, stroke volume, cardiac output and mass. Statistically significant differences were found for EDV, SV and mass which may impact on patient care. Findings also suggest normal ranges need to be established at 3T.
