Why the study?

Do TrueFISP sequence protocols with shared phases alter the assessment of left ventricular volumes and ejection fraction compared to a standard segmented protocol in healthy volunteers?

Population

10 healthy male volunteers

Comparison

TrueFISP sequence protocols with shared phases vs Protocol A: internal standard of reference…

Implication

Phase sharing in SSFP cine MRI may underestimate LV volumes and EF; leaves open sequence-specific reference values for serial research and clinical assessments.

Do TrueFISP sequence protocols with shared phases alter the assessment of left ventricular volumes and ejection fraction compared to a standard segmented protocol in healthy volunteers?

Population

10 healthy male volunteers

Intervention

TrueFISP sequence protocols with shared phases (Protocol B: segmented, shared phases, tRes 34.1 msec, TA 10 beats per slice; Protocol C: real-time, shared phases, parallel acquisition technique, tRes 47.3 msec, TA 24 beats for 12 slices)

Comparator

Protocol A: internal standard of reference, segmented TrueFISP sequence without shared phases (tRes 34.5 msec, TA 18 beats per slice)

Outcome

End-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), and ejection fraction (EF)surrogate

The use of view sharing techniques in SSFP cine MR imaging systematically underestimates end-diastolic volume, stroke volume, and ejection fraction, which must be accounted for during follow-up examinations.
