    Summary

    Electrocardiogram (ECG) is unreliable for sheep cardiac MRI. Researchers developed a software method using left ventricular pressure (LVP) for accurate gating, improving ovine cardiac imaging efficiency and reliability.

    Area of Science:

    • Cardiovascular imaging
    • Magnetic Resonance Imaging (MRI)
    • Ovine models

    Background:

    • Cardiac MRI requires gating signals for motion compensation.
    • Electrocardiogram (ECG) is the standard human cardiac MRI gating signal.
    • ECG is unreliable for gating in sheep cardiac imaging.

    Purpose of the Study:

    • To develop a reliable gating signal for ovine cardiac MRI.
    • To improve the accuracy and efficiency of cardiac imaging in sheep.
    • To investigate the use of left ventricular pressure (LVP) as a gating signal.

    Main Methods:

    • Developed a software-based method utilizing left ventricular pressure (LVP) for gating.
    • Calculated the time derivative of LVP (dP/dt) to identify key cardiac phases.
    • Employed MR tissue tagging to compute 3D strain during diastole.

    Main Results:

    • LVP provided a clean and reliable gating signal in sheep, unlike ECG.
    • The LVP-based method enabled accurate, non-delay triggering for both systolic and diastolic phases.
    • Combined LVP gating with MR tissue tagging for comprehensive 3D strain analysis.

    Conclusions:

    • Left ventricular pressure (LVP) is a superior gating signal for ovine cardiac MRI compared to ECG.
    • The developed software and digital circuit offer a reliable, time-efficient method for ovine cardiac imaging.
    • This approach enhances the quality and diagnostic potential of cardiac MRI in sheep models.
