Review Question Answers


    1)  Which of the following are dark blood imaging techniques?

    1. Spin echo
    2. Gradient echo
    3. Steady state free precession
    4. Fast gradient echo
    5. TruFISP

    Answer: A. Spin echo is the only dark blood imaging technique. Steady State Free Precession, TruFISP, and Fast Gradient Echo are all bright blood techniques.


    2)  Which of the following techniques is used to null myocardium for delayed enhancement imaging?

    1. Gradient echo
    2. Steady state free precession
    3. Inversion recovery
    4. Spin echo
    5. Velocity encoded imaging

    Answer: C. Inversion recovery pulses are used to null signal from normal myocardium to make areas with delayed enhancement more visible.


    3)  Which of the following is useful for volumetric measurements of ventricular size and mass?

    1. Spin echo
    2. Gradient echo
    3. Steady state free precession
    4. Inversion recovery
    5. Velocity encoded imaging

    Answer: C. Steady state free precession images show a clear border between the myocardium and the blood pool that is essential for performing volumetric measurements.
