    Pulse sequence extrapolation synthesizes new magnetic resonance (MR) images from existing data. This method accurately generates inversion-recovery (IR) images, enabling selective fat suppression and enhancement in MR imaging.

    Area of Science:

    • Medical Imaging
    • Magnetic Resonance Imaging (MRI)

    Background:

    • Previous magnetic resonance (MR) image synthesis methods relied on multiple spin-echo (MSE) data.
    • These methods generated spin-echo images for varied echo times and repetition times (TRs).

    Purpose of the Study:

    • To introduce and validate a novel "pulse sequence extrapolation" method for MR image synthesis.
    • To assess the feasibility of generating inversion-recovery (IR) images from MSE data.
    • To evaluate the accuracy and noise characteristics of synthesized IR images.

    Main Methods:

    • Acquired MSE data with a TR of 2,000 msec.
    • Applied the "pulse sequence extrapolation" technique to synthesize IR images with arbitrary inversion times (TIs).
    • Compared synthetic IR images visually and quantitatively against directly acquired IR images.

    Main Results:

    • Synthetic IR signals of brain parenchyma closely matched directly acquired signals (within 6% of full magnetization).
    • Noise levels in synthetic signals were approximately double those of direct acquisition signals, as predicted.
    • The method demonstrated capability for selective fat suppression and enhancement in IR imaging.

    Conclusions:

    • "Pulse sequence extrapolation" is a viable method for synthesizing IR images from MSE data.
    • This technique offers flexibility in generating IR images with desired parameters without new acquisitions.
    • The method holds potential for advanced applications like selective fat manipulation in MR imaging.
