Flow measurement by the development of phase differences during slice formation in MR imaging

Area of Science:

• Medical Imaging
• Biophysics

Background:

• Partial saturation sequences are known for high signal quality in Magnetic Resonance Imaging (MRI).
• Accurate measurement of physiological flow, such as blood flow, is crucial for various diagnostic applications.

Purpose of the Study:

• To develop and describe a novel method for measuring flow using partial saturation sequences.
• To assess the impact of flow encoding on image quality and signal retention.

Main Methods:

• The described method utilizes the shifting of the rephasing pulse following slice selection in a partial saturation sequence.
• Flow encoding was applied and compared to non-flow-encoded acquisitions.

Main Results:

• The technique successfully measures flow based on pulse shifting.
• Images acquired with and without flow encoding exhibited high similarity.
• The method retains the high signal characteristic of partial saturation sequences.

Conclusions:

• This novel method provides a viable approach for flow measurement within the framework of partial saturation MRI.
• The technique preserves image quality, making it potentially useful for clinical applications requiring flow quantification.
