WebThe aliasing pattern resulting from a wave-encoding is not only spread in the phase and partition encoding directions but also in the frequency encoding direction. As a result, coil sensitivity variations along three directions can be exploited more efficiently, leading to a further improvement in PI reconstruction conditions and, therefore, a better image quality. WebBecause these nuclear magnetic properties of water protons are sensitive to the chemical, biological, and physiological environments of tissues, water molecules can be considered as endogenous probe molecules for in vivo “label-free” MRI to report the normal and abnormal tissues based on disease-induced changes in chemical, biological, and …

Gradient echo sequences present shorter echo times since only one RF pulse is required for each sequence. Modern fast-switching gradient coils also require increasing the slew rate, allowing for faster changes in gradient echo sequences and decreasing the repetition time.
