Synopsis:

The balanced fast field echo (BFFE) technique employs a fully-balanced gradient waveform along all three axes, which allows magnetization to reach a steady state, providing fluids with good signal-to-noise ratios (SNRs) and excellent tissue contrast. Balanced fast field echo can then be used as diagnostic pulse sequence for blood vessels or fluid-filled tissues.

Magnetic resonance angiography (MRA) is a non-invasive vascular imaging technique. It can resolve the 3D morphology and structure of the circle of Willis when used in conjunction with three dimensional time-of-flight (3D TOF) and maximum intensity projection (MIP) technology. However, slow blood flow or saturation effects will cause signal loss in 3D TOF, and affect the accuracy of diagnosis.
