The scan technique and reconstruction method presented in this work are designed to reduce the scan duration of 2D time-of-flight angiography sequences. The acquisition makes use of a sliding-slice technique that eliminates the need for steady-state prep pulses, which are needed before each slice in time-of-flight. This reduces the total scan time of a 2D spiral time-of-flight sequence by almost half, without a reduction in k-space coverage.
