分段回波平面采集已合并到多回波成像序列中，以产生用于快速横向弛豫测量的 MRI 方法。该方法在凝胶体模和大鼠大脑上进行了演示，发现可以产生 T-2 的无偏估计。梯度性能可能是该技术实施的限制因素，并且由于需要更高的带宽而导致信噪比的成本增加，这对于平面回波采集来说是典型的。 (C) 2000 年学术出版社。
Segmented echo-planar acquisitions have been incorporated into a multiecho imaging sequence to produce a MRI method for rapid transverse relaxometry. The method is demonstrated on gel phantoms and rat brain and found to produce unbiased estimates of T-2. Gradient performance can be a limiting factor for the implementation of this technique and there is a cost in signal-to-noise ratio resulting from the higher bandwidth required, as is typical for echo-planar acquisitions.
