Abstract

A method for producing calculated T1 images with high signal-to-noise ratio and good spatial resolution using surface coils is presented. Separate transmit and receive rf coils with electronic decoupling are employed to insure uniform B1 excitation. The sensitivity profile of the receiver coil is normalized out of the image by the T1 calculation. T1 values determined by this method show close agreement with previously reported values.

摘要

提出了一种使用表面线圈来生成具有高信噪比和良好空间分辨率的计算T1图像的方法。采用具有电子去耦的单独发射和接收射频线圈，以确保均匀的B1激发。通过T1计算将接收线圈的灵敏度分布从图像中归一化去除。用该方法确定的T1值与先前报道的值显示出密切的一致性。
