标题： Quantitative T2 Estimation Using Radial Turbo Spin Echo Imaging

摘要： 在基于腹部成像的T2定量表征方面，人们对其兴趣有所增加。 基于自旋回波或快速自旋回波序列的技术耗时较长，因为它们需要多次采集以获得足够数量的TE图像，从而准确进行T2映射。 基于径向快速自旋回波（RADTSE）的方法已被证明可以使用高度欠采样的数据从一次采集中生成准确的T2图。 在本研究中，我们介绍了RADTSE技术的细节，总结了与脉冲序列设计和重建算法相关的进展。 还展示了来自幻影和体内成像实验的结果。 显示英文摘要

摘要： There has been increased interest in the quantitative characterization of tissues based on T2 in abdominal imaging. Techniques based on spin-echo or turbo spin-echo sequences are time consuming because they require multiple acquisitions for obtaining an adequate number of TE images for accurate T2 mapping. Radial turbo spin echo (RADTSE) based methods have been shown to generate accurate T2 maps from a single acquisition using highly undersampled data. In this work, we present details of the RADTSE technique, summarizing developments related to the design of pulse sequence and reconstruction algorithms. Results from phantom and in vivo imaging experiments are also presented.
