我们开发了一种快速的方法来获得弛豫映射的磁共振成像（MRI）的基础上两个反转恢复采集和参考采集，同时保持高灵敏度，利用全动态范围的MRI信号。最佳反演时间估计在人脑中使用标准误差传播theory.In vivomeaschromatography预测9名健康志愿者产生的值在灰质和白色的问题，在合理的协议与文献值使用传统的方法。所提出的方法应该是有用的临床研究，因为地图可以在几秒钟内获得。
We developed a fast method to obtain relaxation maps in magnetic resonance imaging (MRI) based on two inversion recovery acquisitions and a reference acquisition, while maintaining high sensitivity by utilizing the full dynamic range of the MRI signal. Optimal inversion times for estimating in the human brain were predicted using standard error propagation theory.In vivomeasurements on nine healthy volunteers yielded values of in gray matter and in white matter, in reasonable agreement with literature values using conventional approaches. The proposed method should be useful for clinical studies because the maps can be obtained within a few seconds.
