摘　　要：目的探讨关于磁共振的快速自旋回波序列中的回波间隔对图像质量的影响。方法对20例正常体检者头部进行T2WI横轴位扫描,采用不同的回波间隔时间。对得到的图像进行比较分析。结果回波间隔时间长时,图像边缘模糊。结论临床应用时,需要综合考虑各个成像参数,选择合适的成像序列。Objective To study the effects of echo spacing in magnetic resonance fast spin echo series on image quality. Methods 20 cases of normal head were treated T2WI axial scanning. Different echo spacing time was used. The image carried on the comparative analysis. Results When echo intervaled time, the edge was blurred. Conclusion In clinical application, all of the imaging parameters need to be considered, selection of appropriate imaging sequence.
