摘要
通过对低场MRI各部位不同参数配置研究,提出较大视野、较薄层厚、小激励次数(NEX=1或2)的组合方案图像信噪比用空间分辩率适中,且扫描时间明显缩短,移动伪影较少,检查成功率可得到提高。
To optimize the configuration of the conventional SE and FSE sequence parameters in low field MRI. With the combination of larger vision, relatively thinner slice thickness, small number of excitation （ NEX = 1 or 2 ）, the signal-tonoise ration and the spatial resolution on follow-up images are moderate, the scan time is significantly shorter along with fewer motion artifacts, the check success rate is improved.
