T1RHO MRI OF THE HUMAN BRAIN USING A SPIN-LOCKED SSFP PULSE SEQUENCE

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。在这项工作中，我们描述了一种新的脉冲序列（SL-TRUFI）基于平衡稳态自由进动或真fisp （TRUFI）脉冲序列。2名正常志愿者（平均年龄：25 - 4岁）在Siemens 3 Tesla Trio临床扫描仪上使用供应商提供的头部线圈进行磁共振成像。对于T1?，脉冲序列比单片法快。映射。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. In this work, we describe a new pulse sequence (SL-TRUFI) based on a balanced steady-state free precession or true-FISP (TRUFI) pulse sequence. MR imaging was performed on 2 normal volunteers (mean age: 25¿4) on a Siemens 3 Tesla Trio clinical scanner with the vendor-supplied head coil. The pulse sequence is faster than the single slice method for T1? mapping.
