This article describes a basic 1.5-T hepatic magnetic resonance (MR) imaging protocol, strategies for optimizing pulse sequences while managing artifacts, the proper timing of postgadolinium 3-dimensional gradient echo sequences, and an effective order of performing pulse sequences with the goal of creating an efficient and high-quality hepatic MR imaging examination. The authors have implemented this general approach on General Electric, Philips, and Siemens clinical scanners.
本文介绍了一种基本的1.5-T肝脏磁共振（MR）成像方案、在处理伪影时优化脉冲序列的策略、钆增强三维梯度回波序列的正确时机，以及为实现高效、高质量肝脏MR成像检查而执行脉冲序列的有效顺序。作者已在通用电气、飞利浦和西门子临床扫描仪上实施了这种通用方法。
