Following SE T 1WI and turbo SE T 2WI of transversal section, enhanced dynamic scans with gradient echo sequence and central K space acquisition without breath holding were performed at seven contiguous sections and eight phases.

• 轴位常规自旋回波T1加权成像及快速自旋回波T2加权成像后，采用平静呼吸状态下梯度回波K空间中心部分采集技术、7个连续层面8个时相动态增强扫描。
