A rapid gradient-echo acquisition (PSIF) was used to delineate the lumber spine. Because this sequence is heavily T2 weighted the cerebrospinal fluid shows a bright signal, the myelon has a poor signal. 5 healthy volunteers and 5 patients with suspected lumbar disc herniation were examined by this technique. All MR myelograms were compared with spin-echo sequences (sagittal and transversal slices). All lumbar disc herniations which were recognized by MRI were also delineated by MR myelography.
采用快速梯度回波采集（PSIF）来描绘腰椎。因为该序列具有重T2加权，脑脊液呈高信号，脊髓信号不佳。用该技术检查了5名健康志愿者和5名疑似腰椎间盘突出症患者。所有磁共振脊髓造影都与自旋回波序列（矢状位和横断位切片）进行了比较。所有经MRI识别的腰椎间盘突出症在磁共振脊髓造影中也能清晰显示。
