| 目的 通过对六种扫描序列的分析与评价以期达到发现中低场强中最有价值的扫描序列及序列组合的目的 。方法 对26名临床怀疑肝脏病变的患者进行了MR检查,均应用了快速自旋回波(TSE)的T2加权像,快速梯度回波(TFE)的反相位T1加权像,快速自旋回波加脂肪抑制的T2加权像,标准自旋回波(SE)的T1和T2加权像,快速梯度回波(TFE)的动态增强扫描等六种扫描序列,对各序列的图像质量及腹部常见正常结构的显示进行了分析和评价。结果 快速自旋回波(TSE)T |

| Purpose To evaluate the value of six sequences of magnetic resonance imaging in liver and upper abdomen. Methods Twenty-six patients suspected focal liver disease underwent T1 and T2-weighted conventional SE, T2–weighted with and without fat-suppressed Turbo-SE, opposed phase fast field echo(FFE) and dynamic enhanced(T1-TFE) MR imaging at 0.5T. The image quality was analyzed with six sequences above mentioned. Results Quality analysis demonstrated that TSE imaging without fat suppressed had highest images quality; conventional T2-weighted SE imaging, the lowest. TSE imaging without fat-suppressed was preferred 92%(24/26 cases) of the time and conventional T1-weighted SE imaging 23.07%(6/26) of the time as regards overall imaging quality. There was statistically significant difference (P<0.005) between TSE without fat-suppressed and other five imaging sequences in image quality. Conclusion It is more important for us how to use reasonably the sequences in liver and upper abdomen than obtained high image quality. |
