| 摘 要： | 目的通过应用高压注射器在肝脏磁共振中的动态扫描，探讨磁共振高压注射器在动态增强中的临床应用价值，并对其优越性和应用程序进行了分析与讨论。方法对100例可疑肝脏疾病患者先行常规扫描，然后使用高压注射器注射（机型：Spectris MR Injector system），对选定的病变区域采用横断面SPGR序列行3D动态扫描和延迟扫描。注射速度：3．0ml／s；注射剂量：0．2mmol／kg；注射时间：动脉期20～25s，静脉期65～70s，平衡期90～120s；注射部位：肘静脉；注射方式：团注法。结果所有病例的检查均一次成功，图像符合研究组质量标准，达到诊断效果。结论应用高压注射器行肝脏MRI动态扫描，能确保肝脏动态扫描各种参数指标的相对恒定，通过精确的调节造影剂的注射速度、注射剂量、配合肝脏成像程序，能提高影像质量，增加病变诊断率。

| Abstract: | Objective To evaluate the clinical value of high pressure injector in application of dynamic contrast-enhanced MRI in liver. Methods 100 patients with known or suspected focal liver lesion were studied by dynamic contrast-enhanced MRI with high pressure injector. Results All the cases were examined successfully and achieved good diagnostic effectiveness. Conclusion Dynamic contrast-enhanced MRI with high pressure injector was able to provide the pattern and degree of enhancement of hepatic lesions which was helpful for increasing the diagnostic rate of diseases in liver. |
