摘要
目的:研究在肝门静脉成像检查中重复应用3.0 T MR NATIVE TrueFISP序列的可行性。方法:以2017年1月至3月期间滨州医学院附属医院招募的14名健康志愿者为研究对象。在相同的血流抑制翻转时间(BSP-TI)下,应用3.0TMRNATIVETrueFISP序列先后对这14名志愿者进行2次肝门静脉成像检查(两次检查的间隔时间为1～2周),然后对2次获取图像中肝门静脉及肝门静脉分支的显示情况进行主观评分,并计算其肝门静脉主干(MPV)、左支(LPV)、右支(RPV)图像的信噪比(SNR)和对比噪声比(CNR)。结果:这14名志愿者均成功地完成2次肝门静脉成像检查,均获得较为满意的图像。对这14名志愿者进行2次检查的结果显示,其图像中肝门静脉及肝门静脉分支显示情况的主观评分、肝门静脉MPV、LPV、RPV图像的SNR和CNR相比,P>0.05。结论:在肝门静脉成像检查中重复应用3.0 T MRI NATIVE TrueFISP序列的可行性良好。
objective: to study the feasibility of repeated application of 3.0t MR NATIVE TrueFISP sequence in hepatic portal vein imaging. Methods: 14 healthy volunteers recruited by binzhou medical college affiliated hospital from January to March 2017 were selected as the research objects. In inhibiting reverse blood flow to the same time(BSP-TI), the application of 3.0 T MR NATIVE TrueFISP sequence has 2 times to the 14 volunteers hepatic portal vein imaging(check twice time interval of 1 ~ 2 weeks), and then 2 times to get the image display profile of hepatic portal vein and hepatic vein branches subjective ratings, and calculate the hepatic portal vein trunk(MPV), left(LPV), right(RPV) image signal-to-noise ratio(SNR) and contrast to noise ratio(CNR). Results: all the 14 volunteers successfully completed two hepatic portal vein imaging examinations and obtained satisfactory images. The results of two examinations on the 14 volunteers showed that the subjective scores of the display of hepatic portal vein and hepatic portal vein branches in the images, SNR of hepatic portal vein MPV, LPV and RPV images and CNR were P > 0.05 compared with that of CNR. Conclusion: it is feasible to repeat 3.0t MRI NATIVE TrueFISP sequence in hepatic portal vein imaging.
