真实稳态自由进动序列结合时间空间标记反转脉冲技术在肝脏无对比剂磁共振血管造影中的应用

Non-contrast-enhanced Magnetic Resonance Angiography for Selective Visualization of Hepatic Vasculature with True Steady-state Free-precession Sequence Combined with Time-spatial Labeling Inversion Pulses

    摘要
  • 摘要:
      目的  探讨真实稳态自由进动序列(true steady-state free-precession, true SSFP)结合时间空间标记反转脉冲(time spatial labeling inversion pulse, T-SLIP)技术在肝动脉、门脉及静脉系统选择性成像中的应用, 以提高对肝脏无对比剂磁共振血管造影(non-contrast-enhanced magnetic resonance angiography, NCE-MRA)的认识。
      方法  简述本院无对比剂磁共振肝脏血管造影扫描方案, 回顾性分析2010年10月至2011年5月4例临床病例。
      结果  4例患者均成功扫描, 肝动脉均未发现变异, 门脉系统受侵犯2例, 门脉系统增宽1例; 肝静脉受累1例, 伴副肝静脉开放。
      结论  true SSFP序列结合T-SLIP技术能够有效应用于选择性肝脏无对比剂MR血管造影, 具有广阔的临床应用价值。

     

    Abstract:
      Objective  To explore the value of the respiratory-triggered three-dimensional (3D) true steady-state free-precession (SSFP) combined with time spatial labeling inversion pulse (T-SLIP) in the selective visualization of hepatic arteries, portal veins and hepatic veins, with an attempt to improve the understanding of non-contrast-enhanced magnetic resonance angiography (NCE-MRA) for liver.
      Methods  The clinical data of four patients who underwent NCE-MRA in our hospital from October 2010 to May 2011 were retrospectively analyzed.
      Results  Selective visualization of hepatic vessels was successfully acquired in all cases. No anatomical variation of hepatic arteries was found. Two cases had portal vein invasion and one case had broadening of main portal vein. One case had hepatic veins involvement, accompanied with the opening of accessory hepatic vein.
      Conclusion  3D true SSFP scan with T-SLIP can be effectively applied for the selective NCEMRA of hepatic vasculature.
