摘要
目的探讨盆腔无对比剂磁共振血管造影技术(Non-Contrast Enhanced Magnetic Resonance Angiography,NCEMRA)在髂静脉压迫综合征(Iliac Vein Compression Syndrome,IVCS)诊断及腔内介入指导的应用价值。方法进行了NCE-MRA[包括无对比剂和心电、呼吸门控触发的血管造影技术(Relaxation-Enhanced MR Angiography Without Contrast and Triggering,REACT)、平衡快速场回波技术(Balance Turbo Field Echo Magnetic Resonance Venogram,B-TFE MRV)、时间飞跃法技术(Time of Flight Magnetic Resonance Venogram,TOF-MRV)]及DSA检查且髂静脉受压部位和数量完全一致的38例下肢静脉疾病患者被纳入此研究,进行狭窄率的相关性分析。结果采用REACT、B-TFE MRV、TOF-MRV得到的狭窄率数据分别与DSA相比均无明显差异(t=-0.421、1.365、-0.941,P>0.05),但REACT的狭窄率与DSA相比差异最小(Cohen’s d值=0.060);REACT、B-TFE MRV及TOF-MRV两两之间的狭窄率相比,REACT的狭窄率与B-TFE MRV、TOF-MRV相比均无明显差异(t=-1.375、0.284,P>0.05),但REACT的狭窄率与TOF-MRV相比差异更小(Cohen’sd值=0.040),B-TFE的狭窄率与TOF-MRV相比差异较大(t=2.211,P=0.032)。结论NCE-MRA有助于提高IVCS的诊断率,进而能够进一步指导髂静脉腔内介入治疗。
Objective To evaluate the value of non-contrast enhanced magnetic resonance angiography(NCE-MRA)in the diagnosis and endovascular interventional guidance of iliac vein compression syndrome(IVCS).Methods A total of 38 patients with lower limb venous diseases examined by NCE-MRA,including relaxation-enhanced MR angiography without contrast and cardiogram(REACT),balance turbo field echo magnetic resonance venogram(B-TFE MRV)and time of flight magnetic resonance venogram(TOF-MRV)and DSA with the same number and location of iliac vein compression were included.The correlation of stenosis rate was analyzed.Results The stenosis rates of REACT,B-TFE MRV and TOF-MRV had no significant difference compared with DSA,respectively(t=-0.421,1.365,-0.941,P>0.05),but the stenosis rates of REACT had the least difference compared with DSA(Cohen’s d=0.060).The comparison of the stenosis rate between either two of REACT,B-TFE MRV and TOF-MRV showed that the stenosis rate of REACT compared with B-TFE MRV,TOF-MRV had no obvious difference(t=-1.375,0.284,P>0.05).However,compared with TOF-MRV,the stenosis rate of REACT was smaller(Cohen’s d=0.040),and the stenosis rates of B-TFE MRV was larger(t=2.211,P=0.032).Conclusion NCE-MRA can improve the diagnostic rate of IVCS,which can further guide the intraventral treatment of iliac vein.
