摘　　要：目的探讨MR LAVA技术在腹部血管成像中的应用效果。方法方便选取该院2013年4月—2015年8月期间收治的120例腹部外科手术患者作为研究对象,根据临床检查方法的不同将其分为观察组64例和对照组56例,观察组患者采用MR LAVA技术,对照组患者采用多层螺旋CT检查。对比两组患者的各级血管显示率、动脉血管变异、静脉血管变异以及血管病变检出结果。结果观察组对于Ⅰ级、Ⅱ级和Ⅲ级血管的显示率分别为100%、100%和99.0%,对照组对于Ⅰ级、Ⅱ级和Ⅲ级血管的显示率分别为100%、100%和99.4%;观察组对于Ⅳ级、Ⅴ级血管的显示率分别为61.3%和59.8%,对照组对于Ⅳ级、Ⅴ级血管的显示率分别为67.9%和62.5%,两组患者的腹主动脉及其分支血管的显示率对比差异无统计学意义(P>0.05);在观察组患者出现动脉血管变异7例和静脉血管变异1例以及血管病变1例。对照组患者出现动脉血管变异6例和静脉血管变异1例以及血管病变1例。两组对比差异无统计学意义(P>0.05)。结论在腹部血管成像中,MR LAVA技术的应用效果十分显著,MR LAVA技术在腹部血管成像能达到多层螺旋CT血管成像的效果,而不用接受CT射线的损害,为腹部手术治疗提供了重要的参考依据,具有很高的临床应用价值。Objective To assess the value of Mr lava technique in abdominal vascular imaging effect. Methods Convenient selected from our hospital in April 2013 to August 2005, 120 cases of abdominal surgery patients as the research object, according to the different clinical examination methods will be divided into the observation group and control group, 64 case in the observation and 56 cases in the control group, the observation group were treated by Mr lava technology, control group patients by multi-slice spiral CT examination. Compared two groups of patients with blood vessels of all levels to display rate, arterial variation and venous vascular variation and vascular disease detection results. Results The observation group for grade I, grade II and grade III vascular display rates were 100%, 100% and 99.0%, control group for grade I,grade II and grade III vascular display rates were 100%, 100% and 99.4%; observation group in grade IV, V class vessels display rate was 61.3% and 59.8% respectively. The control group for grade IV, V class vessels display rate was 67.9% and62.5%, two groups of patients with abdominal aorta and branch display rate there was no obvious difference（P〈0.05）; in patients in the observation group had artery variations in 7 cases and venous vascular variation in 1 case and blood There were 6 cases in the control group, 1 cases of arterial vascular variation and 1 cases of venous vascular variation and 1 cases of vascular lesions. The difference between the two groups was not significant（P〈0.05）.Conclusion In abdominal vascular imaging, the application effect of Mr lava technology is very significant, Mr lava technique in abdominal vascular imaging can achieve the effect of multi-slice spiral CT angiography, rather than accept the damage of X-ray CT, treatment for abdominal surgery provides an important reference, has a high value in clinical application.
