目的评估螺旋CT与动态增强磁共振血管造影在肾动脉狭窄中的诊断价值。方法对84例临床疑为肾动脉狭窄的患者同时进行动态增强磁共振血管造影扫描和螺旋CT血管造影扫描。将两种方法扫描所得到的结果进行双肾动脉重建后进行比较,评价。结果 168例动态增强磁共振血管造影显示108例肾动脉血管均诊断为肾动脉狭窄,而对84例临床怀疑为肾动脉狭窄的患者进行螺旋CT血管造影扫描结果显示,104例血管均诊断为肾动脉狭窄。两种方法一致性较好。结论动态增强磁共振血管造影和螺旋CT血管造影都能比较准确的诊断肾动脉狭窄症状,螺旋CT血管造影技术在敏感度、特异肾动脉狭窄是由于多种病因引起的一种血管性疾病,临床上的表现为肾血管性高血压和缺血性肾病,值以及准确值都要略高于动态增强磁共振血管造影,但是动态增强磁共振血管造影方式更加安全。
Objective To evaluate the diagnostic value of spiral CT and dynamic contrast-enhanced magnetic resonance angiography in renal artery stenosis. Methods Eighty-four patients with clinically suspected renal artery stenosis were examined by dynamic contrast-enhanced MR angiography and spiral CT angiography. The results obtained by the two methods of scanning were compared and evaluated after renal artery reconstruction. Results 168 cases of dynamic contrast-enhanced magnetic resonance angiography showed that renal artery stenosis was diagnosed in 108 cases of renal artery, while in 84 cases of suspected renal artery stenosis, spiral CT angiography showed that 104 cases were diagnosed as renal Artery stenosis. Consistency between the two methods is better. Conclusions Both dynamic contrast-enhanced magnetic resonance angiography and spiral CT angiography can diagnose the symptoms of renal artery stenosis more accurately. The sensitivity and specificity of spiral CT angiography are the vascular diseases caused by various causes. Clinical On the performance of renal vascular hypertension and ischemic nephropathy, the value as well as the exact value should be slightly higher than dynamic contrast-enhanced magnetic resonance angiography, but dynamically enhanced magnetic resonance angiography more secure.
