目的 评估动态增强磁共振血管 造影和螺旋CT血管造影在肾动脉狭窄中的 诊断价值。方法 对42例临床怀疑为肾动 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 84例动态增强 磁共振血管造影显示54例肾动脉血管均诊 断为肾动脉狭窄，而对42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，52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。

bjective To evaluate the dynamic enhanced magnetic resonance angiography and spiral CT angiography in the diagnosis value of renal artery stenosis. Methods 42 cases of patients with clinical suspicion of renal artery stenosis and dynamic enhanced magnetic resonance angiography scan and spiral CT angiography scan. Is the result of two methods will scan a double renal artery reconstruction after comparison, evaluation. Results 84 cases of dynamic enhanced magnetic resonance angiography showed 54 cases of renal arteries were diagnosed as renal artery stenosis, and 42 cases of patients with clinical suspicion of renal artery stenosis with spiral CT angiography scan, according to the results of 52 cases of blood vessels were diagnosed as renal artery stenosis. The two methods has good consistency. Conclusion Dynamic enhanced magnetic resonance angiography and spiral CT angiography can more accurate diagnosis of renal artery stenosis symptom, spiral CT angiography in sensitivity, specific values and accurate values are slightly higher than the dynamic enhanced magnetic resonance angiography, but dynamic enhanced magnetic resonance angiography way more secure.
