目的 评价三维动态增强磁共振血管成像 ( 3DDCEMRA)在肾、肾上腺疾病术前诊断中的价值。方法 2 3例肾肿瘤患者 ,2 2例肾上腺肿瘤患者 ,2例肾动脉狭窄患者术前进行了 3DDCEMRA检查 ,将其结果同术中所见或DSA检查结果进行比较。结果 所有患者的 3DDCEMRA显示血管清晰 ,达到诊断要求 ,并且具有能同时显示血管外病灶的特点 ,其检查结果与手术所见和DSA检查结果基本相符。结论 3DDCEMRA是可靠的非创伤性诊断手段 ,有望逐步取代DSA检查
Objective To evaluate the value of three-dimensional dynamic contrast-enhanced magnetic resonance angiography (3DDCEMRA) in the preoperative diagnosis of renal and adrenal diseases. Methods Twenty-three patients with renal tumors, 22 patients with adrenal tumors, and two patients with renal artery stenosis were examined with 3DDCEMRA before operation, and the results were compared with those seen in intraoperative or DSA examination. Results 3DDCEMRA of all patients showed clear blood vessels, reached the diagnostic requirements and had the ability of displaying extravascular lesions at the same time. The results of the examinations were in good agreement with the findings of the surgery and DSA. Conclusion 3DDCEMRA is a reliable and non-invasive diagnostic tool that is expected to gradually replace DSA
