三维动态增强MRA在肾肿瘤术前诊断中的意义

3D DCE MRA in the Diagnosis of Renal Neoplasm

摘要: 目的　评价三维动态增强磁共振血管成像 (3DDCEMRA)在肾肿瘤术前诊断中的价值。方法2 3例肾肿瘤患者术前进行了 3DDCEMRA检查, 将其结果同手术所见和DSA检查结果进行比较。结果　 2 3例患者的 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。结论　 3DDCEMRA是可靠的非创伤性诊断手段, 有望逐步取代DSA检查。

Abstract: Objective To evaluate the usefulness of 3D DCE MRA in the diagnosis of renal neoplasm. Methods 3D DCE MRA was performed on 23 patients with renal neoplasm. Comparison with surgical findings and DSA was made. Results 3D DCE MRA clearly showed vascular anatomy. It had advantages regarding demonstration of extravascular lesions. Conclusion 3D DCE MRA is a reliable noninvasive imaging diagnostic method.
