目的:探讨高场磁共振仪肝脏三维容积快速扫描(LAVA)技术在诊断肾上腺嗜铬细胞瘤中的应用价值。方法:对9例拟诊为肾上腺嗜铬细胞瘤患者分别进行平扫和LAVA四期增强扫描,观察LAVA各期的影像学表现,分析病灶的影像特征。结果:经手术后病理证实8例为肾上腺嗜铬细胞瘤,1例为醛固酮腺瘤,诊断符合率为88.9%(8/9)。结论:LAVA技术能够清晰地显示肾上腺嗜铬细胞瘤的影像学特征及各期的血供变化,结合平扫,可大大提高肾上腺嗜铬细胞瘤术前诊断准确率。
Objective: To investigate the value of rapid magnetic resonance imaging (LVDA) of the liver in the diagnosis of adrenal pheochromocytoma. Methods: Nine patients who were diagnosed as adrenal pheochromocytoma underwent plain scan and LAVA four-phase contrast-enhanced scanning. The imaging features of LAVA were observed and the imaging features of the lesion were analyzed. Results: 8 cases of adrenal pheochromocytoma confirmed by pathology and 1 case of aldosterone adenoma, the diagnostic coincidence rate was 88.9% (8/9). Conclusion: The LAVA technique can clearly show the imaging characteristics of adrenal pheochromocytoma and the changes of blood supply in different stages. Combined with plain scan, the accuracy of preoperative diagnosis of adrenal pheochromocytoma can be greatly improved.
