摘要
目的分析MRI诊断肾上腺嗜铬细胞瘤的特异性及敏感性。方法选择医院2017年11月-2018年11月收治的可疑肾上腺嗜铬细胞瘤患者98例,所有患者均进行超声和MRI诊断,对比超声与MRI诊断效能,并采用ROC曲线分析超声与MRI在评估肾上腺嗜铬细胞瘤中的价值。结果MRI检查肾上腺嗜铬细胞瘤的敏感度为97.78%,特异度为87.50%,准确度为96.94%,Kappa值为0.807;超声检查肾上腺嗜铬细胞瘤的敏感度为94.44%,特异度为75.00%,准确度为92.86%,Kappa值为0.593。MRI诊断与手术病理结果的一致性明显高于超声(P<0.05)。ROC曲线分析显示,MRI评估肾上腺嗜铬细胞瘤的敏感性高于超声(P<0.05)。结论MRI诊断肾上腺嗜铬细胞瘤的敏感度及特异度较高。
Objective To analyze the specificity and sensitivity of MRI in the diagnosis of adrenal pheochromocytoma.Methods 98 cases of patients suspected as adrenal pheochromocytoma in the hospital from November 2017 to November 2018 were selected.All patients were given ultrasound and MRI diagnosis,and the diagnostic efficacy of ultrasound and MRI was compared,and ROC curve was used to analyze the value of ultrasound and MRI in adrenal pheochromocytoma.Results The sensitivity,specificity, accuracy and Kappa value of MRI for adrenal pheochromocytoma were 97.78%,87.50%, 96.94% and 0.807.The sensitivity,specificity,accuracy and Kappa value of ultrasound for adrenal pheochromocytoma were 94.44%,75.00%,92.86% and 0.593.The consistency of MRI diagnosis with surgical pathological results was significantly higher than that of ultrasound (P<0.05).ROC curve analysis showed that the sensitivity of MRI for adrenal pheochromocytoma was higher than that of ultrasound (P<0.05).Conclusion MRI has high sensitivity and specificity in the diagnosis of adrenal pheochromocytoma.
