【摘要】 目的探讨超声与磁共振检查联合应用对腮腺常见良恶性肿瘤的诊断价值。方法对47例腮腺肿瘤患者同时进行超声及MRI检查,根据超声和MRI成像分别进行诊断,并综合超声及MRI表现进行联合诊断,所有病例经手术病理证实。结果超声与MRI检查定性诊断腮腺肿瘤符合率分别为74. 47%(35/47)和78. 72%(37/47),二者间差异无统计学意义(P> 0. 05),两种方法联合使用的诊断符合率达89. 36%(42/47),灵敏度和特异度较单一检查方法均大幅度提高,漏诊率和误诊率大幅降低。结论超声和MRI检查对诊断腮腺肿瘤均有较高的临床价值,两者在诊断符合率上无明显差别,但两者联合应用诊断腮腺肿瘤的准确性明显优于两者单独应用,显著提高了术前对腮腺肿瘤定性诊断的符合率。更多还原

【Abstract】 Objective To evaluate the value of ultrasonography and magnetic resonance imaging in the diagnosis of benign and malignant parotid tumors. Methods 47 cases of parotid gland tumors in our hospital from April 2014 to August 2015 were treated by ultrasonography and MRI. According to ultrasonic imaging and MRI imaging diagnosed and combined with ultrasound and MRI manifestations of joint diagnosis,all cases were confirmed by surgery and pathology. Results The coincidence rate of ultrasonography and MRI in the diagnosis of parotid tumors was 74. 47%(35/47) and(37/47),respectively. There was no significant difference between the two groups(P > 0. 05). The diagnostic coincidence rate of the two methods was 89. 36%(42/47),and the sensitivity and specificity of the two methods were significantly increased compared with those of the single method. Conclusion The clinical value of ultrasonography and MRI in diagnosis of parotid tumors were high,both bad no significant difference in thediagnostic,but combined the both the accuracy of diagnosis of parotid tumos was better than either alone,which significantly improved the preoperative qualitative diagnosis coincidence rate of parotid gland tumor.更多还原
