摘　　要：目的探讨腮腺病变的MRI诊断与鉴别诊断。方法回顾性分析30例腮腺区病变,所有病例均行MRI平扫及增强扫描,并由手术或病理证实,将MRI表现与病理结果对照研究。结果30例病变中,良性病变26例,以多形性腺瘤居多(13/26),T1WI为低信号,T2WI为高信号,信号均匀或不均匀,增强后明显强化,其次为腺淋巴瘤(7/26),病变边缘光整,T1WI为低信号,T2WI为高信号,易囊变或液化,大多数为轻中度强化,恶性病变4例,多数为粘液表皮样癌,表现为边界不清楚,浸润性生长,部分病变可有增大淋巴结。结论根据MRI表现,结合临床,多数腮腺病变可做出正确诊断。Objective To evaluate the MR/diagnosis and different diagnosis of parotid disease. Methods 30 patients proved with parotid disease were analyzed retrospectively. All patients were scanned with plain and contrast MRI. Results 30 benign tumers were 13 pleomorphism tumors, 7 Warthin tumors, 2 hemangiomas,2 mucus skin carcinoma, 1 drive pipe cancer 1 papillate pouch gland cancer;2 chronic mumps; 1 tuberculoma;l mikulics. All lesions were found clearly, Benign lesions demonstrated regular and clear margin.Malignant lesions demonstrated irregular and unclear margin.24 lesions showed low signal intensity on T1WI and high intensity on T2WI; Angioma had its symbolical signals and it was iso-intensity or high intensity on T1WI; High intensity on T2WI. Conclusion According to the image findings ,combined with clinical manifestation,most parotid disease can be diagnosed correctly.
