摘要
目的:探讨3.OT MR动态增强及DWI对腮腺肿瘤鉴别诊断的价值。方法:对我院2015年1月至2019年1月收治的30例腮腺肿瘤患者的MRI影像资料进行回顾性分析,并对良、恶性肿瘤的形态表现和肿瘤实质表观弥散系数进行比较。结果:良、恶性肿瘤的形态表现均具有统计差异,P<0.05;多形性腺瘤的表观弥散系数分别与腺淋巴瘤和恶性肿瘤作比较,均具有统计差异,P<0.05。但是,恶性肿瘤的表观弥散系数与腺淋巴瘤作比较,则不具有统计差异,P>0.05。结论:3.0T MR动态增强联合DWI有助于提升腮腺肿瘤的鉴别诊断价值,值得在临床上应用推广。
Objective To explore the value of 3.0 T MR dynamic enhancement and DWI in differential diagnosis of salivary gland tumors.Methods MRI images of 30 patients with parotid gland tumors admitted to our hospital from January 2015 to January 2019 were retrospectively analyzed,and the morphological manifestations of benign and malignant tumors and the apparent diffusion coefficient of tumor parenchyma were compared.Results The morphological manifestations of benign and malignant tumors were statistically different,P<0.05;The apparent diffusion coefficient of pleomorphic adenomas was statistically different from that of adenolymphomas and malignant tumors,P<0.05.However,there is no statistical difference in the apparent diffusion coefficient of malignant tumors compared with adenolymphomas,P>0.05.Conclusion 3.0 T MR dynamic enhancement combined with DWI can improve the differential diagnosis value of salivary gland tumors,and it is worthy of clinical application.
