【摘要】：目的：探讨CT检查联合超声检查在诊断和鉴别诊断腮腺良恶性肿瘤中的应用价值,以提高术前诊断率,为临床制定治疗方案提供参考依据。资料与方法：回顾性分析我院2008年2月-2012年11月收住的117例病例资料完整的腮腺肿瘤患者术前CT和超声检查的影像学资料,CT上分析肿瘤位置、大小、形态、边界、密度、强化表现、是否侵犯周围组织结构以及有无淋巴结转移等情况；超声检查将二维超声和彩色多普勒显像(CDFI)相结合,观察病灶的位置、大小、形态、边界、内部回声、后方回声、血流分布及强度,根据CT成像或超声成像分别进行诊断,并综合CT及超声表现进行联合诊断,分别与病理诊断结果进行比较,作相关统计学分析。结果：CT对病变的定位符合率达到94.87%；CT成像对117例腮腺肿瘤的诊断符合率为77.78%,超声对117例腮腺肿瘤的诊断符合率为78.67%,两者之间的差异无统计学意义(P0.05)；CT与超声联合应用的诊断符合率达89.74%(105/117),与单独应用CT成像或超声相比,之间的差异均有统计学意义(P0.05)：两者联合应用于腮腺肿瘤诊断的准确性明显优于二者独立应用。结论：腮腺良、恶性肿瘤,在部位、形态、边界、侵袭性、淋巴结转移等征象上有显著差异,CT与超声检查对腮腺良、恶性肿瘤的诊断及鉴别诊断均有较高的应用价值,CT和超声联合应用于腮腺肿瘤的诊断,可提高术前影像学对腮腺良恶性肿瘤诊断的符合率。
[Abstract]:Objective: to explore the value of CT combined with ultrasound in the diagnosis and differential diagnosis of benign and malignant tumors of parotid gland in order to improve the preoperative diagnosis rate and provide reference for clinical treatment. Materials and methods: Ct and ultrasonographic data of 117 patients with parotid gland neoplasms admitted in our hospital from February 2008 to November 2012 were analyzed retrospectively. The location, size, shape, boundary and density of the tumors were analyzed on CT. Enhanced findings, invasion of surrounding tissue structure and lymph node metastasis, ultrasound examination combined two-dimensional ultrasound with color Doppler imaging (CDFI) to observe the location, size, shape, boundary, internal echo, rear echo, and so on. The distribution and intensity of blood flow were diagnosed according to CT imaging or ultrasound imaging, and combined with CT and ultrasound findings. The results were compared with pathological diagnosis, and the correlation statistical analysis was made. Results the diagnostic coincidence rate between CT and ultrasound was 77.78 for 117 parotid gland tumors and 78.67 for ultrasound in 117 parotid gland tumors. There was no significant difference between them. The diagnostic coincidence rate was 89.7475 / 117, compared with CT imaging or ultrasound alone. The difference between the two groups was statistically significant (P 0.05): the accuracy of the combined application in the diagnosis of parotid gland tumors was significantly better than that of the two independent applications. Conclusion: there are significant differences between benign parotid gland, malignant tumor, location, shape, boundary, invasion, lymph node metastasis and so on. The diagnosis and differential diagnosis of malignant tumors have higher application value. Ct and ultrasound can be used in the diagnosis of parotid gland tumors, which can improve the coincidence rate of preoperative imaging in the diagnosis of benign and malignant tumors of parotid gland.
