MSCT在腮腺良恶性肿瘤诊断中的应用价值

摘要

目的：探讨多层螺旋CT（MSCT）在腮腺良恶性肿瘤诊断及鉴别诊断中的应用价值。方法回顾性分析160例经临床确诊的腮腺肿瘤患者的MSCT影像资料，统计腮腺肿瘤的供血动脉数目及动脉主干的平均直径，评估肿瘤内的供血血管生成情况，与临床病理结果比较，评价MSCT对腮腺良恶性肿瘤的诊断及鉴别诊断价值。结果 CT平扫时，腮腺良恶性肿瘤的边缘、形态等差异显著（P<0.05）；增强CT扫描时，腮腺良恶性肿瘤的强化方式、一期强化幅度、淋巴结转移情况等差异显著（P<0.05)；肿瘤直径、延时强化方式差异不显著（P>0.05）。MSCT可区分良恶性肿瘤的瘤体供血情况，如供血血管主干的数目及直径、血管包埋或破坏的情况等。结论MSCT是腮腺良恶性肿瘤诊断及鉴别诊断的重要影像工具，可以准确判断肿瘤的供血、周围侵犯及淋巴结转移等情况，可作为腮腺肿瘤患者术前诊断的首选工具。%Objective To explore the effectiveness of application of MSCT (Multi-Slice Spiral Computerized Tomography) in diagnosis of benign and malignant parotid tumors. Methods The CT imaging data of 160 cases of parotid tumors were retrospectively analyzed. The number of the blood supply arteries in parotid tumors and the average diameter of the main arteries were calculated and the angiogenesis in tumor was assessed, which were compared with the clinical pathology results so as to make an assessment of the effectiveness of application of MSCT in diagnosis and differential diagnosis of benign and malignant parotid tumors. Results There were statistically significant differences in the edge and tumor morphology of benign and malignant parotid tumors in CT scan (P<0.05);in the enhanced CT scan, signiifcant differences were seen in the enhancement mode, the Phrase I strengthening amplitude and lymph node metastasis of benign and malignant parotid tumors (P<0.05);the tumor size and delay enhancement mode had no statistical signiifcance (P>0.05). MSCT could display the tumor the condition tumor blood supply, such as the diameter and number of trunk blood vessels, vascular entrapment or damage. Conclusion MSCT was an important imaging tool in the diagnosis and differential diagnosis of benign and malignant parotid tumor, which could be used as the ifrst choice for the diagnosis of the tumors.
