CT轴位平扫与冠状位平扫对鼻窦肿瘤的诊断及鉴别价值研究

目的探析CT轴位平扫与冠状位平扫在鼻窦肿瘤患者临床诊断与鉴别诊断中的应用价值。方法选择我院耳鼻喉科2013年8月-2015年8月期间收治97例行CT检查的患者作为研究对象,所有患者均行CT检查,包括轴位平扫与冠状位平扫,以病理结果为基准,计算不同扫描方法的诊断准确率并与联合扫描的结果进行比较,同时总结良恶性鼻窦肿瘤的影像学特征与鉴别要点。结果 97例患者病理结果为56例良性肿瘤、41例恶性。CT轴位平扫诊断准确率为70.1%(68/97),CT冠状位平扫诊断准确率为77.3%(75/97),二者差异的比较无统计学意义。轴位+冠状位平扫诊断准确率为88.7%(86/97),分别高于CT轴位平扫与冠状位平扫,差异有统计学意义(P0.05),提示轴位+冠状位联合具有更大诊断价值。结论 CT为非侵入性且分辨力较高的检查手段,可直接显示鼻腔、鼻窦内病灶大小与范围、肿瘤性病变、沟通途径及病变周围情况,有利于尽早确诊并为临床治疗方案制订提供有用信息。轴位平扫可作为冠状位平扫的补充,获得窦壁骨质破坏及周围组织浸润情况等信息,进一步提高诊断准确性。

Study on the Value of CT Axial Scan and Coronal Scan in the Diagnosis and Differentiation of Nasal Sinus Neoplasms

Objective To study the application value of CT axial scan and coronal scan in the clinical diagnosis and differential diagnosis of nasal sinus neoplasms.Methods 97 patients who underwent CT examination in E.N.T. department of our hospital from August 2013 to August 2015 were selected as the research objects. All patients underwent CT examination, including axial scan and coronal scan. Based on the pathological results, the diagnostic accuracy of different scanning methods was calculated and compared with the results of combined scanning. Meanwhile, the imaging features and key points of differentiation of benign and malignant nasal sinus neoplasms were summarized.Results The pathological results of 97 patients were 56 cases with benign neoplasms and 41 cases with malignant ones. The diagnostic accuracy of CT axial scan was 70.1% (68/97) while of coronal scan was 77.3% (75/97). There were no statistically significant differences between the two. The diagnostic accuracy of axial combined with coronal scan was 88.7% (86/97), which was significantly higher than that of CT axis and coronal scan, respectively. The difference was statistically significant (P<0.05), which indicated that the axial combined with coronal position was more valuable in diagnosis.Conclusion CT is a non-invasive and higher-resolution examination method which can directly display the size and range of lesions in nasal cavity and sinuses, tumor lesions, communication channels and situation around the lesions. It is helpful for early diagnosis and can provide useful information for making clinical treatment plan. Axial plain scan can be used as a supplement to coronal scan to obtain information such as bone destruction of sinus wall and surrounding tissue invasion and to further improve the diagnostic accuracy.
