MRI对宫颈癌及邻近侵犯结构的诊断价值

THE DIAGNOSTIC VALUE OF MRI IN CERVICAL CANCER AND ADJACENT VIOLATED STRUCTURES

目的:探讨MRI对宫颈癌及邻近侵犯结构的诊断价值。方法:选择宫颈癌患者36例,接受MRI检查,以术后病理结果为金标准,分析本组宫颈癌患者的MRI表现、邻近结构侵犯情况以及不同病理分期患者的MRI分期情况。结果:36例宫颈癌患者,14例不规则形肿块、22例圆形肿块或结节,T_2WI显示中高信号33例,T_2WI显示等信号3例;T_1WI显示等信号22例,显示略低信号14例;宫颈内肿块影16例,前唇局限结节6例,后唇局限结节11例,右侧及前唇受侵3例;MRI IV期、III期、II期以及Ib期的诊断准确率分别为100%(3/3)、87.50%(7/8)、95.23%(20/21)以及75.00%(3/4)。结论:MRI对宫颈癌患者分期有较高的诊断准确率,在宫颈癌及其邻近侵犯结构诊断中具有重要价值。

Objective： To explore the diagnostic value of MRI in cervical cancer and adjacent violated structures. Methods： Thirty-six patients with cervical cancer underwent MRI diagnosis to pathology results as the gold standard, then taken the analysis for cervical MRI manifestation of cancer, as well as violations of adjacent structures different pathological staging in patients with MRI staging situation. Results： In 36 cases of cervical cancer, 14 cases showed irregular-shaped mass, and 22 cases round lumps or nodules; 33 cases were showed high signal in T2WI, and 3 cases equal signal; 22 cases were displayed equal signal in T1WI, and 14 cases slightly lower signal; 16 cases showed cervical mass, 6 cases nodules confined to the front lip, 11 cases rear lip limitations nodules, and 3 cases the right side and front lip invasion. MRI diagnostic accuracy rates in Ⅳ phase, Ⅲ phase, Ⅱ and phase Ib were 100% （3/3） , 87.50% （7/8） , 95.23% （20/21） and 75.00% （3/4） respectively. Conclusion： MRI has high diagnostic accuracy in patients with cervical cancer, with greatly important diagnostic value in adjacent violated structures
