目的探讨MRI在子宫颈癌诊断、治疗及预后中的临床意义。方法回顾性分析河南省开封市第一人民医院经病理证实的45例子宫颈癌患者MRI表现、诊断及分期,将MRI诊断结果与病理诊断比较。结果 40例MRI发现了病灶。在T1W I宫颈癌与周围宫颈组织相比呈等信号,在T2W I,宫颈癌呈稍高于正常宫颈组织。具有宫旁浸润时,显示为癌肿周围正常低信号带中断或消失,Gd2DTPA增强后肿瘤组织不同程度强化。28例经单纯放疗,9例肿瘤信号完全消失,17例肿瘤不同程度缩小,局部T2W I序列呈低信号,出现不同程度无强化区,2例无变化。结论 MRI能准确显示子宫肿瘤病灶,并多方位观察癌肿侵犯范围,分期客观准确,对临床制订治疗方案及预后评估具有重要指导意义。
Objective To investigate the clinical significance of MRI in the diagnosis, treatment and prognosis of cervical cancer. Methods The MRI findings, diagnosis and staging of 45 cervical cancer patients confirmed by pathology were retrospectively analyzed. The diagnostic results of MRI were compared with the pathological diagnosis. Results 40 cases of MRI found lesions. In T1W I cervical cancer compared with the surrounding cervical tissue was equal signal in T2W I, cervical cancer was slightly higher than normal cervical tissue. With paracancerous infiltration, the normal low signal band around the cancer showed interruption or disappearance of the Gd2DTPA enhanced tumor tissue enhanced to varying degrees. Twenty-eight patients underwent complete radiotherapy. Nine cases of tumor completely disappeared. Seventeen cases of tumors were reduced to varying degrees. Local T2W I sequence showed low signal, with no enhancement in different degree and no change in two cases. Conclusion MRI can accurately show the uterine tumor lesions, and multi-directional observation of the extent of cancer violations, staging objective and accurate, clinically important for the development of treatment options and prognosis evaluation.
