Research on the value of MRI scanning technology in the diagnosis of cervical cancer patients
宫颈癌患者诊断中应用MRI扫描技术的价值研究

摘要

目的 了解对宫颈癌患者的诊断中磁共振成像（MRI）扫描的应用价值，探究其对病灶检出率、局部淋巴结分期以及周围组织侵犯程度的评估作用等临床意义。方法 选择经我院治疗并诊断为宫颈癌的患者共80人进行妇科查体检查、B超检查以及MRI扫描检查，并以术后的病理检测或者穿刺活检为诊断的金标准。统计分析MRI对宫颈癌病灶发现情况、分期识别准确率和宫旁浸润、阴道受侵、淋巴结转移等征象的显示程度，对比MRI图像学改变与病理检测结果是否一致。结果 MRI能清楚地显示出宫颈癌原发部位，对于肿瘤组织与宫颈间质之间的区分有很好的效果，其对于病灶定位、肿瘤大小测量及盆腔内转移判定效果明显。其诊断准确率高于普通超声，对于Ia期微灶有一定的限制性，但是对于Ib期以上的病变来说分级的意义较大。而宫旁浸润、阴道上段受侵及盆腔淋巴结异常的检出率高，准确性好，有助于临床制定手术计划以及放疗照射范围。结论 MRI成像检查手段在宫颈癌诊断上有较好的临床作用，不仅可以增加病灶检出数目还可以较为精确地测定肿瘤浸润程度以及临床分期，对于指导个体化治疗策略的选择、判定疗效与预测患者远期结局均有一定的帮助意义。

Abstract

Objective To understand the application value of Magnetic Resonance Imaging (MRI) scanning in the diagnosis of cervical cancer patients, and to explore its clinical significance in the detection rate of lesions, local lymph node staging, and the degree of invasion of surrounding tissues.
Methods A total of 80 patients diagnosed with cervical cancer in our hospital were selected for gynecological examination, B-ultrasound examination, and MRI scanning. The pathological detection or puncture biopsy after surgery was used as the diagnostic gold standard. Statistical analysis was conducted on the detection of cervical cancer lesions by MRI, the accuracy of stage identification, and the display degree of adjacent infiltration, vaginal invasion, and lymph node metastasis. The consistency between MRI imaging changes and pathological detection results was compared.
Results MRI can clearly show the primary site of cervical cancer, has a good effect in distinguishing tumor tissue from cervical stroma, and has obvious effects on lesion localization, tumor size measurement, and determination of pelvic metastasis. Its diagnostic accuracy is higher than that of ordinary ultrasound, but has certain limitations for Ia stage microfoci. However, for lesions at Ib stage and above, it has greater significance for grading. The detection rate and accuracy of adjacent infiltration, upper vaginal invasion, and abnormal pelvic lymph nodes are high, which is helpful for clinical formulation of surgical plans and radiotherapy irradiation range.
Conclusion   MRI imaging examination methods have a good clinical effect in the diagnosis of cervical cancer. It can not only increase the number of lesion detections but also accurately measure the degree of tumor invasion and clinical staging. It is of certain help in guiding the selection of individualized treatment strategies, judging efficacy, and predicting the long-term prognosis of patients.
