摘要
目的:分析磁共振(MRI)盆腔平扫+增强扫描在宫颈癌诊断及术后随访中的应用价值。方法:选取52例宫颈癌患者(宫颈癌组)及30名同期排除宫颈病变的健康体检者(正常组),分析其MRI盆腔平扫、增强扫描结果,比较不同分期、分化程度、不同预后患者各参数,并与病理结果进行对照,分析盆腔平扫+增强扫描在宫颈癌术后随访中的价值。结果:宫颈癌组的容量转移及速率常数(K^(trans)、K_(ep))、血管外细胞外容积分数(V_(e))均高于正常组(t=24.280、24.404、13.105,P<0.05);宫颈癌组中,随FIGO临床分期增加、分化程度降低,K^(trans)、K_(ep)、V_(e)呈增加趋势(P<0.05);手术清扫盆腔淋巴结78枚,转移性淋巴结在形态、长径、短径、周围脂肪间隙、强化程度方面与非转移性淋巴结均有差异(P<0.05);术后预后良好组K^(trans)、K_(ep)、V_(e)均低于预后不良组(t=7.063、7.601、5.701,P<0.05);以病理结果为准,MRI盆腔平扫+增强扫描预测预后不良的敏感度、特异度、准确度、Kappa值分别为88.57%、88.24%、88.46%、0.768。结论:MRI盆腔平扫+增强扫描在宫颈癌的诊断及术后随访中均有较高应用价值,值得临床推广实践。
Objective:To analyze the application value of pelvic magnetic resonance imaging(MRI)plain scan combined with enhanced scan in the diagnosis and postoperative follow-up of cervical cancer.Methods:52 patients with cervical cancer(cervical cancer group)and 30 health checkups(normal group)excluding cervical diseases were selected.The results of pelvic MRI plain scan and enhanced scan were analyzed.The parameters of patients in different stages,with different differentiation degrees,and different prognosis were compared.Pathological results were used to analyze the value of pelvic plain scan combined with enhanced scan in postoperative follow-up of cervical cancer.Results:The volume transfer constant and rate constant(K^(trans),K_(ep)),and extravascular extracellular volume fraction(V_(e))in the cervical cancer group were higher than those in the normal group(t=24.280,24.404,13.105,P<0.05).These parameters increased with the increase of FIGO stage and decrease of differentiation degree(P<0.05).78 pelvic lymph nodes were removed by surgery.The metastatic lymph nodes were significantly different from non-metastatic lymph nodes in terms of morphology,long diameter,short diameter,surrounding fat space,and enhancement degree(P<0.05).K^(trans),K_(ep),and V_(e) in the good prognosis group were lower than those in the poor prognosis group(t=7.063,7.601,5.701,P<0.05).The sensitivity,specificity,accuracy and Kappa value of MRI plain scan combined with enhanced scan to predict poor prognosis were 88.57%,88.24%,88.46%and 0.768,respectively.Conclusion:Pelvic MRI plain scan combined with enhanced scan is helpful for diagnosis and postoperative follow-up of cervical cancer,which is worthy of clinical promotion.
