MRI与DWI在女性盆腔囊实性病变诊断中的应用

Application of MRI And DWI in the Diagnosis of Female Pelvic Cystic-solid Lesions

目的探究磁共振(MRI)与磁共振扩散加权成像(DWI)在女性盆腔囊实性病变诊断中的应用效果。方法回顾性分析我院284例女性盆腔囊实性病变患者临床资料。记录284例患者手术病理检查结果,评估MRI常规序列与DWI对女性盆腔囊实性病变的诊断价值,并比较不同性质病变的表观弥散系数(ADC)差异。结果284例患者共检出302个肿块,其中良性107个(35.43%),恶性195个(64.57%)。MRI常规序列诊断女性盆腔囊实性病变准确247个(81.79%),DWI诊断女性盆腔囊实性病变准确271个(89.74%),MRI常规序列诊断女性盆腔囊实性病变准确率明显低于DWI(P<0.05)。良性病变实性部分ADC明显高于恶性病变(P<0.05);但良性病变与恶性病变的囊性部分ADC比较,差异无统计学意义(P>0.05)。结论MRI常规序列及DWI均能诊断女性盆腔囊实性病变性质,但联合DWI诊断准确性更高,具有较高临床使用价值。

Objective To explore the application of magnetic resonance imaging(MRI)and magnetic resonance diffusion-weighted imaging(DWI)in the diagnosis of female pelvic cystic-solid lesions.Methods The clinical data of 284 female patients with pelvic cystic-solid lesions in our hospital were retrospectively analyzed.The results of surgical pathology examination were recorded in 284 patients,and the diagnostic value of conventional MRI sequence and DWI on female pelvic cystic-solid lesions was evaluated,and the apparent diffusion coefficient(ADC)of lesions with different natures was compared.Results A total of 302 masses were detected in 284 patients,including 107 benign masses(35.43%)and 195 malignant masses(64.57%).247 masses(81.79%)were accurate by MRI routine sequence in the diagnosis of female pelvic cystic-solid lesions,and 271 masses(89.74%)were accurate by DWI in the diagnosis of female pelvic cystic-solid lesions,and the accuracy rate of MRI routine sequence was significantly lower than that of DWI in the diagnosis of female pelvic cystic-solid lesions(P<0.05).The ADC of solid part of benign lesions was significantly higher than that of malignant lesions(P<0.05).However,there was no significant difference in the ADC of cystic part between benign lesions and malignant lesions(P>0.05).Conclusion MRI routine sequence and DWI can diagnose the natures of female pelvic cystic-solid lesions,but combined DWI has higher diagnostic accuracy and higher clinical application value.
