摘要
目的:分析多模态磁共振成像(MRI)检查在子宫肌瘤诊断中的效能。方法:选取2022年1月至2023年6月该院收治的80例疑似子宫肌瘤患者进行横断面研究,入院后均进行常规MRI、动态增强MRI(DCE-MRI)、弥散加权成像(DWI)检查,统计常规MRI、DCE-MRI、DWI及多模态MRI检查对子宫肌瘤的诊断结果,并以手术病理检查结果为金标准,比较其在子宫肌瘤诊断中的效能及不同类型子宫肌瘤与非子宫肌瘤患者MRI参数水平。结果:手术病理检查结果显示,80例疑似子宫肌瘤患者中,62例子宫肌瘤,18例非子宫肌瘤;常规MRI检出54例子宫肌瘤,DCE-MRI检出58例子宫肌瘤,DWI检出58例子宫肌瘤,多模态MRI检出62例子宫肌瘤;多模态MRI检查诊断子宫肌瘤的准确度均高于常规MRI、DCE-MRI、DWI检查,灵敏度均高于常规MRI、DCE-MRI检查,阳性预测值、阴性预测值均高于常规MRI检查,差异有统计学意义(P<0.05);富细胞型患者容量转移常数(K^(trans))、速率常数(K_(ep))、血浆容积分数(V_(p))均高于非子宫肌瘤、普通型及退变型患者,血管外细胞外间隙容积分数(V_(e))高于退变型患者,ADC值低于普通型患者,差异均有统计学意义(P<0.05);退变型患者V_(e)均低于非子宫肌瘤、普通型患者,非子宫肌瘤、退变型患者ADC值均低于普通型患者,差异均有统计学意义(P<0.05);非子宫肌瘤、普通型、退变型患者K^(trans)、K_(ep)、V_(p)比较,差异均无统计学意义(P>0.05)。结论:多模态MRI检查在子宫肌瘤诊断中的效能均高于常规MRI、DCE-MRI和DWI检查。
Objective:To analyze efficiency of multimodal magnetic resonance imaging(MRI)in diagnosis of uterine fibroids.Methods:A cross-sectional study was conducted on 80 patients with suspected uterine fibroids admitted to the hospital from January 2022 to June 2023.Conventional MRI,dynamic contrast-enhanced MRI(DCE-MRI)and diffusion weighted imaging(DWI)were performed after admission.The diagnostic results of conventional MRI,DCE-MRI,DWI and multimodal MRI for uterine fibroids were statistically analyzed.Using the results of surgical pathological examination as the gold standard,The efficiency in the diagnosis of uterine fibroids and the levels of MRI parameters in the patients with different types of uterine fibroids and non-uterine fibroids were compared.Results:The surgical pathological examination showed that among the 80 patients with suspected uterine fibroids,62 cases were diagnosed as uterine fibroids,and 18 cases were diagnosed as non-uterine fibroids;conventional MRI detected 54 cases of uterine fibroids;DCE-MRI detected 58 cases of uterine fibroids;DWI detected 58 cases of uterine fibroids;multimodal MRI detected 62 cases of uterine fibroids.The accuracy of multimodal MRI in the diagnosis of uterine fibroids was higher than that of conventional MRI,DCE-MRI and DWI;the sensitivity was higher than that of conventional MRI and DCE-MRI;the positive predictive value and the negative predictive value were higher than those of conventional MRI;and the differences were statistically significant(P<0.05).The volume transfer constant(K^(trans)),rate constant(K_(ep))and fractional plasma volume(V_(p))of the patients with cellular leiomyoma were higher than those of the patients with non-uterine fibroids,common type and degenerative type,the extravascular extracellular volume fraction(V_(e))was higher than that of the patients with degenerative type,the ADC value was lower than that of the patients with common type,and the differences were statistically significant(P<0.05).The V_(e) of the patients with degenerative type was lower than that of the patients with non-uterine fibroids and common type;the ADC values of the patients with non-uterine fibroids and degenerative type were lower than those of the patients with common type;and the differences were statistically significant(P<0.05).However,there were no significant differences in the K^(trans),K_(ep) and V_(p) among the patients with non-uterine fibroids,common type and degenerative type(P>0.05).Conclusions:The efficiency of multimodal MRI in the diagnosis of uterine fibroids is higher than that of conventional MRI,DCE-MRI and DWI.
