目的:研究探讨在女性盆腔囊性占位病变诊断中核磁共振成像(MIR)的实效性。方法:对从2008年6月至2013年6月在杭州市余杭区第一人民医院经手术病理确诊的70例盆腔囊性占位病变的女性患者,进行MRI和超声检查进而比较二者的准确率,并进一步分析通过MRI检查不同种类的盆腔囊性占位病变的相应特点。结果在70例病例中,共有69例通过MRI检查诊断为盆腔囊性占位病变,病灶部位与病理诊断符合,准确率达98.55%,且这70例病例中经手术病理确诊出25例恶性肿瘤有24例经MRI检查被诊断出,准确率达96%;超声检查诊断出盆腔囊性占位病变共计63例,准确率90.00%,其中手术病理确诊的25例恶性肿瘤,经超声检查诊断出19例,准确率76%,两种方法之间的两组数据均具有统计学意义(P<0.05)。盆腔囊性占位病变在MRI检查下各有特点:子宫肌瘤一般会出伴随积增大、宫旁肿块,另外会有T1WI低信号;子宫腺肌症除了表现为体积增大之外,低信号的T1WI以及混杂信号的T2WI亦是其重要表现;宫颈癌则伴随有宫颈增大、低信号T1WI、中等信号T2WI。结论相对目前应用更多的超声检查而言,MRI能够更准确地诊断出盆腔囊性占位病变、更准确的定位盆腔病灶,而且能更准确的定性判断肿瘤的良恶性。
Objective: To investigate the effectiveness of magnetic resonance imaging (MIR) in the diagnosis of pelvic cystic lesions in women. Methods: From June 2008 to June 2013, 70 female patients with pelvic cystic lesions confirmed by surgical pathology in the First People’s Hospital of Yuhang District, Hangzhou City were examined by MRI and ultrasonography to compare the accuracy of the two Rate, and further analysis of the corresponding characteristics of different types of pelvic cystic lesions examined by MRI. Results In 70 cases, a total of 69 cases were diagnosed as pelvic cystic lesions by MRI, the site of the lesions was consistent with the pathological diagnosis, the accuracy rate was 98.55%, and in the 70 cases, 25 cases of malignant tumors were confirmed by operation and pathology 24 cases were diagnosed by MRI, the accuracy rate was 96%; ultrasonography diagnosis of pelvic cystic lesions in a total of 63 cases, the accuracy rate of 90.00%, of which 25 cases of surgical pathological diagnosis of malignant tumors diagnosed by ultrasound 19 cases, accuracy rate of 76%, two sets of data between the two methods were statistically significant (P <0.05). Pelvic cystic lesions in the MRI examination has its own characteristics: uterine fibroids generally will be accompanied by increased product, parathyroid mass, there will be a low signal T1WI; adenomyosis in addition to the performance of the volume increase, low Signal T1WI and mixed signal T2WI is also an important manifestation of cervical cancer is accompanied by cervical enlargement, low signal T1WI, moderate signal T2WI. Conclusions Compared with the current application of more ultrasound examination, MRI can more accurately diagnose the pelvic cystic lesions, more accurately locate the pelvic lesions, and can more accurately determine the qualitative and quantitative benign and malignant tumors.
