经阴道超声与核磁共振成像在非肿瘤性卵巢疾病诊断中的比较

Comparison in the diagnostic efficiency for non-neoplastic ovarian diseases between transvaginal ultrasonography and magnetic resonance imaging examination

目的比较经阴道超声与核磁共振成像检查在诊断非肿瘤性卵巢疾病的效率差异。方法分析及对比228例非肿瘤性卵巢疾病患者经阴道超声与核磁共振成像检查的确诊率、误诊率和漏诊率。结果 228例中属子宫内膜异位囊肿90例、卵巢异位妊娠55例、输卵管卵巢脓肿32例、卵巢破裂26例、卵巢囊肿蒂扭转25例。核磁共振成像对子宫内膜异位囊肿、卵巢异位妊娠、输卵管卵巢脓肿的确诊率明显高于经阴道超声检查,对子宫内膜异位囊肿、输卵管卵巢脓肿的误诊率低于经阴道超声检查(均P<0.05)。结论经阴道超声与核磁共振成像检查非肿瘤性卵巢疾病均适合作为诊断卵巢疾病的方法,但核磁共振成像在部分非肿瘤性卵巢疾病的诊断优于经阴道超声。

Objective To explore the difference in diagnostic efficiency for non-neoplastic ovarian diseases between transvaginal ultrasonography and magnetic resonance imaging examination.Methods 228 cases confirmed with nonneoplastic ovarian diseases have undergone transvaginal ultrasonography and magnetic resonance imaging examination.The clinical efficiency of transvaginal ultrasonography and magnetic resonance imaging examination was analyzed and compared in terms of accuracy rate,misdiagnosis rate and rate of missed diagnosis.Results Among 228 cases,there were 90 cases with endometrial cyst,55 cases with ectopic ovarian pregnancy,32 cases with tubo-ovarian abscess,26 cases with ovarian rupture,and 25 cases with ovarian cyst torsion.Magnetic resonance imaging examination had a significantly higher accuracy rate in diagnosing endometrial cyst,ectopic ovarian pregnancy and tubo-ovarian abscess and a lower misdiagnosis rate in diagnosing endometrial cyst and tubo-ovarian abscess compared with transvaginal ultrasonography(P<0.05).Conclusion Both transvaginal ultrasonography and magnetic resonance imaging examination are applicable for diagnosing ovarian diseases.However,magnetic resonance imaging examination is superior to transvaginal ultrasonography in the diagnosis of nonneoplastic ovarian diseases.
