Value of transvaginal ultrasound combined with 3.0T magnetic resonance imaging for the diagnosis of ectopic pregnancy
Objective To compare the value of transvaginal ultrasound,3.0T magnetic resonance imaging(MRI)scan-ning alone and in combination for diagnosis of ectopic pregnancy,so as to provide insights into early screening of ectopic pregnancy.Methods This study enrolled a total of 130 patients with suspected ectopic pregnancy admitted to Dachuan People's Hospital in Dazhou City,Sichuan Province,China between February 2019 and December 2022.All patients under-went transvaginal ultrasound examination and 3.0T MRI scanning.The consistency of transvaginal ultrasound and 3.0T MRI with clinical diagnostic results was evaluated with surgical pathology or clinical follow-up results as the golden standards.The sensitivity,specificity,and accuracy of transvaginal ultrasound and 3.0T MRI,alone and in combination,were com-pared for diagnosis of ectopic pregnancy.Results Of the 130 patients with suspected ectopic pregnancy,108 cases were confirmed with ectopic pregnancy by surgical pathology,and 22 cases were confirmed without ectopic pregnancy by clinical follow-up.The sensitivity,specificity,and accuracy of transvaginal ultrasound were 85.19％(92/108),54.55％(12/22),and 80.00％(104/130),respectively,with 0.358 consistency with clinical diagnostic results.The sensitivity,specificity,and ac-curacy of 3.0T MRI were 92.59％(100/108),81.81％(18/22),and 90.77％(118/130),respectively,with 0.694 consistency with clinical diagnostic results.The sensitivity,specificity,and accuracy of transvaginal ultrasound combined with 3.0T MRI were 98.15％(106/108),72.73％(16/22),and 93.85％(122/130),respectively,with 0.764 consistency with clinical diagnost-ic results.In addition,the sensitivity and accuracy of transvaginal ultrasound combined with 3.0T MRI were significantly higher than transvaginal ultrasound alone for diagnosis of ectopic pregnancy(x2=11.88 and 10.96,both P＜0.01).Conclusion Transvaginal ultrasound combined with 3.0T MRI may provide more diagnostic information for ectopic preg-nancy,and is highly consistent with the clinical diagnostic results.In addition,transvaginal ultrasound combined with 3.0T MRI improves the diagnostic sensitivity and accuracy for ectopic pregnancy than transvaginal ultrasound alone.
