A comparative study of the consistency of ultrasound with MRI on the diagnosis of uterine cesarean scar pregnancy / 中国实用妇科与产科杂志

ABSTRACT

OBJECTIVE: To explore the consistency of ultrasound with MRI on the diagnosis of uterine cesarean scar pregnancy（CSP）.METHODS: Retrospectively analyze the clinical data of 91 patients from January 2012 to June 2018 in Beijing Chaoyang Hospital and Beijing Luhe Hospital.RESULTS: The ultrasonic77 cases of CSP were clearly diagnosed（84.6%）,12 cases were suspicious for CSP（13.2%）and 2 cases were misdiagnosed（2.2%）.MRI showed that 90 cases of CSP were clearly diagnosed（98.9%）one case was misdiagnosed（1.1%）.Totally 32 cases were found to have yolk sac in ultrasonography,27 cases of them had fetal buds,and 20 cases of them had embryocardia-beats,while MRI could not distinguish the yolk sac from the fetal bud,and was unable to verify the embryocardia-beats.CONCLUSION: Ultrasonography can be used as the basis for screening and classification of CSP,which can help the early detection and the choice of treatment.The MRI images of CSP have certain specificity,which can provide more accurate imaging data for clinical diagnosis and treatment.3.The combination of ultrasound and MRI can significantly reduce the misdiagnosis of CSP.
