简要总结
The purpose of this study is to evaluate the potential of the 3 D TUI view in diagnosis of morbidly adherent placenta in comparison to 2D grayscale, color Doppler and intraoperative findings.
详细描述
- This is a prospective study which will include 50 patients who will be selected from the outpatient and inpatient obstetric Ain Shams university maternity hospital.
- All patients will undergo the following :
- History taking
- Clinical examination.
- For each patient, the whole placenta will be scanned in a systematic fashion using both 2D grayscale and 2D power Doppler ultrasound then displayed by 3D TUI to determine whether those patients suspected of having advanced invasive placentation.
