TUI 3D in Diagnosis of Placenta Accreta: Comparison With Gray-scale and Color Doppler Techniques
- Conditions
- Placenta Accreta
- Registration Number
- NCT02712099
- Lead Sponsor
- Ain Shams University
- Brief Summary
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.
- Detailed Description
* 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 :
1. History taking
2. Clinical examination.
3. 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.

- Secondary Outcome Measures
Name Time Method Crowded Vessels Over Peripheral Sub-placental Zone by 3D Tomographic Ultrasound Imaging (TUI) 28 -36 weeks of gestation the examiner can simultaneously display, on the monitor or on a hard copy, up to 24 preselected parallel cuts from a volume. The slices can be generated either along the initial or any other reconstructed plane of the region of interest (ROI) in intervals of 0.5 - to 5 mm segments. Slice thickness will be adjusted as necessary for each individual case. The most informative image among the multiple images will be displayed with the use of CrossXBeam, a postprocessing tool that allows one to enhance tissue and border differentiation, leading to sharper depiction of the tissue margins
