Value of three dimensional color power Doppler ultrasound in diagnosis of placenta accrete / 医疗卫生装备

ABSTRACT

Objective To explore the diagnostic value of three-dimensional color Doppler ultrasonography (3D-PDU) three-dimensional reconstruction technique for placenta accrete. Methods Totally 65 cases of suspected patients with placenta implantation underwent 3D-PDU examination, then the examination results were compared with those by clinical or pathological method, and the results by clinical or pathological method were used as the gold standard. Results There were no significant differences between the results by 3D-PDU and the gold standard (P=0.754), and there was consistency between the two methods (Kappa=0.661,P<0.001). Conclusion 3D-PDU combined with 3D reconstruction technique contributes to displaying lesion structure, blood perfusion and etc and provides quantitative indexes to determine the depth and size of the accreted placenta, and thus is of great significance for the early diagnosis and treatment planning of the placenta accrete.
