ULTRASOUND EXAMINATION OF THE PLACENTAL BLOOD CIRCULATION LIMITS AND PERSPECTIVES
Abstract:
Placenta, this organ with a particular vascular structure, by the functional integrity of which
depends the birth of a new life, was the subject of numerous researches over time. Conventional twodimensional
(2D) ultrasound, color/power and pulsed Doppler have been widely used for the structural
and functional evaluation of the placenta during pregnancy. 3D ultrasound through modern techniques
of power Doppler (3DPD) such as angiography and histogram analysis makes possible the qualitative
and quantitative assessment of vascularization, flow and placental perfusion. 3D ultrasound may be
important in the evaluation of feto-placental insufficiency in clinical practice, and in the prediction of
fetal growth restriction and pre-eclampsia, although some limitations regarding the assessment of the
placenta using 3D ultrasound still remain unresolved.
