Greyscale ultrasonography of the placenta was performed in 54 primigravidae with placentas located on the anterior wall of the uterus, in a longitudinal study. During pregnancy single and multiple 'nodular increased transsonity' was seen echoscopically in the placenta. After birth these findings proved to be highly correlated to 'intervillous thrombosis'. The clinical value of these findings is discussed.
在一项纵向研究中，对54例胎盘位于子宫前壁的初产妇进行了胎盘灰阶超声检查。在孕期，超声检查发现胎盘内有单个和多个“结节状透声增强”。产后这些发现被证明与“绒毛间隙血栓形成”高度相关。文中讨论了这些发现的临床价值。
