Assessment of placental abruption with diffusion‐weighted imaging

摘要

Abstract Aim To investigate whether placental abruption without fetal distress could be assessed by apparent diffusion coefficient (ADC) values in magnetic resonance imaging (MRI). Methods We conducted a retrospective case–control study at a single center. ADC values at the lesions of placental abruption in the abruption group (n?=?8) were compared to those in the control group (n?=?32). In the abruption group, ADC values at the sites of abruption were also compared to those at the nonabruption sites within the same placenta. Results The ADC values in the placental area above the abruption site in the abruption group showed lower values than those in the control group when the slice containing the umbilical cord insertion site was set as the reference, and those values were compared in each corresponding slice. Compared with average ADC values, those above the abruption site in the abruption group were also significantly lower than those in the control group (p?
