Abstract: The diagnostic effects of transabdominal ultrasound combined with magnetic resonance imaging (MRI) on patients of pernicious placenta previa were analyzed in this study. 270 patients with PPP were selected as subjects. The effects of transabdominal ultrasound, MRI and the combined diagnosis were compared. The detection rate of combined group was significantly higher than that of transabdominal ultrasound group and MRI group (P<0.05). The coincidence rate and overall accuracy of the combined diagnosis were higher than those of the ultrasound and MRI groups. There were significant differences in the delivery methods of the groups (P<0.05), but there were no significant differences in the surgical treatment methods and the amount of blood transfusion (P>0.05). Compared with the ultrasound group and the MRI group, the incidence rates of hematorrhea and shock in the combined group was significantly different (P<0.05), but the rates of premature delivery and neonatal asphyxia were lower in the combined group than in the other groups (P>0.05). In conclusion, transabdominal ultrasound combined with MRI can improve the detection rate of PPP and improve pregnancy outcome.
