Value of MRI for identifying dangerous placental placenta / 医疗卫生装备

ABSTRACT

Objective To discuss the value of MRI for identify dangerous placental placenta.Methods Totally 60 dangerous placental placenta patients hospitalized from May 2014 to July 2017 were selected, who underwent ultrasound and MRI examinations along with 60 patients with non-dangerous placental placenta.SPSS 22.0 software was used for data processing. Results The sensitivity, specificity and accuracy for identifying dangerous and non-dangerous placental placenta were respectively 80.00%,76.67% and 78.33% by ultrasound,86.67%,83.33% and 85.00% by MRI,and 96.67%,95.00% and 95.83% by combined ultrasound and MRI.The sensitivity,specificity and accuracy by combined ultrasound and MRI were significantly higher than those by ultrasound or MRI (P<0.05).Conclusion Ultrasound and MRI can both effectively identify non-dangerous and dangerous placental placenta, and higher-efficiency identification can be gained when ultrasound is combined with MRI. MRI can be a supplementary means when ultrasound is proved to not so satisfactory to identify dangerous placental placenta.
