ABSTRACT
Objective:
To analyze the ultrasonography and MRI characteristics of placenta increta and to compare and analyze the value of ultrasonography and MRI for the diagnosis of placenta increta.Methods:
From November, 2012 to October 2014, 56 patients with suspected placenta increta were selected as the objects of experiment. All patients were examined by ultrasound and MRI before the surgery. The ultrasound and MRI image features were retrospectively analyzed and summarized its detection. The reliability and accuracy of detection were compared and analyzed.Results:
The visible vortex in the placenta, disappearance of placenta back clearance, local thinning of muscularis and placental pathologic thickening were the main characters of ultrasound images. The boundary wavy, placental thickness heterogeneity, signal heterogeneity, the interface and serosal signal loss or interruption and vascular rich were the main characters of MRI. For ultrasonography, there were 17 cases accurate detection, the sensitivity was 89.47%, the specificity was 92.60%, the precision ratio was 92.86%, the diagnostic index was 85.18%. For MRI, there were 18 cases accurate detection, the sensitivity was 94.74%, specificity was 96.30%, the precision ratio was 96.43%, the diagnostic index was 92.60% and Kappa value was 0.86, after the data comparison of two groups, (Kappa=0.86, P>0.05), there was no significant difference.Conclusion:
The ultrasound and MRI were the important means of clinical diagnosis of placenta increta, and their diagnostic value cannot be replaced by each other. To take advantages of both was suggested and a more accurate and reliable diagnosis can be made.
