The diagnostic value of MRI in placenta accrete patients

Abstract

Appropriate treatment in women with placenta accreta requires a definite preoperative diagnosis and a detailed explanation of the treatment plan, which is necessary to maintain the mother's safety during childbirth. Therefore, this study aimed to evaluate the sensitivity and specificity of MRI performed in placenta accreta, compare its results with intraoperative findings, and report pathology in hysterectomy cases. Materials and Methods: In this cohort study, all patients with suspected placenta accreta underwent MRI and reported placental infiltration. (Accreta, Increate, Percreta) Furthermore, in the case of hysterectomy, a pathology report was recorded regarding penetration depth. Results: Following delivery, placenta accreta was reported in 71% of patients. Placenta accreta and increate were the most common placental penetration into the uterine wall. In the sensitivity and specificity of color Doppler ultrasound and MR imaging in placenta accreta diagnosis, these values were 73% and 25% in color Doppler ultrasound and 74% and 100% in MR imaging, respectively. Depth of placental trophoblastic layer penetration in both imaging methods was compared with the pathology, and surgical results of patients reported MR imaging in 33% and color Doppler in 58% of patients matched the pathology results.
