Accuracy of magnetic resonance imaging in diagnosing morbidly adherent placenta
Objectives: To determine the accuracy of magnetic resonance imaging (MRI) in diagnosing morbidly adherent placenta, taking surgical findings as gold standard.
Methods: In this cross-sectional descriptive study, a total of 107 patients with suspected morbidly adherent placenta (MAP) and ages between 20-40 years underwent MRI pelvis. Images were assessed by an experienced radiologists for presence or absence of morbidly adherent placenta (MAP). All patients later had surgery and operative findings were compared with MRI findings. Data was analyzed by IBM SPSS Statistics for Windows, version 21.0. Armonk, NY.
Results: Age range of the patients was from 20-40 years with the mean age of 28.31 ± 3.86 years. Most of the patients 87 (81.31%) were between ages 20 to 30 years. In 60 MRI positive cases, 53 were true positive and other 07 were false positive. In 47 MRI negative patients, 40 were true negative and 07 were false negative. Overall sensitivity, specificity and diagnostic accuracy of MRI in diagnosing MAP, taking operative findings as gold standard was 88.33%, 85.11% and 86.92% respectively.
Conclusion: Magnetic resonance imaging (MRI) is an excellent modality with highly sensitive and accurate modality for diagnosing morbidly adherent placenta (MAP).
