Abstract
Background: To highlighten the role of Magnetic Reso-nance Imaging (MRI) in detecting abnormal placentation.
Aim of Study: To determine the role of MRI in diagnosis of abnormal placentation comparing the results with post-operative and/or histopathological results.
Patient and Methods: Thirty three females patient were referred to MRI Unit with suspected placenta accreta by transabdominal ultrasound or showed inconclusive findings. MRI was done and the MRI diagnosis was compared to post partum findings and histopathological result.
Results: Twenty three patients (69.7%) had MRI diagnosis of abnormal placentation, 15 cases were diagnosed as placenta accreta and increta (45%), seven cases diagnosed as placenta percreta (21.2%), while ten cases (30.3%) were placenta previa without accreta. One case diagnosed as ectopic preg-nancy (3%). Twenty one cases proved to have placental invasion either intra operative finding and/or by histopatho-logical data, 13 cases (3 9.4%) had placenta accreta and increta, 7 cases (21.2%) had placenta percreta (21.2%) & one ectopic on CS scar (3%).
MRI shows sensitivity and specificity of 100% & 83.33% respectively.
Conclusion: Magnetic resonance imaging hand in hand with ultrasound is important for the accurate diagnosis of abnormal placentation. Co-operation of both modalities may provide more diagnostic information in ultrasound doubtful cases.
