Background: In addition to ultrasound, magnetic resonance imaging (MRI) also helps in prenatal diagnosis of the adherent placenta and ultimately reduces maternal mortality and morbidity. There have also been several studies in Western countries regarding the prenatal diagnosis of adherent placentas on imaging, but there are few in Pakistan. The objective of this study is to investigate the diagnostic accuracy of MRI in invasive placentation in comparison with histopathology.

Methodology: From July 2021 to December 2021, a cross-sectional prospective study was conducted in the Radiology Department at Hayatabad Medical Complex Peshawar Pakistan. In this study, 60 antenatal patients with adherent placentas who were clinically suspected to be high-risk were included. In this study, MRI was used to diagnose adherent placenta with sensitivity and specificity.

Results: Results showed that 20 patients had accurate MRI diagnosis of adherent placentas, while 4 patients missed the diagnosis, resulting in 83.3% sensitivity and 77.7% specificity.

Conclusion: Using the results of our study, radiologists will be able to increase the accuracy of their workup of high-risk patients and enhance multidisciplinary delivery planning to improve maternal outcomes.
