Abstract:

Objective: To assess the diagnostic accuracy of magnetic resonance imaging (MRI) in detecting invasive placentas using per-operative findings as the gold standard. Methodology: A prospective cross-sectional study was conducted in the diagnostic radiology department of KRL General Hospital Islamabad during Oct 2019 to Sep 2021. Sixty prenatal individuals were identified as having a high risk of invasive placenta and underwent MRI (Phillips 1.5 T) to confirm the diagnosis. A trainee radiologist and a consultant radiologist reviewed the images. The MRI's sensitivity, specificity, positive predictive value, negative predictive value, and accuracy was calculated using a 2×2 contingency tables. Results: Ten cases of invasive placenta were detected postoperatively (gold standard). The MRI had a sensitivity of 90%, a specificity of 93%, a positive predictive value of 90%, a negative predictive value of 90%, and an accuracy of 92.3 percent, respectively. Conclusion: The study concluded that magnetic resonance imaging (MRI) offers a good diagnostic accuracy and is a reproducible technology for prenatal identification of invasive placentas.
