THE VALUE OF ULTRASOUND AND MAGNETIC RESONANCE IMAGING IN DIAGNOSIS OF PLACENTA PREVIA AND ABNORMAL PLACENTATION
Abstract
Background: Maternal morbidity and mortality are significantly increased in cases with placenta accreta spectrum (PAS), a severe obstetric disease. Accurate antenatal diagnosis is essential for optimal peripartum planning and management. Using intraoperative and histological findings as the gold standard, this study aimed to evaluate and compare the diagnostic accuracy of magnetic resonance imaging (MRI) and ultrasound in detecting PAS.
Materials & Methods: From the 1st of March, 2023 to the 1st of August, 2025, Radiology, Obstetrics & Gynaecology, a validational cross-sectional study was conducted at Rehman Medical Institute and Hayatabad Medical Complex. We conducted a study on 146 pregnant women with 28 weeks soaring pregnancy age and history of abnormal placentation using non-probability consecutive sampling technique. MRI and USG values were standardised in all the subjects. The calculated sensitivity, specificity, positive predictive value, negative predictive value and accuracy were used for the assessment. The SPSS ver 26.0 analyzed the information statistically, and p0.05 is significant.
Results: On average, participants were 32.47 ± 6.66 years old and 32.79 ± 3.28 weeks pregnant. A clinical diagnosis of PAS was confirmed in 99 (67.8%) cases. The diagnostic accuracy of ultrasound for probable infective pyelonephritis and UTI was found to be 82.19%. The results of the MRI analysis improved.
Conclusion: When it came to recognizing the placenta accreta spectrum, MRI proved to be more accurate than ultrasound. In high-risk pregnancies, magnetic resonance imaging (MRI) is a useful adjunct to ultrasound for enhancing diagnostic certainty and facilitating right surgical planning, while ultrasound is still the gold standard.
