The diagnostic value of 3.0T MRI in cesarean scar pregnancy.

Objective: The purpose was to evaluate the diagnostic value of 3.0T MRI in cesarean scar pregnancy (CSP).

Methods: 56 patients with suspected CSP treated in our hospital from August 2018 to July 2020 were recruited as the study cohort and diagnosed using ultrasound and 3.0T MRI. With the pathological examination results as the gold standard and the ultrasound examination results as a comparison, the diagnostic value of 3.0T MRI was evaluated according to the diagnostic accuracy, sensitivity, specificity, and positive and negative misdiagnosis rates, etc. Results: The pathological examination showed that 33 patients were positive for CSP but the other 23 were negative. The accuracy, sensitivity, and specificity of 3.0T MRI in the CSP diagnoses were significantly higher than the accuracy, sensitivity, and specificity of the ultrasound diagnoses (P<0.05), and the positive and negative misdiagnosis rates were significantly lower than the misdiagnosis rates of the ultrasound diagnosis (P<0.05). Moreover, the images from two patients showed that 3.0T MRI can provide clear images of the patients' lesion locations.

Conclusion: Compared with ultrasound diagnoses, 3.0TMRI has significant advantages in diagnosing CSP and has a high clinical value.
