Methods: The ultrasound and MRI data of forty-five cases were selected from Weifang Maternal Child Health Hospital from 2015 January to 2022 January who were operatively proved as CAA. With retrospectively analysis, the diagnosic value of MRI and ultrasound was analyzed. A receiver operating characteristic (ROC) analysis was used to evaluate the diagnosis performance of the two modalities. Results: Among the 45 confirmed cases of CAA, 2 cases (4.44%) were high anal atresia, 37 cases (82.22%) were medial atresia, 6 cases (13.33%) were low atresia, according to the surgery results. Using the results of surgery results as the gold standard, the accuracy rate of MRI in the diagnosis of CAA was 97.78%, the sensitivity was 97.44%, the specificity was 100.00%, the positive predictive value was 100.00%, and the negative predictive value was 85.71%, which are significantly higher than those of ultrasound (77.78%, 84.62%, 33.33%, 89.19%, 25.00%) (P < 0.05). MRI diagnosis Kappa value is 0.829, the consistency intensity is high (P < 0.05). Ultrasound diagnosis Kappa value is 0.413, the consistency intensity is general (P < 0.05). The area under ROC curve (AUC) of MRI diagnosis 0.917 (95% CI 0.856~0.991), and the differences were statistically significant when compare with the ultrasound diagnosis 0.719 (95% CI 0.601~0.829). Conclusion: MRI has higher clinical application value compare with ultrasound in CAA diagnosis and has certain predictive value for the type of CAA.展开更多
