Abstract:
Objective To investigate the application value of MRI in the diagnosing and assessing the severity of acute pancreatitis (AP).Methods 78 cases suspected with AP in our hospital underwent MRI.According to the golden standard of combination with the observation of the patients during hospitalization and the surgical pathological results,the sensitivity,accuracy and specificity of MRI in diagnosing AP were calculated.MRI Balthazar scoring system was used to evaluate the severity grade of AP.The results were compared with Ranson evaluation criterion usually used in clinic to evaluate the severity of AP.Results A total of 64 patients were final diagnosed by means of clinic and pathology.The sensitivity,accuracy and specificity of the MRI were 95.31％(61/64),93.59 ％ (73/78) and 85.71％(12/14),respectively.With the clinical and pathological diagnosis,the patient with mild AP were 45 cases,and the severe AP were 19 cases.The accuracy of MRI Balthazar severity grading was 95.31％ (61/64),which was significantly higher than that of Ranson evaluation accuracy 82.81 ％(53/64),with P =0.023.Conclusion MRI is an effective method for clinical diagnosis of AP,and it is superior to Ranson evaluation criterion for assessment of the severity,of which has a significant role in guiding clinical diagnosis and treatment.
