Abdominal MRI and CT examination are not more accurate, each examination has different focus and different advantages. 1. Abdominal MRI is generally used to determine the type of tumor, has high resolution of soft tissue in the abdomen, and is able to image in many ways and from many angles, so it is more accurate than CT in the examination of benign and malignant tumors in the abdomen. 2. Abdominal CT: Abdominal CT can effectively diagnose abdominal inflammation, stones, digestive perforation and abdominal tumors, etc. with high accuracy, but it can not accurately judge whether the type of abdominal tumor is benign or malignant. It is recommended that patients go to the hospital and describe their specific conditions to the doctor, so that the doctor can choose the appropriate professional examination.
