Second, general outpatients, generally depending on the size of the hospital and the amount of patients in 2-4 hours after taking the results. Third, inpatients, depending on the time of the examination and the volume of patients to decide, the morning examination results in the afternoon, the afternoon examination results are generally taken the next day, if it is a hospital with a small amount of patients, the report results are usually returned to the ward on the same day. The CT examination is not done by the machine and the results come out, but the diagnosing doctor has to read the film and write the report, and the superior doctor will review it and then release it, so the patient needs to wait patiently after the CT examination.
