The orthopedic examination can be divided into X-ray examination, CT examination and MRI examination, and the simple examination time is about 2 minutes for X-ray examination, 5 minutes for CT examination and 10 minutes for MRI examination. The specific time to produce the results is related to the size of the hospital and the number of people doing the examination, because the doctor has to read the film after doing the examination, and the corresponding report sheet has to come out together with the film, which takes time to process. Routinely, the results of X-ray examinations can be produced in about half an hour, while CT examinations can be produced in about two hours, and the results of MRI examinations can take half a day or a day or so. However, if the hospital is particularly large, like Beijing and Shanghai, the whole time may be longer, and some MRI results can take about a week.
