A specialised knee coil is placed around your knee. Once the position is confirmed, the radiographer will take predetermined sequence of the image. The scanner at the Bromsgrove private clinic is open and allows you to communicate with the radiographer at all times.

If you are having an MRI scan of the knee in a standing position, the radiographer will operate the automatic and technologically significantly advanced bed mechanism to allow the scan be carried out in a standing position. A few sequences are done while you are standing. The radiographer will print your MRI scan images on a CD which will be handed over to you if your specialist has requested this. A copy of the disk also goes to the expert radiologist will report on your scan.
