KNEE MRI SCAN: Are you suffering from knee pain and are in the process of having a Knee MRI?
Knee MRI Scan is organised by an orthopaedic surgeon to understand the inside of your knee so that they will be able to plan your treatment. Knee MRI Scan is a harmless test which can help your specialist to identify the cause of knee pain. A well reported MRI Scan of the knee can lead to better health outcomes by taking away the need for keyhole operation for diagnostic purposes. Examination of your knee by a GP, Physiotherapist or a specialist is still a good starting tool for diagnosis of knee pain. If the diagnosis of knee pain is clear, your specialist may not arrange an MRI scan.

The radiographer will ask you to remove all such items. MRI Scanning can cause issues in the following scenarios

It is not uncommon for a specialist to ask for an MRI scan of your knee to understand if your unexplained pain is coming from the parts of the knee that are un-replaced.
- Tibial Tubercle Transfer: This operation leaves you with some screws in your shin bone. MRI scan of the knee may cause some artefacts, but these are away from the knee and do not cause diagnostic issues.
- Osteochondral cartilage operation: This operation should not cause any issues with image artefact.

The radiographer will explain the procedure to you before you have your scan. You will be asked to change into something comfortable.

You will be asked to come into the MRI scanning room, once the safety check is complete. Your position will depend on your scan type (lying or standing position). 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. The radiographer will advise you with regards to the length of the sequence during which you would be asked to remain static as the movement will cause image artefacts which might reduce the accuracy of the results.
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.
