Indications for an MRT of the hand
An MRI examination of the hand or wrist serves to precisely distinguish between various diseases and injuries. Through an exact depiction of soft tissue structures (joints, ligaments, muscle tendons), the finest tears, traumas and signs of wear and tear can be shown. MRI imaging of the hand is therefore often used following X-ray diagnostics when no causes of a patient’s symptoms could be found in the X-ray images.
Other indications for an MRI of the hand are:
- Representation of inflammation
- Representation of tumors
- Diagnostics of rheumatoid arthritis
With the help of the MRI it is possible to confirm or exclude the suspicion of a rheumatic disease of the joints or to assess its course. In particular, the MRI is used for early diagnosis, since x-rays usually do not reveal pathological findings at an early stage. In contrast to X-rays, MRI can detect bony changes at an earlier stage and show inflammation in the joint or tendons.
In the case of an MRI of the hand for rheumatic conditions, contrast medium is usually required for the reasons mentioned above. A ganglion (synonym: ganglion) often manifests itself as a node in the area of the joint surface. This can occur in the area of the extensor as well as the flexor side.
These are cysts filled with synovial fluid, which occur through gaps or tears in the joint capsule. The patient often complains of pain in the wrist, which occurs mainly during strong stretching or bending movements. Usually, a ganglion can already be visualized in a normal MRI examination.
It is an accumulation of fluid in the area of the body surface, which appears white in T2-weighted images. Direct injection of contrast medium into the joint capsule (MR-arthrography) can clarify the connection to the actual joint. The discus of the wrist (Discus triangularis, TFCC) represents a triangular joint connection between ulna, radius and the carpal bones. It can be damaged and cause pain, especially when the wrist is rotated or when the wrist is injured.An MRI examination can diagnose the finest injuries in the area of the joint surfaces. Furthermore, conclusions can be drawn about the origin and causes of these injuries.
