MR arthrography (direct) - Frequently asked questions

When does direct arthrography make sense?

Performing a direct MR arthrography only makes sense in certain cases. These include the examination of the shoulder in the case of a SLAP lesion (injury to the start of the long biceps tendon) or in the case of existing multidirectional instability, the case of a discus lesion of the wrist and of a femuro-acetabular impingement (FAI) of the hip.

Examinations of other joints are the exception.

What must be borne in mind when performing an MR arthrography?

Medicines which thin the blood (ASS, Aspirin, Heparin) must be discontinued before the examination.

MR arthrography may only be performed on patients undergoing marcumar therapy after they have switched to heparin or have a Quick value of >50%.

How long does direct MR arthrography take?

The injection into the joint must take place under sterile conditions. Consequently c. 20-30 minutes must be scheduled for the injection. The subsequent MRI takes roughly another 30 minutes, which means that a total of 1.5 hours should be scheduled for the examination.

What must be borne in mind for MR arthrography?

The injection into the joint causes a slight feeling of pressure in the joint capsule which can last for c. 2 hours after the injection.
No active sporting activities should be performed for c. 24 hours after the injection.

Who conducts the examinations?

The injection into the joint in our practice is currently only performed by Dr. Thomas Winter. This ensures maximum safety and familiarity with the procedure.

The MRI examinations are appraised by specially trained doctors at Sonnenstrasse 17 and Ridlerstrasse 37.
