arthrography

Shoulder arthrography can be used to study tears of the rotator cuff.

In these circumstances, magnetic resonance arthrography can improve the differentiation.

This technique has replaced previous arthrography, which involved injecting contrast medium into the joint space.

Arthrography: a dye is injected into the wrist joint.

The lesion is best identified on MR arthrography.

Hydrodilatation or distension arthrography is controversial.

Current practice is single contrast arthrography usually coupled with CT or MR imaging.

Ultrasonography, arthrography and MRI can be used to detect rotator cuff muscle pathology.

Double-contrast arthrography involves injecting contrast dye into the shoulder joint to detect leakage out of the injured rotator cuff.

Like CT arthrography, MR with gadolinium may be used to detect intra-articular bodies that have not yet calcified.

Hydrodilatation or hydraulic arthrographic capsular distension or distension arthrography is a medical treatment for adhesive capsulitis of shoulder.

Arthrography and venography using imaging dyes allow for the detection of popliteal cysts and the exclusion of thrombotic lesions but are invasive procedures.

Stetson et al. reported an overall sensitivity of 91% (9% false negative rate) and concluded that magnetic resonance arthrography was a very reliable test in the detection of partial-thickness rotator cuff tears.

MR arthrography is most often used in evaluation of the hip and acetabular labrum, of the shoulder rotator cuff and glenoid labrum, and less often in the wrist.

In this condition, imaging modalities often indicated include the use of Doppler and non-Doppler ultrasound, arthrography, venography magnetic resonance imaging (MRI) and computerised axial tomography (CAT scan).

For pneumoarthrography, a gaseous medium has been used, for opaque arthrography a water-soluble iodinated medium is used, and a combination of both has been used in double-contrast arthrography.

However, the routine use of magnetic resonance arthrography is not advised since it involves entering the joint with a needle with possible risk of infection and the test is reserved for those cases in which the diagnosis remains unclear.

Increasingly utilized in the last ten years, Magnetic Resonance Arthrography and Computed tomography arthrography (CT) combines a standard arthrogram with Magnetic Resonance Imaging or CT scanning.

The conventional invasive arthrography is now-a-days being replaced by the non-invasive MRI and US and is used as an imaging reserve for patients who are contraindicated for MRI, for example pacemaker-carriers with an unclear and unsure ultrasonography.

In comparison to a checking MR Arthrography Strobel K. et al. has arrived at the conclusion that through THI it is possible to achieve a generally improved visibility of joint and tendon surfaces, especially superior for subscapularis tendon abnormalities.
