Sažetak
Learning objectives: Learning objective is to present the easiest access to the glenohumeral joint under the ultrasound guidance, for Magnetic Resonance (MR) arthrography which can be also used for steroide injections. Background: MR arthrography still remains the gold standard in identifying labral lesions as on plain MR contrast resolution is scarse. In the past contrast media were injected under the fluoroscopic guidance, exposing patients and staff to the radiation. Imaging findings or procedure details: Patient is positioned on the opposite flank with the hand holding the opposite shoulder. Under ultrasound guidance 5 mL of Lidocain is injected mostly in the subcutaneous tissue (picture 1). After a minute (when patient loses the feeling on the puncture place) posterior recess of the glenohumeral (GH) joint is visualized. Usually the probe is placed 15 mm medially and 15 mm caudally to the acromion. Probe is placed in the tranverse plane, which worsens the visualization of the needle, but facilitates the view of GH joint which usually is located on 3-5 cm below the surface (picture 2). 12 mL of mixture of 5 mL Lidocain, 0.5 mL Dotarem, 5 mL saline solution and 10 mL of iodinated contrast is injected intraarticulary when the tip of the needle is visualized in the humeral periosteum. T1 fat saturated sequences in all three planes are then acquired. We have used the manufacturer shoulder coil on 1.5 MR units (Avanto, Siemens AG Medical Solutions, Erlangen, Germany and Ingenia, Koninklijke Philips N.V., Amsterdam, The Netherlands) (picture 3). Conclusion: Injection under the ultrasound guidance is an easy and quick way of reaching the glenohumeral joint, without radiation exposure which can be used for MR arthrography and steroid injections. We present technical details of procedure and pictorial essay of lesions found in series of 23 patients done at the Diagnostic and Interventional Radiology Department at the University Hospital Dubrava, University of Zagreb, School of Medicine.
