Magnetic Resonance arthrography is considered the gold standard imaging technique for the study of shoulder instability and tendon tears.We describe an image artefact, characterized by decreased signal intensity of the paramagnetic gadolinium chelate contrast agent during a shoulder Magnetic Resonance arthrography, attributable to an incorrect concentration which does not cause evident capsular...

INTRODUCTION The aim of our study was to compare US, conventional MRI and MR arthrography findings in patients with anterior shoulder instability and with a clinical diagnosis of labral capsular ligamentous complex lesion. At the same time we evaluated the accuracy of MR arthrography in the diagnosis of this lesion. METHODS After approval of the local Ethics Committee, our department's Trauma...

BACKGROUND Knee pain is a common problem in the general population. In order to determine the extent of the injury and the appropriate treatment, MRI provides the most accurate imaging method. This may be done through conventional MRI techniques or by injecting a contrast material (MR arthrography). OBJECTIVES The purpose of this study was to compare the diagnostic value of these two methods....

OBJECTIVE The purpose of this study was to evaluate the diagnostic accuracy of 3-T MRI versus 3-T MR arthrography for assessing labral abnormalities in the shoulder using arthroscopy as the gold standard. SUBJECTS AND METHODS Forty-two patients (28 men, 14 women; mean age, 33 years) underwent MR arthrography and conventional MRI of the same shoulder. Two patients underwent bilateral shoulder ...

BACKGROUND Various pediatric conditions often necessitate a morphologic examination of the hip joint in infancy or childhood, and multiple imaging options have been employed to achieve this goal. Arthrography is one such modality. Different types of contrast media have been utilized and include pharmacologic contrast agents, air, and carbon dioxide. There are scattered reports of complications ...

OBJECTIVE The purpose of this study was to anatomically confirm that anterior shoulder injection could result in penetration of the anterior stabilizing structures of the glenohumeral joint and to advocate the use of a tailored approach to MR arthrography based on presenting symptoms. CONCLUSION A tailored approach to MR arthrography may be a useful way to isolate expected pathology in the sh...

Magnetic resonance arthrography (MRA) is commonly used to detect labral tears of the hip. Complications of MRA are unusual and include minor reactions such as chemical synovitis and urticaria. This paper presents a rapidly progressive chondrolysis of the hip in a young patient after arthrography. The patient had suffered from acute septic arthritis and was treated by emergent arthroscopic surge...

The ability of nuclear magnetic resonance (NMR) tomographic imaging to show a change in proton spin-lattice relaxation time (T1 value) in the joints of patients with rheumatoid arthritis before and after treatment with intra-articular steroid has been assessed. Six patients with seropositive rheumatoid arthritis and clinical evidence of a popliteal cyst were examined by both NMR tomography and ...
