Disease relevance of Arthrography

• Five cases of an antefemoral synovial cyst in rheumatoid arthritis were confirmed by arthrography [1].
• PATIENTS AND METHODS: Sixteen patients with adhesive capsulitis of the shoulder were treated with therapeutic capsular distention by using intra-articular injection of a 30-mL mixture of lidocaine, corticosteroid, and contrast media immediately following diagnostic arthrography [2].
• As lack of such attachment is a relative indication for surgery, we studied the feasibility of using coronal computed tomography (CT) after double contrast arthrography to demonstrate attachment in four patients with osteochondritis dissecans seen on radiographs [3].
• Indications for CT arthrography are recurrent dislocation, multidirectional instability, severe rheumatoid arthritis and other arthritides, complex shoulder deformities and suspected loose bodies [4].
• Radionuclide arthrography should be considered in patients with unexplained calf pain or pain behind the knee, especially with a history of previous internal knee derangement, or rheumatoid arthritis in whom ruptured cysts can closely mimic acute thrombophlebitis [5].

High impact information on Arthrography

• CONCLUSION: MR arthrography demonstrated a triad of abnormal head-neck morphology, anterosuperior cartilage abnormality, and anterosuperior labral abnormality in 37 of 42 patients with cam-type femoroacetabular impingement [6].
• T1-weighted spin-echo MR imaging and MR arthrography in standard imaging planes and a coronal oblique plane were performed in eight other elbow specimens [7].
• MATERIALS AND METHODS: Thirty-two patients with chronic ankle pain prospectively underwent gadolinium-enhanced MR arthrography of the tibiotalar joint [8].
• MR arthrography of the glenohumeral joint: two concentrations of gadoteridol versus Ringer solution as the intraarticular contrast material [9].
• MR arthrography was performed in four specimens (eight joints), after injection of gadopentetate dimeglumine [10].

Chemical compound and disease context of Arthrography

• Thickness of capsule and synovium of the axillary recess greater than 3 mm is a practical MR criterion for diagnosing adhesive capsulitis when measured on oblique coronal T2-weighted MR arthrography images without fat suppression [11].
• CONCLUSION: Glenohumeral distension arthrography with steroid injection followed by physical therapy is effective in expediting the spontaneously favorable outcome of adhesive capsulitis and also allows to confirm the diagnosis [12].

Biological context of Arthrography

• Aspiration arthrography costs approximately 20% as much as complementary technetium sulfur colloid-indium-111 granulocyte scans, the most accurate nuclear medicine study used to evaluate potentially infected hip prostheses [13].

Anatomical context of Arthrography

• MATERIALS AND METHODS: In 121 patients with diagnoses proved surgically, the labrum, glenohumeral ligaments, and capsular insertion types were assessed prospectively with gadolinium-enhanced MR arthrography [14].
• Horizontal component of partial-thickness tears of rotator cuff: imaging characteristics and comparison of ABER view with oblique coronal view at MR arthrography initial results [15].
• Collateral ligaments of the elbow: conventional MR imaging and MR arthrography with coronal oblique plane and elbow flexion [16].
• The technique was not helpful in the following conditions: early soft-tissue changes of rheumatoid arthritis; detection of minimal skeletal trauma; arthrography of the knee; evaluation of any portion of the vertebral column; evaluation of submandibular neck masses; or assessment of abdominal films for visceral structures [17].
• CONCLUSION: The application of external heat increases uptake of intravenously administered Gd contrast into the knee joint, and may help to optimize indirect MR arthrography at a relatively low cost [18].

Associations of Arthrography with chemical compounds

• Subsequently, gadolinium-enhanced arthrography was performed in three specimens followed by T1-weighted spin-echo and SPGR MR imaging [19].
• Knee arthrography: a comparison of iohexol, ioxaglate sodium meglumine, and metrizoate [20].
• Knee arthrography: comparison of iotrolan and ioxaglate sodium meglumine [21].
• This prospective study compares immediate and delayed patient discomfort in 177 patients following shoulder arthrography using intraarticular combinations of metrizamide, meglumine/sodium diatrizoate, meglumine diatrizoate, lidocaine, epinephrine, and air [22].
• RESULTS: Saline-enhanced MR arthrography was positive in 24 of 26 individuals with UCL tear confirmed at the time of surgery [23].

Gene context of Arthrography

• The authors have performed in these five cases an arthrography of T11 and T12 CV joints [24].
• Shoulder arthrography in rheumatoid arthritis [25].
• Arthrography of the wrist was performed on 300 consecutive patients by injecting contrast material separately into the radiocarpal (RCJ), midcarpal (MCJ), and distal radioulnar (DRUJ) joints [26].
• CONCLUSION: Nuclear arthrography is a sensitive technique for detection of loosening of prostheses, offering added value over radiographic arthrography and bone scanning alone, especially for evaluation of the femoral component [27].
• The significance of the diagnostic agreement between the clinicians and arthrography was evaluated with a Kappa Statistical Test, which showed good reliability [28].

Analytical, diagnostic and therapeutic context of Arthrography

• The arthrographic effect may provide a more convenient alternative to intraarticular injection of gadopentetate dimeglumine for MR arthrography [29].
• METHODS: Five parameters were assessed in 40 patients: clinical assessment, high-resolution magnetic resonance imaging, magnetic resonance imaging with gadolinium arthrography, intra-articular bupivacaine injection, and arthroscopy [30].
• RESULTS: Performing indirect MR arthrography of the unexercised shoulder leads to a diagnostically efficient enhancement of joint fluid (120% at 4 minutes and 145% at 8 minutes after intravenous injection of gadodiamide) [31].
• Characterization of anatomic communications among the antebrachiocarpal, middle carpal, and carpometacarpal joints in cattle, using intra-articular latex, positive-contrast arthrography, and fluoroscopy [32].
• Communication between 2 joints was determined by presence of latex and contrast material in a joint adjacent to the injected joint by examining frozen sections and use of positive-contrast arthrography [33].
