contrast arthrograph

contrast arthrography

- the radiographic exam of the soft tissue structures of joints after the injection of contrast media contrast arthrography
Water-soluble iodinated contrast material and air are used to? visualize the joints
Which joints is contrast arthrography preformed on? knee, wrist, hip, shoulder, and TMJ
What type of joints are the knee, wrist, hip and shoulder? diarthrodial joint
What is the most frequent site of contrast arthrography? the knee
What are the soft tissue structures of concern when doing a contrast arthrography? ligaments, torn meniscus, articular cartilage, bursae, Baker's cysts and complete and incomplete rotator cuff tears
What connects bone to bone? ligaments
Why type of needles are typicaly used in contrast arthrography of the hip and shoulder? spinal needles
What is the process for joint effusion? joint effusion before contrast administration
How is contrast administered? under fluoroscopy
What does a stress device do? allows for better distribution of the contrast material around the meniscus
What method is used with knee arthrography? horizontal ray method
What contrast materials are used for knee arthrography? water-soluble idoinated and air
To demonstrate the medial meniscus, how is the patient positioned? semiprone with medial meniscus up
What improves outlining of the knee joint structures? horizontal beam position and small amts of each of the two contrast agents
What is the result of excess heavy iodinated solutions ? they drain into the dependent part of the joint, leaving a thin opaque coating on the gas-enevloped uppermost part being imaged
What is the common puncture site for hip arthrography? 3/4" distal to the inguinal crease and 3/4" lateral to palpated femoral pulse
Shoulder arthrographyis used to evaluate what conditions? partial or complete tears in rotator cuff or glenoid labrum persistent pain or weakness frozen shoulder
- small, oval fibrocartilage located between mandibular condyle and mandibular fossa articular disk
What has replaced TMJ arthrography? CT and MRI
Why is fluoroscopy used in examining TMJ? to observe and image mandibular motion
How is the mouth positioned in projections of TMJ? with pt mouth closed, partially open and fully open
