Quiz: Test Your Knowledge of Stress and Anxiety. Stress and anxiety are the same thing. You answered: Correct Answer: Stress is your response to a change in your environment, be it positive or negative.

Anxiety is an emotion thatâs characterized by a feeling of apprehension, nervousness, or fear. The causes of stress are essentially the same for everyone.
Alternate methods of direct arthrography examinations may also use magnetic resonance imaging (MRI) or computed tomography (CT) following contrast material injection into the joint. An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Direct arthrography is particularly effective for detecting disease of the structures within the joints such as ligaments, tendons and cartilage. 2  This is particularly true for the shoulder in the setting of shoulder dislocation and in the hip, wrist and elbow.
MRI stands for magnetic resonance imaging; it basically uses powerful magnets and radio waves to create detailed images of the interior of your body. It can be done with or without contrast. Contrast is a type of dye that is injected intravenously either right before, or during the procedure. Certain abnormalities, such as tumors, will absorb the dye and show up very clearly on the MRI with contrast. Your doctor will determine whether you need an MRI with contrast or without, and may order both tests. An MRI scan is different than a regular x-ray or a CT scan, which both use ionizing radiation to create images. MRI scans generally produce clearer images with much more detail than an x-ray or CT scan.
