What is knee arthrography?What is arthrography? Arthrography is a type of imaging test used to look at a joint, such as the shoulder, knee, or hip. It may be done if standard X-rays do not show the needed details of the joint structure and function.
Where is contrast media instilled during a myelogram?The contrast medium is injected into the subarachnoid space by lumbar puncture.
Which of the following tomographic techniques would be most suitable for a study of the entire mandible?CT is the current diagnostic tool of choice for the radiographic evaluation and diagnosis of mandible fractures. A panoramic tomographic view (Panorex view) [6, 7, 4] shows the entire mandible in one plane.
