Technique of preparing X-ray images of a vein injected with a radiopaque contrast medium.
X-ray examination of the veins after injection of dye that absorbs the x-rays.
A radiographic procedure that shows the internal structures of veins after the patient receives an injection of contrast medium.
X-ray examination to show up the course of veins in a particular region of the body. A radio-opaque contrast medium is injected slowly into a vein and X-ray photographs (venograms) taken as the compound is carried toward the heart. Damage, obstruction, or abnormal communication with other vessels will be seen where the medium does not fill the vein properly or apparently leaks from it.
The study of the veins, particularly by means of X-rays after the veins have been injected with a radio-opaque substance.
A radiographic procedure to visualize veins filled with a contrast medium; most commonly used to detect thrombophlebitis.
