What Student Need to Know about Venography – Blood Flow Examination of Veins In Radio Diagnosis.

Venography is an invasive X-Ray imaging test that takes pictures of a contrast dye flowing through the veins of any part of the body (frequently the legs), allowing the radiologist to determine the location and type of any vein abnormality, (like an abnormal anatomy, blockages/clots, enlargements, malformations) or to ensure that catheters are placed correctly for treatments such as an infusion of a drug to dissolve a blood clot. Although venography has been the “gold standard” for diagnosis of DVT, other diagnostic studies are accurate when performed by a skilled technologist and, in most patients, may replace the need for routine contrast venography. Venography is moderately uncomfortable, requires the injection of a contrast material that may cause allergic reaction or renal injury, and may result in phlebitis in approximately 5% of patients. How does the procedure work? X-rays are a form of radiation like light or radio waves. X-rays pass through most objects, including the body. Once it is caref
