The combination of unique texture and sweet, tart flavor has made grapes an ever popular between-meal snack as well as a refreshing addition to both fruit and vegetable salads. Grapes are small round or oval berries that feature semi-translucent flesh encased by a smooth skin.
A venogram is a test that lets your healthcare provider see the veins in your body, especially in your legs. A special dye is injected that can be seen on an X-ray. The dye lets your healthcare provider see your veins and how healthy they are. A venogram is used to diagnose deep vein thrombosis (DVT) or other abnormalities of your veins.
A venous ultrasound study is also performed to: 1  determine the cause of long-standing leg swelling. 2  aid in guiding placement of a needle or catheter into a vein. 3  map out the veins in the leg or arm so that pieces of vein may be removed and used to bypass a narrowed or blocked blood vessel.
