Vascular Ultrasound

Vascular ultrasound is used to examine the arteries and veins of the body for areas of blockage, narrowing, clot formation, trauma and congenital malformation. The exam is painless. The time required to complete the exam is variable depending upon the size and complexity of the region that needs to be examined. The exam produces a color image of the blood vessels  that provides the technologist with information about the speed and direction of blood flow. Regions of narrowing can be seen directly that can be evaluated for severity. 

The most commonly examined regions include:

• Arteries of the neck for degenerative changes.

• Arteries of the arms for narrowing, blockage, trauma.

• Arteries of the legs for degenerative changes.

• Veins of the arms and legs for clots ("thombosis")
