A vascular technologist is a highly-skilled professional who uses a transducer to image vessels within the body. The transducer works like a loudspeaker and microphone because it can transmit sound and receive sound. The transducer detects sound waves as they bounce off the internal structures. Different structures in the body reflect these sound waves differently and are used to make an image on a screen.
Vascular technologists evaluate the arteries and veins in nearly any part of the body. The images they obtain help to aid the physician in a medical diagnosis. Three main exams are performed by the vascular technologist:
- Lower extremity venous - performed if a clot in the vein (deep venous thrombosis or DVT) is suspected.
- Lower extremity arterial - performed in patients to check for peripheral vascular disease (PVD).
- Carotid arteries - performed to check for blockages that may lead to a stroke.
