Performing more than 12,000 vascular studies a year, Guthrie offers studies of the carotid arteries to determine if a blockage is present. Using Duplex Scanning, Guthrie vascular technologists can view the arteries in the extremities and study the pulse waveform recordings with Doppler pressure. To detect deep vein thrombosis, an examination is performed using Duplex imaging with color flow Doppler. All of the tests are noninvasive, with no discomfort. Guthrie offers seven vascular study locations including Big Flats, Corning, Ithaca and Owego, N.Y. and Sayre, Towanda and Wellsboro, Pa.
