Vascular Ultrasound T2 Surgical and Interventional Ultrasound YR 2014 FD 2014 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-176762-0 LK accesssurgery.mhmedical.com/content.aspx?aid=57916892 RD 2024/03/28 AB Vascular anatomy and physiology lend themselves readily to the modality of ultrasound. Ultrasound’s ability to assess velocity of moving fluid allows for real-time evaluation of the speed and direction with which blood is flowing through a vessel. This provides for a dynamic assessment of the vascular tree. In addition the ability of ultrasound to measure distances allows it to be a very effective method for screening for dilated blood vessels. The ease of use, relatively low cost of the devices, and speed of the tests allow ultrasound to be the lowest-cost method next to physical examination to assess the vascular beds. These unique properties of ultrasound allow for the accredited Vascular Laboratories, with the appropriately credentialed and trained physician, the technologist, and a program of continuous quality assurance, to obtain results that are comparable to much more expensive imaging techniques.
