Exam Requirements: Vascular Ultrasound (Revised 10-13-2023)

Revision History



The Vascular module includes the following submodules:

  • Peripheral Arterial

  • Peripheral Venous

  • Cerebrovascular

  • Liver Vasculature

  • Renal Vasculature

  • Aorta

Sites must apply for all submodules performed. If only one submodule is performed, two examinations are required for that submodule. If two or more submodules are performed, one examination from each submodule performed is required. 


Complete documentation/survey means a series of several images throughout the entire organ in two planes. For example, from one side of the organ to the other in the longitudinal plane and from superior to inferior in the transverse plane. 


Anatomy should be intentionally imaged in an organized fashion and correctly labeled for clarity.
