VAS 230 – Essentials of Vascular Sonography (Non-invasive)

 

Course Description

This course is designed as an introduction into the field of vascular sonography. The general practitioner will be required to perform venous examinations of the lower extremity, arterial studies of the neck, and some Doppler studies within the abdomen. For these areas much greater depth will be reached. The field of vascular sonography is much wider and encompassing than these three areas. The broader field of vascular sonography will be introduced but not studied at length or in depth. Emphasis is on the functional workings and settings associated with Doppler signals and waveforms. Topics include: machine/image settings for Doppler imaging; venous imaging of the lower extremities; arterial imaging of the neck; and vascular imaging of the abdomen, including aorta and its primary branches, vena cava, portal and hepatic veins, and renal arteries and veins.
