Doppler Ultrasound (Arterial Resistance Explained)

Let's explore resistance, arterial resistance that is! Join me as we discover what arterial resistance is, why it matters and how to calculate the resistance of a vessel (resistive index) on Ultrasound. Learn techniques for distinguishing between high resistance and low resistance waveforms on Spectral Doppler Ultrasound. Covers topics found on the video: Doppler Ultrasound (Arteries vs Veins); this video is just broken down into a bite-sized piece for you. Arterial resistance is a topic crucial to Vascular Ultrasound, and is used to assess the resistance level of vessels supplying organs that are commonly evaluated in General Ultrasound. If you perform Ultrasound exams, it's vital to understand this central concept...

Hi! I'm Michelle Macauley. Welcome to my channel- Sonography Minutes!
I've been a Sonographer for over 15 years and I also teach Ultrasound at the College level, where I've built a Breast Ultrasound course for both Mammographers and Sonographers.
My specialty is Breast Ultrasound, though I have experience in multiple types of Ultrasound.
I hold ARDMS certifications in Breast, Abdomen and OBGYN, and I'm also an RVT (Registered Vascular Technologist).
Join me as I cover all things Ultrasound!
