Episode 050 -- Stroke Imaging with Sound with Dr. Aaron Stayman

My first day in the hospital was filled with MRIs and CT Scans. Okay that a little exaggeration, there was only one MRI and 2 CT scans. Still, they were unpleasant. Plus, they're expensive, and you have to go elsewhere in the hospital.

It turns out there's another option, that many neurologists don't even know about. It's called Transcranial Doppler Ultrasound, and it gives the medical team information the other scans don't. Plus, it involves no radiation or special rooms.

It doesn't replace the other scans altogether, but give the doctors another tool for treating stroke patients.

This week, I talk with Dr, Aaron Stayman from Swedish Medical Center. Dr. Stayman is an advocate for and expert in Transcranial Doppler Ultrasound. This week, we learn about his background, talk about aphasia, and spent the bulk of our time talking about Transcranial Doppler Ultrasound. We explore what it is, how it works, and how it benefits patients.

Aaron cites 5  benefits of Transcranial Doppler Ultrasound

  1. It's cheaper
  2. There's no radiation
  3. It's portable
  4. It's repeatable
  5. There are no issues related to magnets


Here's a short look at what the doctor sees in a scan:



Dr. Aaron Stayman attended medical school at Tufts University in Boston, MA.  He completed an internship in internal medicine and a neurology residency at Vanderbilt Medical Center in Nashville, TN.  During his vascular neurology fellowship at Emory University in Atlanta, GA, he received specific training in the performance and interpretation of carotid and transcranial ultrasound.  He is currently a neurohospitalist at Swedish Medical Center and Medical Director of the Swedish Cerebrovascular Ultrasound Laboratory.

Continuing Medical education in Transcranial Doppler Ultrasound

Are you a medical professional who wants to learn more? Swedish and Pacific Vascular have a course coming up in September of 2019.



Jointly provided by Pacific Vascular and Swedish CME, in collaboration with Swedish Neuroscience Institute, this program has a nationally recognized faculty with diverse areas of specialization, a comprehensive and in-depth curriculum and hands-on sessions with patient models utilizing a variety of TCD and TCD Imaging systems.  The three-day course is held at a state-of-the-art educational facility conveniently located at the acclaimed Swedish/Cherry Hill Hospital campus in Seattle WA.

Hack of the Week


Today's Tip comes from Twitter User @Nursery1994, AKA Abigail Johnson

Earlier this week, I was thinking about making pasta. My GF rightly pointed out that I will need to figure out how to drain the hot water from the pasta with one hand without spilling it and the water all over myself and the kitchen floor. Before we completed this problem solving, she went ahead and made it because she's awesome like that.

Later on, I stumbled across a strategy on Twitter. Put a colander or wire strainer that you can lift with one hand. Fill the pot with water, and add the pasta to the strainer before cooking it. Then boil or whatever, and when it's done, just lift out the strainer with the pasta and leave the water behind.

You know, basically the way the make French fries at McDonalds.


Facebook and Strokecast


Strokecast also has a presence on Facebook. Just search for Strokecast the next time you're on Facebook for more videos where I share stroke related things that just happen to be on my mind. Sometimes they are well thought out; sometimes they are still thoughts in progress, but it's fun stuff regardless. Click here to head over to Facebook and check it out.
