Radiologist – Career Connections – WVIZ ideastream


(woman)
A radiologist is somebody
who interprets images from different parts
of the patient’s body. We can do X-rays, CT scans, we can do MRIs,
we can do ultrasound, based on what disease you’re trying to see
if the patient has. My name is Deborah Kwon, and my area of expertise
is cardiology, or the heart. Our focus is acquiring images that assess the heart function,
the valve function, how well the ventricles
are squeezing, and seeing if there’s diseases
of the muscle tissue itself. The heart is a fascinating
organ, in that it is a pump. Our arteries
can be thought of as pipes. The physics
that are applied to flow through a pipe
can be applied to the heart. Every day, for me,
is a little different. I have the luxury
of being able to read all different types
of modalities within the heart. On a Monday, I read ultrasound of the heart,
or echocardiograms. On Tuesday,
I read CT scans. On Wednesday,
I see clinic patients. On Thursdays, I read MRI. Some material there. And Friday is usually
a research day for me. I’m very involved
in research projects as well. For reading scans,
we’re dependent on the computer. These images are digitalized
and sent to the computer, and we interpret them. This is an echocardiogram. You can see the beating heart. We apply color Doppler
that’s like the weather Doppler on The Weather Channel. Instead of wind,
we’re studying the velocity and direction of blood flow. Here you can see
there’s a leaky mitral valve and a leaky aortic valve. This blue-and-yellow color
coming backwards is blood flow flowing this way, which is the opposite way
of how blood should be flowing. On a daily basis,
I’m constantly using math. We have to calculate
gradients and flow. So we’re using that
on a daily basis. My favorite part of the job is seeing images
that are fascinating– that you can see
a beating heart. The thing that I think is
so fascinating about cardiology is a lot of the diseases
are curable, whether it’s through surgery, or very treatable
through medications, and you can actually see
patients getting better and actively prolong
people’s lives. Funding to purchase and make
