Thanks Megaspaz!) Like the left turn this is another hand signal that you should know if you have your license. Unlike the left hand turn this one is a little more tricky to figure out if you aren't familiar with it so don't expect your average car driver to know what this means.
A Single Photon Emission Computed Tomography (SPECT) scan is a type of nuclear imaging test that shows how blood flows to tissues and organs. A SPECT scan integrates two technologies to view your body: computed tomography (CT) and a radioactive material (tracer). The tracer is what allows doctors to see how blood flows to tissues and organs.
The pictures will help your doctor see if your heart is getting enough blood or if blood flow is reduced because of narrowed arteries. A SPECT scan can be used to examine blood flow in your heart at rest and during exercise (called a nuclear stress test). If you canât exercise, youâll get a medicine to increase the blood flow in your heart as if you were exercising (called a chemical or pharmacologic stress).
