MRI uses short bursts of radio, at frequencies of a few tens to a few hundreds of Megahertz.
Exactly the same radiation that comes out of an ordinary TV transmitter, but in short bleeps,
and without any sound or picture modulation on it.
A gamma ray is an electromagnetic wave. It has the highest frequency (and energy) as well as the shortest wavelength on any wave on the electromagnetic spectrum.
A sunflower is a common example of a flower that consists of a cluster of tightly packed ray flowers around the edge and disk flowers in the center.
It means that a specific area on the left side of the brain is of concern and further investigation is needed through a magnetic resonance imaging (MRI) scan to better understand any abnormalities or potential issues in that area. An MRI can provide detailed images of the brain to help diagnose any potential conditions or concerns.
Becuase the only thing an MRI doese is check for things that shouldn't be there in your brain. It's not a treatment option. That aside, most people don't have things that need to be scanned for or they just can't afford them, as sad as it is.
An arthrogram is a medical imaging technique where a contrast dye is injected into a joint, usually the shoulder, knee, or hip, before performing an X-ray, MRI, or CT scan. This helps to better visualize the joint and its surrounding structures, aiding in the diagnosis of certain conditions like tears, inflammation, or damage.
