Have you recently had an MRI scan? You may have heard that when you have an MRI, a special medicine is sometimes injected into a vein to help clarify the images on the scan. It's normal to feel a little scared and curious when you hear this. Today we're talking about a 'contrast agent', a special medicine that is given to help clarify the images during scans. Its name is Gadobutrol.
Simply put, what is Gadobutrol?
Imagine, you're looking at a black and white picture, but some parts of it are not clearly visible. How much clearer would it be if someone came and colored those invisible parts beautifully? That's what this drug called Gadobutrol does.
This is a special liquid that helps to see more clearly and brightly if there are abnormalities in the organs, blood vessels, and tissues inside our body during an MRI (Magnetic Resonance Imaging) or MRA (Magnetic Resonance Angiography) scan. This is a great help for the doctor to find out exactly what is happening inside your body. You can see this in the market under the name `(Gadavist)`.
