A magnet surrounds the tube. You lie on a table that slides all the way into the tube. In a short-bore system, you are not totally inside the MRI machine. Only the part of your body that's being scanned is inside. The rest of your body is outside the machine. An open MRI is ...

The human body is mostly water. Water molecules (H2O) contain hydrogen nuclei (protons), which become aligned in a magnetic field. An MRI scanner applies a very strong magnetic field (about 0.2 to 3 teslas, or roughly a thousand times the strength of a typical fridge magnet), which aligns...
An MRI is similar to acomputerized tomography(CT) scanner in that it produces cross-sectional images of the body. Looking at images of the body in cross section can be compared to looking at the inside of a loaf of bread by slicing it. Unlike aCT scan, MRI does not use X-rays. Inste...
An MRI is done with the use of a very big magnet and radio waves. It's commonly used for: Abscesses Infections Cancer of the brain, spinal cord, breast, prostate, uterus and in some cases, liver A CT scan, MRI or ultrasound can use two-dimensional (2D) or three-dimensional (3D) ...
What is an MRI? What is angular momentum? What is inversion in meteorology? What is nuclear disintegration? What do Rossby waves do? What are tidal current turbines? What is a superconductor? What is resistivity in geophysics? What are Polar Easterlies?
The MRI machine uses a powerful magnet. Do not enter the MRI room with anything metal. Metal can cause serious injury from the magnet. Tell the healthcare provider if you have any metal in or on your body. An arteriography is used to take x-rays of your arteries to look for blood ...
As the nurse, you can make a big difference to patients who have to undergo an MRI or PET scan. The equipment is daunting, and the procedures themselves can involve some discomfort, so the patient will need thorough preparation for the experience. How...
