Functional MRI In addition to structural imaging, MRI can also be used to visualize functional activity in the brain. Functional MRI, or fMRI, measures changes in blood flow to different parts of the brain. It is used to observe brain structures and to determine which parts of the brain are...
The MRI is basically a tube-shaped magnet. While you're inside the machine, protons from water in your body get pulled into the magnetic field around you and start to line up. The machine also sends out radio waves that cause these protons to spin. When the waves are turned off, the ...

What Are the Risks of MRI? MRI is a very safe procedure. The strong magnetic field itself does not hurt people, unless they have certain types of metal implanted in their body. The magnetic field can cause certain types of metal to move, which could potentially cause an injury. ...
Magnetic resonance imaging (MRI):The non-invasive imaging technology discussed above that generates detailed 3-D anatomical images without having to use radiation. How an MRA Scan Works An MRA test is similar to an MRI. As such, during the MRA, you’ll need to lie as still as possible so...
Background: Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a validated technique for evaluating cartilage health in developmental dysplasia of the hip (DDH), which can be a helpful prognosticator for the response to surgical treatments. dGEMRIC requires intravenous injection of gadolinium cont...
