Here are a few Frequently Asked Questions on MRI Scans.
Magnetic Resonance Imaging (MRI) is a technique that uses a magnetic field and radio waves to create detailed images of the organs and tissues within the body. MRI Scan has immense application in patients having soft tissue growths and tumors.
Most MRI machines are large, tube-shaped magnets. When you lie inside an MRI machine, the magnetic field temporarily realigns water molecules in your body. Radio waves cause these aligned atoms to produce faint signals, which are used to create cross-sectional MRI images — like slices in a loaf of bread
In most cases, you must not to eat or drink anything before the scan, unless otherwise as adviced by NHS.
A single scan may take a few seconds or 3 to 8 minutes. You may be asked to hold your breath during short scans. The total scan lasts 15 to 90 minutes, depending on the size of the area being scanned and how many images are needed.
