Magnetic resonance imaging (MRI) of the spine is a noninvasive procedure that uses powerful magnets and radio waves to create pictures of the spine area, including the vertebrae (spine bones), the spinal cord, and the spaces between the vertebrae through which the nerves travel.

How the test is performed
You will be asked to lie on a narrow table, which slides into a large tunnel-like tube. The health care provider may inject a dye through one of your veins. This helps certain diseases and organs show up better on the images.
Unlike and computed tomographic (CT) scans, MRI does not use radiation. Instead, it uses powerful magnets and radiowaves. The magnetic field produced by an MRI forces certain atoms in your body to line up in a certain way. It's similar to how the needle on a compass moves ...
Restless legs syndrome or Ekbom Syndrome affects hundreds of people night after night, keeping them and their partners awake. It can even lead to sleep deprivation.
What are the symptoms of restless legs syndrome? The itching, burning sensation on the limbs and the endless need to move them as the sufferer tries to find a comfortable position in which to lie. Often it's necessary to get up and pace the floor, take a hot/cold bath, anything to get rid of the misery in the legs.
What causes restless legs? The cause is unknown, although recent research suggests that a single unknown gene causes many of the cases. It is known that RLS is hereditary, with some families having several members suffering from the disorder. RLS is associated with iron deficiency, disorders of the peripheral nerve (e.g. neuropathy) and various other movement disorders (such as Parkinson’s disease). However, the cause of RLS for most patients remains unknow...
A lumbosacral spine MRI uses powerful magnets and radio waves to create pictures of the structures that make up the spine, the spinal cord, and the spaces between the vertebrae, through which the nerves travel.
Conventional radiography and computed tomographic ( CT ) imaging use potentially harmful radiation (x-rays) that passes through a patient to generate images. Magnetic resonance imaging (MRI) is based on the magnetic properties of atoms, and there is no exposure to the same type of radiation used in x-rays and CT scans.
A powerful magnet generates a magnetic field roughly 10,000 times stronger than the Earth's. A very small percentage of hydrogen atoms within the body will align with this field. Radio wave pulses are broadcast towards the aligned hydrogen atoms in tissues of interest, returning a signal of their own. The slight differences of those signals from different tissues enables MRI to tell the difference between various organs, and potentially, prov...
