I never much cared for anatomy class. Dead bodies, the cold, and the smell were just not the way I liked to spend an afternoon. Every first year medical student spends hours in the anatomy room because learning the parts is important, but even more important is knowing what those parts do and how they work—functional anatomy. Thankfully, studying functional anatomy requires warm, live people who don’t usually smell. Let’s learn some parts without the smell because if you understand the parts, then you will understand the treatment. Getting down to the framework of your body is the skeleton which holds you upright, otherwise you would be a blob of gooey mush. As part of the skeleton, the spine is your backbone that bridges the span between your head and your butt. Because it is a bridge, the spine has passive, stationary structures (bones, ligaments, and discs) which don’t “do” anything except provide support for the whole body. However, these parts o...
Time for school, spine school. Millions of people experience some type of back pain every year. Billions of precious dollars are spent chasing the pain. With these types of epidemic numbers, everyone can benefit from some education about spine pain. The answers to what's, why's and how's can help to dispel fear, frustration, and disappointment. Fear comes from the unknown. Frustration comes from the unclear. Disappointment comes from the unrealized. All of these "un" words can be undone with health education at spine school. Epidemics are solved with knowledge.
Come with me to school. I take on the questions and give you straight answers based on the latest research about the spine. With the right information, you can get on the road towards recovery. This information is not meant to replace a proper, thorough evaluation by the right doctor. Everyone is different and every situation is different; thus, individual evaluation is critical. However, not every doctor has the knowled...
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 ...
