There's nothing for you to worry about, it has nothing to do with your spine. It is simply a 'goof' with the machine that changes the radiologists image. Kind-of-like if you dripped you Coca-Cola on a photograph, this would be an artifact that doesn't actually change what you are taking a picture of. A pulsation artifact specifically is caused by the flow of your cerebrospinal fluid (the fluid that encases and protects your brain). It flows within you spinal canal therefor causing movement. You know how they ask you to hold very still during the MRI. Well you can't really keep your body fluids still. Sooo you get these artifacts on your films. They are also referred to as ghost artifacts.

There are numerous kinds of artifacts that can occur in MRI. Some effect the quality of the MRI exam while others do not effect the diagnostic quality but may be confused with pathology.
