Instructions and help about NEWSLETTER OF THE SECTION FOR MAGNETIC RESONANCE TECHNOLOGISTS

hello my name is dr erin gomez and this is a brief overview of magnetic resonance and a basic mri spin echo sequence let's talk about protons we have protons in the fat muscle and sugars within our body and of course within water remember that a significant portion of our bodies consists of water and that a hydrogen atom is just a proton one positron and one electron with a positive and a negative pole because of this each of these protons is capable of acting like a bar magnet usually the orientation of these protons is random but they can be influenced by an external magnetic field at the most basic level an mri scanner is a giant magnet and generates its own magnetic field which we can call b0 when protons are placed within this magnetic field they'll line up parallel or anti-parallel to the primary magnetic field with a small majority aligning with the direction of the primary magnetic field just going with the flow this generates what is referred to as the net magnetization vector
