As you already know, our bodies are largely composed of water. The hydrogen atoms in water are magnetic. When exposed to the MRI magnetic field, they align with the field.

The radio waves disrupt the atoms polarity and a sensor measures the time taken for the atoms to realign.

The MRI is capable of showing detailed pictures of soft tissues in the body. For instance, it can show detailed images of the brain and other organs. What you need to know is that the machine cannot show certain areas.

For example, it cannot display detailed images of hard bone and air. Since these areas do not give an MRI signal, they appear black on the image. When it comes to blood, soft tissues, bone marrow, and spinal fluid, they may appear black or white.

This depends on the amount of water and fat present in the tissue. It also depends on the settings used during the MRI scan. One of the most popular MRI machines in use today is the Open Upright MRI.

Designed to look like a bagel sliced in half, its perfect for claustrophobic patients. The reason for this is that it has more room inside and is completely open in front. Due to the shape of the MRI, it is unable to capture certain parts of the body.
