What to Expect in an MRI for the Head and the Brain.

As the protons move back to their original alignment, they emit energy. The MRI machine captures this energy to create pictures. Radio waves transmit a signal to a computer which then processes MRI images. Because an MRI provides clear pictures of soft tissues, it's a reliable tool for diagnosing brain conditions..
