In such cases the attending physician who ordered the study asks the radiologist who interpreted the study to elucidate further and determine whether Understanding radiology reports can be challenging. Can a person have such a finding and still be normal? This is related to the rate of rotation and translation of the water molecule or adjacent dipoles. As motion, and therefore the local field fluctuations, decreases below the Larmor frequency in tissues and tendons,dipoles that are aligned with the main magnetic field start contributing to T2 relaxation by causing local variations in precession rate.
