With body tumors the contrast may be spectacular when the tumor T2 is increased and its D* is also decreased so that the contrast produced by both of these tissue properties is positive and synergistic. In solutions of macromolecules and tissues the relaxation rate is much faster, i.e., the T2 time is shorter. Usually this is due to an increased water content of the tissue. "Nonspecific" usually means cause unclear/many possible causes and often implies "low concern". Epub 2016 Apr 4. T2 relaxation occurs due to tissue-particular characteristics, primarily those that affect the rate of movement of protons, most of which are found in water molecules. This slower motion is closer to the Larmor frequency. Clinics in diagnostic imaging (190). Learn more. In an MRI report, the white spots might be described as: "High signal intensity areas".

What is increased T2 signal on MRI report? Curr Probl Diagn Radiol. It really concerns me since i seem to be having a number of issues. T2 relaxation, also known as spin-spin relaxation or transverse relaxation, refers to the progressive dephasing of spinning dipoles resulting in decay in the magnetization in the transverse plane (M xy).Following a radiofrequency pulse, this form of relaxation occurs with the time constant T2, where T2 is the time it takes for the transverse magnetization vector to decay to 1/e or 37% of its . It is very common and usually clinically insignificant. By using our website, you consent to our use of cookies.
