The decay of RF-induced NMR spin polarization is characterized in terms of two separate processes, each with their own time constants. One process, called T1, is responsible for the loss of resonance intensity following pulse excitation. The other process, called T2, characterizes the width or broadness of resonances. Stated more formally, T1 is the time constant for the physical processes responsible for the relaxation of the components of the nuclear spin magnetization v… WebMay 18, 2024 · Get Free Access to the Data Below for 10 Ads!

Webtrends showed that both vertebral height and depth increased consistently from T1 to T12, while vertebral width decreased from T1 to T3 and then increased from T4to T12, indicating a necking effect around T3/T4. A wedging ratio, the ratio of the anterior to posterior height of the vertebral bodies, was observed to range from 0.9 to 0.95 for T1-T12. WebMolecular motion of each spin near the Larmor frequency causes local magnetic field fluctuations with both T1 and T2 relaxation. The effectiveness of a dipole-dipole interaction at producing relaxation depends on 1) the types of spins; 2) their spatial relationship; and 3) their relative motion.
