WebFeb 1, 2024 · For T2-weighted sequences (STIR versus mDixon T2-weighted TSE), the ratios measured 3.5 ± 3.4 versus 5.7 ± 1.6, respectively ( P < .001) at the submandibular level and 3.3 ± 3.4 versus 7.4 ± 2.4, respectively ( P < .001) at the supraclavicular level. WebIt is characterized by the spin–spin relaxation time, known as T2. In an idealized system, all nuclei in a given chemical environment, in a magnetic field, relax with the same frequency. However, in real systems, there are minor differences in chemical environment which can lead to a distribution of resonance frequencies around the ideal.
