WebTissues with a short T1 appear bright because they regain most of their longitudinal magnetization during the TR interval and produce a stronger MR signal. Tissues with a long T1 appear dark because they do not regain much longitudinal magnetization during the TR interval and produce a weaker MR signal. WebThe questioned apex in the patients with trapped fluid showed mixed MR signal characteristics (low to high T1 signal, high T2 signal). CT scans confirmed nonexpansile air-cell opacification. Conclusion: Asymmetric fatty marrow in the petrous apex and petrous air-cell effusions have characteristic MR and CT features that facilitate their correct diagnosis. brooks rehabilitation amelia island

WebCSF is dark on T1-weighted imaging and bright on T2-weighted imaging. A third commonly used sequence is the Fluid Attenuated Inversion Recovery (Flair). The Flair sequence is similar to a T2-weighted image except that the TE and TR times are very long. By doing so, abnormalities remain bright but normal CSF fluid is attenuated and made dark. Web10 Oct 2024 · T1 and T2 signals. The MR signal is created by the precession of the nuclei in the xy plane in-phase, which creates a net magnetisation. This magnetisation precesses at the Larmor frequency inducing an electric voltage in the receiving coils. This electric signal is a sinusoidal wave of the same frequency as the net nuclei precession. brooks rehabilitation clermont fl
