      5. Cysts are low in intensity on T1-weighted and high in intensity on T2-weighted sequences. [On MRI, simple cysts are hypointense on T1-weighted images and hyperintense on T2.] Image stacks for The Interactive Viewing Mode. Furthermore please provide the stack of images (as JPG files) for each. cross-sectional study in zip files for the ...

      A CT scan of the head was normal, but a magnetic resonance imaging (MRI) scan documented T1-hypointense and T2-hyperintense signal in the cortex and gray–white matter junction in the left temporal lobe. CSF obtained by lumbar puncture contained 50 WBCs/mm3 (90% mononuclear cells) and 300 RBCs/mm3, glucose in the normal range (70 mg/dL), and ...

      MRI: iso-/hypointense on T1, hyperintense on T2, haemorrhagic lesions and melanotic melanoma may be hyperintense on T1. Dural metastases may be seen as extension from adjacent bone metastases or isolated to the dura (hematogeneously disseminated), focal contrast enhancing mass is more common than diffuse meningeal thickening with enhancement.

      Two relaxation rates, T1 and T2 relaxation times, are measurable. The T1 relaxation rate is time for 63 percent of protons to return to their normal equilibrium state, while T2 relaxation rate is time for 63 percent of protons to become dephased owing to interactions among adjacent protons.

      While advanced imaging techniques such as diffusion tensor imaging can detect changes that parallel brain myelination, stages of myelination are most consistently and easily judged using relative T1 and T2 intensity where T1 and T2 shortening (T1 hyperintense, T2 hypointense signal) indicate appropriate myelination of a brain structure 2.
