[On MRI, simple cysts are hypointense on T1-weighted images and hyperintense on T2.] Image stacks for The Interactive Viewing Mode.

      , it is assumed that T1 . hypointense. lesions indicate myelin destruction AND axonal decay, hence not all T2 lesion are also seen in T1, and that creates a subpopulation T2+/T1+, as well as the Gad enhancing ‘acute’ T1 lesions, Maybe not in this paper, we should think about completing MWF and DV . measurments. in those two lesion types ...

      MRI was sporadically reported [21]: (1) the normal thyroid gland was homogeneously hyperintense relative to the neck muscles on both T1- and T2-weighted images; (2) the tuberculous lesion showed an intermediate signal on both T1- and T2-weighted images, the signal intensity was higher than normal glandular parenchyma due to the presence of ...

      The lesions were identified by a single experienced neuroradiologist, who was blinded the patient’s clinical status. T2-hyperintense and T1-hypointense brain lesions were outlined using a semi-automated edge finding tool (JIM6, Xinapse systems, Aldwincle, UK).

      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.

First, a Bayesian-tissue-classification approach7 was used to automatically combine the normalized intensity-information in each patient’s registered T2-, proton-density- (PD), and T1-weighted magnetic resonance images in order to generate an automatically-segmented T2 lesion (aT2
