WebApr 21, 2024 · Introduction. Diffusion-weighted imaging (DWI) is central to the diagnostic workup for patients with glioma (Barajas et al., 2016; Kolakshyapati et al., 2024; Zeng et al., 2024; White et al., 2024).A sign of poor prognosis is the presence of tumor hyperintensities on the DWIs, which are often referred to as regions of reduced diffusivity. WebOct 1, 2024 · Once conventional sequences for MS are positive, the DWI hyper signal intensity is because of T2 shine through effect (Fig. 5C and D ).

WebDWI is the first sequence to show pathology, and can demonstrate hyperintensity in the affected areas within hours of the inciting event. Increased T2-signal can typically be seen after approximately 24 hours in the early subacute phase. 7 This is due to increased edema in the injured gray matter structures. Acute Hypertensive Encephalopathy WebThe hyperintensity on T2-weighted imaging supposedly results from an abnormal myelin signal [ 1 ]. Increased signal on diffusion-weighted sequences may be seen with normal, decreased, or elevated ADC values within the basal ganglia and pons and is most consistent with myelin destruction [ 9, 10] ( Fig. 2C ).
