Background White matter hyperintensities (WMH) lesions on T2/FLAIR brain MRI are frequently seen in healthy elderly people. Whether these radiological lesions correspond to irreversible histological changes is still a matter of debate. We report the radiologic-histopathologic concordance between T2/FLAIR ...
Objective:To describe the normally enhancing intracranial structures on fluid-attenuated inversion recovery (FLAIR) MRI and evaluate the usefulness of postcontrast FLAIR images of the brain in the assessment of enhancing lesions by comparing postcontrast FLAIR imaging with postcontrast T1-weighted (T1-W...
For each patient, T1, Gd-enhanced T1 (T1CE), T2, and fluid-attenuated inversion recovery (FLAIR) sequences were obtained. MICCAI_BraTS_Training contains three segmentation labels of abnormality: Gd-enhancing tumor (ET), peritumoral edema (ED), and necrotic and non-enhancing tumor core (NET...
