      Pathologic lesions can be separated into four major groups by their specific signal characteristics on the three basic images: T2-weighted, proton density-weighted (PD)/FLAIR, and T1-weighted. Since studies have shown that T2-weighted images are most sensitive for detecting brain pathology, patients with suspected intracranial disease should be ...

      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.

      The number of T2-hyperintense brain and spinal cord lesions plus T1-hypointense brain lesions was recorded at baseline and follow-up. 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 ...
