CT-guided Stereotactic Body Radiation Therapy and MRI-guided Stereotactic Body Radiation Therapy for Prostate Cancer MIRAGE Study
Imaging modalities for image-guided SBRT can be either computed tomography imaging (CT), magnetic resonance imaging (MRI), or a combination of the two. This research is being done to help determine whether there are benefits to MRI-guidance over CT-guidance in patients who are receiving the same radiation dose by SBRT to …

GFAP Auto-immunity : a French Cohort Study
GFAP-IgG detected in serum or in cerebrospinal fluid, by tissue-based assay and confirmed by cell-based assay, are associated with encephalitis or meningoencephalitis of acute or subacute onset, less frequently with myelitis or optic disk edema. The characteristic MRI feature is brain linear perivascular radial gadolinium enhancement in the white matter …
