Hi I ought to take Prednisolon (rheumatologist) for a newly found autoimmune disorder but I have several hormone issues too and will have a MRI scan cranium in about 4 weeks for a pituary diagnosis. My 'normal' physician, however, isn't sure if the Prednisolon would influence the imaging and therefore wants that I delay the Prednisolone. My autoimmune illness (not yet clear which sort, supposed mixed connective tissues disease) gets worse. Does anyone know, if the cortisone has any affect in regard to the MRI? Thank you very much.
