title: Recent advances and future perspective in neuroimaging in neuropsychiatric systemic lupus erythematosus.
abstract: Involvement of the central nervous system (CNS) is one of the most important complications of systemic lupus erythematosus (SLE), occurring in 14-75% of SLE patients. Neurological and psychiatric involvement is mainly manifested as cerebrovascular disease, seizures, cognitive impairment, headaches and psychosis. However, diagnosis of brain involvement in SLE (i.e., neuropsychiatric lupus: NPSLE) as well as understanding of pathogenetic mechanisms still remains a difficult challenge. Although a wide range of neurodiagnostic tools have been used in the last decade to assess CNS involvement, no single technique has proven to be definitive or reliable. Since neurometabolic impairment, neurochemistry and perfusion abnormalities in NPSLE may precede anatomic lesions, new functional techniques such as magnetic resonance spectroscopy, diffusion and perfusion weighted imaging, and magnetization transfer imaging may be useful in order to indentify pathologic changes unrevealed by conventional imaging. So these new diagnostic tools could modify diagnostic and therapeutic approaches to this major unsolved problem, also shedding some light on the physiopathology of CNS disease in SLE.
