RESUMO
The objective of this article is to review the literature on neuroimaging in small vessel disease. A review was carried out through the Pubmed search engine, without a filter of years, using terms such as: cerebral small vessel disease; white matter hyperintensity; brain microbleed; WBC. Small vessel disease is the most common vascular pathology. Its basis is in the affectation of the small cerebral vessels that eventually causes an alteration in the bloodbrain barrier. Its clinical implication is highly relevant. Using magnetic resonance imaging, different expressions of the disease have been observed, such as white matter hyperintensities, microbleeds or lacunar infarcts. Other more recent techniques, such as brain blood flow measurements, are helping to increase understanding of the pathophysiology of this disease. (AU)
El objetivo de este artículo es realizar una revisión bibliográfica sobre la neuroimagen en la enfermedad de vaso pequeño. Se ha realizado una revisión a través del buscador PubMed, sin filtro de años, usando términos como: cerebral small vessel disease; white matter hyperintensity; cerebral microbleed; CMB. La enfermedad de vaso pequeño es la patología vascular más común. Su base está en la afectación de los pequeños vasos cerebrales que causa a la larga una alteración en la barrera hematoencefálica. Su implicación clínica, dada la prevalencia que presenta, es muy relevante. Mediante la resonancia magnética, se han podido objetivar diferentes expresiones de la enfermedad tales como las hiperintensidades de sustancia blanca, los microsangrados o los infartos lacunares. Otras técnicas más recientes como las mediciones del flujo cerebral, están ayudando para comprender mejor la fisiopatología de esta enfermedad. (AU)
