E.2.1 | Main objective of the trial |
Determinar si se detectan mayor número de lesiones emergentes con dosis acumulada de GADOVIST 0.2 mmol/kg ( administrada como 0.1 mmol/kg + 0.1 mmol/kg) en comparación con dosis única de GADOVIST 0.1 mmol/kg en pacientes con Síndrome Clínico Aislado o recaída de Esclerosis Múltiple.
To determine whether a greater number of enhancing lesions is detected in patients with CIS or relapsing MS using a cumulative dose of GADOVIST 0.2 mmol/kg (administered as 0.1 + 0.1 mmol/kg), compared with a single dose of GADOVIST 0.1 mmol/kg |

- Whether a greater proportion of CIS patients fulfill the criteria for demonstration dissemination in time (McDonald criteria) - Whether a greater proportion of relapsing MS patients demonstrate disease activity - Degree of contrast enhancement - The number of small enhancing lesions (<1 cm) detected; - The number of enhancing lesions specific to location (e.g. periventricular and subcortical lesions); - Lesion appearance (nodular, ring) |

E.4 | Principal exclusion criteria |
- Mujeres embarazadas o en período de lactancia. - Excluir la posibilidad de embarazo: por test (suero u orina ßHCG) durante 24h antes de la administración del agente en estudio, o por esterilización quirúrgica, o post menopausia, con un mínimo de 1 año de historia sin menstruación. - Pacientes con marcapasos, material magnético como grapas quirúrgicas o cualquier otra condición que excluya proximidad a campos magnéticos fuertes. - Pacientes que sufren de claustrophobia severa - Pacientes con alergia conocida a uno o más ingredientes del agente de estudio. - Pacientes que han participado previamente en este studio o en un ensayo clínico del medicamento en investigación durante los 30 días previos al examen de RM. - Pacientes con cualquier condición o otras circunstancias las cuales significaran una disminución de la posibilidad de obtener datos fiables, o de lograr los objetivos del estudio (ejemplo: dependencia a las drogas, trastornos psiquiátricos, demencia, o otras razones para la baja expectativa de seguimiento con las instrucciones del investigador y/o el seguimiento post tratamiento. - Pacientes en tratamiento actual con corticoesteroides o que lo han recibido durante los últimos 30 días anteriores al MRI - Pacientes con diagnóstico establecido de microangiopatia. - Pacientes que han empezado tratamiento inmunosupresivo antes de MRI - Deterioro severo de la función renal conocido - Candidato a trasplante de hígado
