- ItemAcute Cerebrovascular events associated to hemolytic uremic syndrome: Description of two pediatric cases(2017) Lopez, M.; Huete, Isidro; Hernández Chávez, Marta IsabelIntroduction: Diarrhea-associated Hemolytic Uremic Syndrome (D+HUS) is a multisystem disorder in which neurological involvement (35 to 50%) is associated to adverse outcome. An important cause of a permanent neurological impairment is the cerebrovascular pathology. Objective: To report two pediatric cases of D+HUS with severe neurological involvement due to cerebrovascular disease, and review available literature. Clinical cases: Two previously healthy 15- and 21-month-old children debuted with seizures and impairment of consciousness within the first week of a D+HUS. Both presented hypertension, severe acute renal failure, and focal motor deficit. One child showed significant improvement in neurologic status after five sessions of plasmapheresis. Brain magnetic resonance showed in the first child multiple bilateral infarcts of small vessels and lesions of white matter. In the second patient, large bilateral infarcts on both middle cerebral arteries territories were identified. One year after the acute event, both children showed functional impairment; The first patient evolved with language delay and spastic hemiparesis; the second patient with spastic quadriparesis, epilepsy with poor seizure control and marked functional impairment. Conclusion: Although most of the children with D+HUS and brain involvement do not have long-term sequelae, cerebrovascular disease in the acute period causes permanent damage, and in addition to the management of electrolyte disturbances, hypertension, and renal failure, therapies directed at specific pathophysiological mechanisms that trigger vascular compromise may improve prognosis.

- ItemImaging artifacts in MRI simulators(2011) Carrasco, S.; Huete, Isidro; Zunino, R.Artifactual images are created in the process of imaging. They are images that distort reality, i.e. they do not correspond to the image but they arise from them and are false. This paper describes image artifacts in MR that can lead to misdiagnosis, analyzes their causes and reviews the most common imaging artifacts.

- ItemInversion recovery MRI in idiopathic Parkinson disease is a very sensitive tool to assess neurodegeneration in the substantia nigra: Preliminary investigation(2006) Raff, Ulrich; Hutchinson, Michael; Rojas, Gonzalo M.; Huete, IsidroRationale and Objectives. Segmented inversion recovery (IR) ratio imaging (SIRRIM) has been established as a sensitive tool to assess neurodegeneration of the substantia nigra pars compacta (SNC) in patients with idiopathic Parkinson disease (IPD). The obtained results suggest the possibility of magnetic resonance imaging (MRI) as a biological marker for IPD. The strength and a parsimonious analysis of the technique are discussed to assess the potential of using MRI as a biological marker for IPD and improve the differential diagnosis of sporadic Parkinson disease. Our hypothesis states that the magnetic resonance SIRRIM technique allows direct visualization and quantitation of neural cell loss in the SNc and therefore could become a reliable biological marker for Parkinson disease. To achieve this goal, some key aspects of data acquisition and data analysis need to be addressed. The clinical impact of the SIRRIM technique could be considerable, considering that it might become a viable surrogate to other techniques.
- ItemMedios de contraste intravascular en tomografía computada y resonancia magnética: lo que el cílnico necesita saber(2020) Garrido Cisterna, Francisco Javier; Pesenti Anjel, José Patricio; Riquelme Pizarro, Carlos Rodrigo; Huete, IsidroIntroducción: los medios de contraste en radiología se utilizan para mejorar la visibilidad de los tejidos normales y patológicos, lo que permite distinguirlos entre sí mediante la modificación de las características de imagen de los tejidos. Permite no solo una mejor evaluación morfológica de las lesiones, sino también una evaluación cinética funcional y de contraste. Objetivos: presentar una revisión actualizada sobre los medios de contraste intravascular en radiología, con énfasis en los conceptos que el médico clínico no radiólogo debe tener presente al momento de su indicación. Métodos: se realizó una revisión bibliográfica de literatura radiológica relevante sobre medios de contraste intravascular: clasificación, indicaciones, contraindicaciones y precauciones que debe adoptar el médico clínico. Resultados: aunque los medios de contraste en radiología tienen un excelente perfil de seguridad, su uso no está exento de riesgos y debe basarse en criterios apropiados después de una evaluación clínica exhaustiva, ponderando riesgos y beneficios para cada paciente individual. Conclusión: la comunicación entre médicos tratantes, nefrólogos y radiólogos es funda-mental para evaluar casos clínicos complejos o que requieran consideraciones especiales al momento de indicar la administración de un medio de contraste intravascular.
