Imágenes de resonancia magnética nuclear del cerebro en la esclerosis múltiple
Lancet (London, England)
|November 14, 1981
Resumen
Las imágenes de resonancia magnética nuclear (RMN) revelan significativamente más lesiones en pacientes con esclerosis múltiple (EM) que las tomografías computarizadas (TC). Las imágenes de RMN ofrecen una visión más completa de las anomalías cerebrales relacionadas con la EM.
Área de la Ciencia:
- La neuroimagen es una técnica de neuroimagen.
- Neurología Neurología.
- Radiología Radiología.
Sus antecedentes:
- La esclerosis múltiple (EM) es una enfermedad desmielinizante que afecta al sistema nervioso central.
- La detección precisa de las lesiones es crucial para comprender la progresión y el impacto de la EM.
Objetivo del estudio:
- Para comparar la eficacia de la tomografía computarizada craneal (TC) y la resonancia magnética nuclear (RMN) en la detección de lesiones en pacientes con esclerosis múltiple.
- Evaluar el potencial diagnóstico de las imágenes de RMN para identificar anomalías relacionadas con la EM.
Principales métodos:
- Diez pacientes con esclerosis múltiple se sometieron a una TC craneal de rayos X con y sin contraste.
- Los pacientes también se sometieron a imágenes de RMN utilizando una secuencia de inversión-recuperación.
- La detección y caracterización de las lesiones se realizaron utilizando ambas modalidades de imagen.
Principales resultados:
- La TC demostró 19 lesiones periventriculares, con dos pacientes que mostraban un agrandamiento ventricular moderado.
- Las imágenes de RMN identificaron 112 lesiones adicionales, que varían en tamaño, predominantemente en la región periventricular y el tronco cerebral.
- Las imágenes de RMN revelaron un número significativamente mayor de anomalías en comparación con la TC.
Conclusiones:
- Las imágenes de RMN demuestran un número sustancialmente mayor de lesiones en pacientes con esclerosis múltiple que en pacientes con TC.
- Las imágenes de RMN proporcionan un método más sensible para visualizar las anomalías cerebrales relacionadas con la EM, ofreciendo una escala de detección sin precedentes.
- Es necesaria una evaluación cuidadosa de las exploraciones de RMN para diferenciar las lesiones verdaderas de los artefactos y las estructuras anatómicas normales.

Nuclear Magnetic Resonance (NMR): Overview
Nuclear magnetic resonance (NMR) is a phenomenon exhibited by certain nuclei that can absorb characteristic radio frequency radiation under certain conditions. NMR has been extensively applied in molecular spectroscopy and medical diagnostic imaging. In both these applications, the molecule or subject under study is placed in a magnetic field and irradiated with radio frequency energy.
NMR spectroscopy generates a spectrum where the characteristic absorption frequencies of the sample are...

Atomic Nuclei: Magnetic Resonance
The number of nuclear spins aligned in the lower energy state is slightly greater than those in the higher energy state. In the presence of an external magnetic field, as the spins precess at the Larmor frequency, the excess population results in a net magnetization oriented along the z axis. When a pulse or a short burst of radio waves at the Larmor frequency is applied along the x axis, the coupling of frequencies causes resonance and flips the nuclear spins of the excess population from the...
Applications Of NMR In Biology
Nuclear magnetic resonance (NMR) spectroscopy is a very valuable analytical technique for researchers. It has been used for more than 50 years as an analytical tool. F. Bloch and E. Purcell formulated NMR in 1946 and won the 1952 Nobel Prize in Physics for their work. Biological macromolecules such as proteins, nucleic acids, lipids, and organic molecules including pharmaceutical compounds, can be studied using this versatile tool that exploits the magnetic properties of certain nuclei.

Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
Brain Imaging
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Multiple Sclerosis l: Introduction
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
