Valor de la secuencia coronal-T1W agregada al protocolo de imágenes de resonancia magnética en casos de dolor lumbar

Palabras clave: dolor de la región lumbar, imagen por resonancia magnética

Resumen

Introducción. La resonancia magnética (RM) es el método de imágenes diagnósticas más apropiado para investigar el dolor lumbar. Dado que este es muy común, son muchas las resonancias magnéticas de este tipo que se hacen.
Objetivo. Analizar los hallazgos extraespinales que se pueden detectar al agregar la secuencia coronal T1W al protocolo de imágenes de RM para el dolor lumbar y evaluar su efecto clínico.
Materiales y métodos. En el 2015 se agregó una secuencia coronal ponderada en T1W al protocolo de resonancia magnética lumbar de rutina de nuestro hospital. Se evaluaron retrospectivamente 969 imágenes solicitadas en casos de dolor lumbar y realizadas con este protocolo. Los hallazgos obtenidos a partir de dichas imágenes se agruparon luego como asociados con el dolor lumbar (categoría 1) y no asociados con el dolor lumbar (categoría 2). Se evaluó, asimismo, si los hallazgos extraespinales registrados podían detectarse en imágenes axiales y sagitales convencionales.
Resultados. Noventa y seis (63 %) de los hallazgos extraespinales se asociaron con lumbalgia (categoría 1) y 56 (37 %) correspondieron a la categoría 2. El 78 % de los hallazgos extraespinales se detectaron solo en imágenes coronales-T1W y no en las convencionales.
Conclusión. La secuencia coronal-T1W agregada al protocolo de rutina de la resonancia magnética lumbar puede ayudar a detectar afectaciones extraespinales y guiar el tratamiento clínico.
