Abstract

Magnetic resonance imaging has become a fundamental tool for the evaluation of head and neck tumors. The anatomic details that magnetic resonance images provide are fundamental for diagnosing, characterising, and staging both primary tumors and lymph node metastases.

In addition to technical improvements in anatomic sequences, such as Dixon techniques to improve fat suppression, other sequences being developed, such as diffusion and perfusion, provide molecular, biological, and physiological information about the tumor and are yielding imaging biomarkers that can help in determining the tumor's biology at the time of diagnosis and in the follow-up of the disease. Magnetic resonance imaging also provides very useful information about the response to treatment.

Keywords:

Resumen

La resonancia magnética se ha convertido en una herramienta fundamental en la valoración de la patología tumoral de cabeza y cuello. Los detalles anatómicos que proporcionan las imágenes de resonancia son fundamentales para diagnosticar, caracterizar y estadificar tanto la tumoración primaria como las metástasis ganglionares.

Además de las mejoras técnicas en las secuencias anatómicas, como es el caso del Dixon para mejorar la supresión de la grasa, se están desarrollando otras secuencias como son la difusión y la perfusión, que dan información molecular, biológica y fisiológica del tumor proporcionando biomarcadores que pueden ayudar a conocer la biología del tumor en el momento del diagnóstico y posteriormente a monitorizar la enfermedad, y facilitan información muy relevante de la respuesta al tratamiento.
