Elastografía hepática y otras secuencias avanzadas de RM (RM multiparamétrica) / Hepatic Elastography and Other Advanced MRI Sequences (Multiparametric MRI)

La fibrosis es un destino donde convergen variados trastornos hepáticos. Al tratarse de un proceso dinámico y reversible, su detección temprana y una intervención terapéutica oportuna, pueden frenar su progresión. La elastografía por resonancia magnética (ERM), es un método no invasivo con notable eficacia para la valoración del grado de fibrosis hepática. La tendencia actual es combinar esa técnica con secuencias de cuantificación de lípidos y hierro, lo cual permite un abordaje multiparamétrico de los trastornos difusos del hígado.

Fibrosis is a common destination where multiple liver disorders converge. Due to its dynamic and reversible process, an early detection and timely therapeutic intervention can interrupt its progression. Magnetic Resonance Elastography (MRE) is a non-invasive method with remarkable efficacy for assessing the degree of liver fibrosis. The current trend is to combine this technique with lipid and iron quantification sequences, which allows a multiparametric approach to diffuse liver disorders.

Ultrasound Elastography – Implications in the Head and Neck Region.

Ultrasound elastography (USE) is a method to assess the mechanical properties of tissue, by applying stress and detecting tissue displacement using ultrasound.1 It is based on the principle that malignant tissues are harder than the nonmalignant tissues. While histopathology is a gold standard, USE is a noninvasive method for differentiating benign and malignant lesions in multiple organs. Ultrasonography is used widely as diagnostic means because it is cost-effective, easy to use, and provides information of high resolution. However, no single ultrasound criterion has sufficient diagnostic accuracy and has limited sensitivity or specificity. The aim of this review is to provide an overview on the uses of USE in the head and neck region.
