ABSTRACT
Sonographic elastography is a new technique for measurement of the tissue stiffness, and is currently under investigation for tissue characterization in several anatomic sites. In recent years, real-time Ultrasonography elastography (USE) modes have appeared on commercially available clinical ultrasound machines, stimulating an explosion of research into potential oncologic and non-oncologic clinical applications of USE. Preliminary evidence suggests that USE can differentiate benign and malignant conditions accurately in several different tissues. The principles underlying elastography are that tissue compression produces strain (displacement) within the tissue – which is lower in harder tissues than in softer tissues and that malignant tissues are generally harder than normal surrounding tissue. Therefore, elastography might yield clinical information useful in diagnosing cervical metastasis and improving prognosis in oral cancer .The purpose of this review is to highlight a promising new ultrasound technique, known as elastography, which measures the characteristics of tissue compliance.
ABSTRACT
La hipertensión portal en el curso natural de las enfermedades hepáticas es una de las complicaciones más frecuentes resultado del aumento de la resistencia vascular hepática que determina el desarrollo de otros sucesos responsables de la mayor mortalidad en pacientes con hepatopatías. En consecuencia, el conocimiento de la fisiopatología de la hipertensión portal y de sus causas representa un factor importante para su adecuado manejo y el de las demás complicaciones relacionadas. Es así como se cuentan con métodos diagnósticos de diferentes tipos para la detección temprana y adecuada de dicha entidad; lo cual, además, corresponde al objetivo de la presente revisión: dar una mirada a los métodos diagnósticos utilizados para la detección de hipertensión portal, disponibles en la actualidad.
Portal hypertension is one of the most frequent complications in the natural course of liver disease. It results from increased hepatic vascular resistance and determines the development of other events responsible for increased mortality in patients with liver disease. Consequently, knowledge of the pathophysiology of portal hypertension and its causes is an important factor for handling it and related complications proper. Explanation of the various diagnostic methods for early and appropriate detection is one of the objectives of this review which will take a look at diagnostic methods available and in use for the detection of portal hypertension.
