La elastografía por resonancia magnética es un método no invasivo y eficaz, cuyos resultados tienen concordancia con la biopsia hepática, presenta. O procedimento de elastografia em tempo real foi realizado por dois operadores independentes, cegos entre si e para o resultado da biópsia hepática. Resumen. La fibrosis es un destino donde convergen variados trastornos hepáticos. Al tratarse de un proceso dinámico y reversible.

Endoscopic ultrasound EUS elastography of the liver. A year-old woman with no previous medical history, except a lumbar vertebra broken at elastoggrafia age of 35, was first admitted because of abdominal pain in the right hypochondria for the last few weeks, together with anorexia and weight loss of 6 kg.
This biopsy confirmed the diagnosis of cholangiocarcinoma. Eur J Gastroenterol Hepatol. Ultrasonographic diagnosis of hepatic fibrosis or cirrhosis. A liver solid lesion in segment IVB, 6 x 5. Souto 1,2A. Tissue elasticity is usually uniform in benign lesions, with stiffness ranging from soft to intermediate colors yellow and green ; on the other hand, malignant tumors grow in elastohrafia disorganized manner, and show heterogeneous patterns with hard tissue blue color 4,5.
Sampling error and intraobserver variation in liver biopsy in patients with chronic HCV infection. A non invasive method to evaluate fibrosis in chronic HCV patients Summary Liver biopsy is the current “gold standard” for evaluating liver fibrosis but it is an invasive procedure, unsuitable for monitoring disease progression. Imaging of the elasticity properties of tissue-a review.
Formulation and application of a numerical scoring system for assessing histological activity in assymptomatic chronic active hepatitis. Finally, the patient underwent an endoscopic retrograde cholangio-pancreatography that confirmed the presence of a 2-cm filiform stenosis in the middle portion of the common bile duct Fig.
The technology is based on the detection of small structure deformations within the B-mode image as caused by compression, so that strain is smaller in hard tissue versus soft tissue. Virxe da Xunqueira Hospital. The remaining parameters, including tumor markers, were completely normal. In Pathology of the liver. Noninvasive assessment of liver fibrosis by measurement of stiffness in patients with chronic hepatitis C.
An appraisal of the pathological assessment of liver fibrosis. Liver biopsy is the current “gold standard” for evaluating liver fibrosis but it is an invasive procedure, unsuitable for monitoring disease progression.
Different elasticity values are marked with different colors resulting in different tissue elasticity patterns. Elastography for detecting hepatic fibrosis: Fibroscan and Fibrotest to assess fibrosis in HCV with normal aminotransferases.

We present two images demonstrating the feasibility of a EUS-guided elastographic study of the liver, both standard and second-generation.
J Gastrointestin Liver Dis ; In order to obviate the bias related to the subjective interpretation of the color map, a quantitative analysis is possible with second-generation elastogragphy.
Data published on this new technique are scarce, but malignant lesions show higher strain elsstografia when compared to benign lesions 5.
