ELASTOGRAFIA HEPATICA PDF

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.

J Gastrointestin Liver Dis ; An appraisal of the pathological assessment of liver fibrosis. Median liver stiffness was A year-old woman with heparica previous medical history, except a lumbar vertebra broken at the 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.

Liver biopsy is the current “gold standard” for evaluating liver fibrosis but it is an invasive procedure, unsuitable for monitoring disease progression. Transient liver elastography is mainly used for the quantification of liver fibrosis.

Souto 1,2A. How to assess liver fibrosis and for what purpose? However, there are few elastografiz evaluating its usefulness in the differential diagnosis of solid liver lesions. In the second-generation elastography study, the strain ratio obtained was With this method, two different areas A and B from the region of interest are selected: Transient elastography Fibroscan a novel noninvasive sensitive method for the assessment of liver fibrosis in chronic hepatitis C: A non invasive method to evaluate fibrosis in chronic HCV patients.

This is possible due to the proximity of the liver mainly left liver lobe to the gastric hspatica duodenal wall.

Evaluation of fibrosis regression using fibroscan in HCV responder patients. The remaining parameters, including tumor markers, were completely normal. A prospective controlled study abstract. This biopsy confirmed the diagnosis of cholangiocarcinoma. Journal of Acquired Immune Deficiency Syndromes.

The median in 25 controls was 4. 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. La revue de medicine interne. Universidade de Medicina; Alfa Interferon improves liver fibrosis in chronic hepatitis C.

Different elasticity values are marked with different colors resulting in different tissue elasticity patterns.

In order to obviate the bias related to the subjective interpretation of the color map, a quantitative analysis is possible with second-generation elastogragphy.

Optimal stiffness cut-off values hepatlca fibrosis stage assessment were determined by ROC curve analysis in 60 patients with concomitant liver biopsy specimens that contain more then 10 portal tracts.

Impact of Pegylated interferon alfa 2b and ribavirin on liver fibrosis in patients with chronic hepatitis C. During EUS we performed an elastographic evaluation of the solid liver lesion, and obtained a heterogeneous blue-predominant pattern with slight green elaastografia and red lines resulting in a geographic appearance characteristic of malignant tumors ; the hepatic was clearly differentiated from normal tissue Fig.

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 a disorganized manner, and show heterogeneous patterns with hard tissue blue color 4,5. In Pathology of the liver. Imaging of the elasticity properties of tissue-a review.

Preliminary results in 49 patients. Elastography for detecting hepatic fibrosis: The probe is pressed against the wall with only the pressure needed for an optimal and stable B-mode image at 7. We present two images demonstrating the feasibility of a EUS-guided elastographic study of the liver, both standard and second-generation.
