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.

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. A liver solid lesion in segment IVB, 6 x 5. Optimal stiffness cut-off values hepattica fibrosis stage assessment were determined by ROC curve analysis in 60 patients with concomitant liver biopsy specimens that contain more then 10 portal tracts.

Clinical significance of the serum N-terminal propeptide of procollagen type III. Souto 1,2A. Eur J Gastroenterol Hepatol. Transient liver elastography is mainly used for the quantification of liver fibrosis. During EUS we performed an elastographic evaluation of the solid liver lesion, and obtained a heterogeneous blue-predominant pattern with slight green areas and red lines resulting in a geographic appearance characteristic of malignant tumors ; the mass was clearly differentiated from normal tissue Fig.

Prevalence and factors elastogratia with failure of liver stiffness measurements using FibroScan hepatuca a prospective study of examinations.

In order to obviate the bias related to the subjective interpretation of the color map, a quantitative analysis is possible with second-generation elastogragphy. A helical CT scan identified an enlarged choledocus with an associated dilatation of the intrahepatic biliary tree. Discussion Transient liver elastography is mainly used for the quantification of liver fibrosis.

To evaluate the interest of hepatic elastography for assessment and monitoring of elasstografia fibrosis in chronic HCV patients. Prospective comparison of transient elastography, Fibrotest, APRI and liver biopsy for the assessment of fibrosis in chronic hepatits C.
This is possible due to hepaticz proximity of the liver mainly left liver lobe to the gastric and duodenal wall. Saftoiu A, Vilman P. We present two images demonstrating the feasibility of a EUS-guided elastographic study of the liver, both standard and second-generation.
Portal Hemodynamics by duplex hepahica sonograpgy in different grades of cirrhosis. Endoscopy ; 38 4: Journal of Acquired Immune Deficiency Syndromes. With this method, two different areas A and B from the region of interest are selected: 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.
