methods fifty-three patients who were treated at the department of gastroenterology and hepatology of the university clinic essen from 2008 to 2013 included in this retrospective study. laboratory parameters were used to calculate non-invasive markers for liver fiibrosis. every patient underwent a liver biopsy within 6 months of the liver stiffness measurement. objectives autoimmune hepatitis (...

Purpose To determine the repeatability of magnetic resonance (MR) elastography-derived shear stiffness measurements of the intervertebral disc (IVD) taken throughout the day and their relationship with IVD degeneration and subject age. Materials and Methods In a cross-sectional study, in vivo lumbar MR elastography was performed once in the morning and once in the afternoon in 47 subjects witho...

BACKGROUND AND PURPOSE Malignancy correlates with hardness of tissues and US elastography can potentially analyze the stiffness of lesions. Our aim was to evaluate the utility of US elastography in the detection of malignant nodules and to investigate interobserver agreement with this technique. MATERIALS AND METHODS One-hundred three consecutive patients with 106 thyroid nodules were examine...

This letter announces and summarizes results obtained in [8] and considers several natural extensions. The aforementioned paper proposes a procedure to reconstruct coefficients in a second-order, scalar, elliptic equation from knowledge of a sufficiently large number of its solutions. We present this derivation and extend it to show which parameters may or may not be reconstructed for several h...

background: transient elastography (te) is a new modality for the diagnosis of liver fibrosis caused by various etiologies. this study was conducted to determine the accuracy of te in detecting the different stages of liver fibrosis in non-alcoholic fatty liver disease (nafld) patients. methods: medline/pubmed, embase, ovid, cochrane library, american college of physicians (acp) journal club, g...

BACKGROUND The most important aspect in the diagnostic approach of thyroid nodule is identifying the malignancy Elastography is a newly technique that measures the elasticity of tissue, after applying a external force, standardized control. US elastography is currently used in differentiation of malignant from benign lesions. PATIENTS This prospective study included 69 patients, mean age 50.0...

Changes in tissue mechanical properties, measured non-invasively by elastography methods, have been shown to be an important diagnostic tool, particularly for cancer. Tissue elasticity information, tracked over the course of therapy, may be an important prognostic indicator of tumor response to treatment. While many elastography techniques exist, this work reports on the use of a novel form of ...

Background: Elastography is an imaging technique which has been used in the last decades and its role breast masses characterization well established. However, value for predicting cancer grading yet to be studied. Objective: To determine of strain elastography prediction grade mammary ductal carcinoma. Methods: A cross sectional study enrolled 44 female patients with Breast Imaging Reporting D...

As an important means of medical imaging, elastic imaging is indispensable part mobile telemedicine. Ultrasound elastography has become a research hotspot because it can accurately measure soft tissue lesions. Displacement estimation the most step in ultrasound elastography. At present, phase zero search method accurate and fast displacement method. However, when exceeds 1/4 wavelength, invalid...
