Abstract Shear wave elastography offers a new dimension to echocardiography: it measures myocardial stiffness. Therefore, it could provide additional insights into the pathophysiology of cardiac diseases affecting myocardial stiffness and potentially improve diagnosis or guide patient treatment. The technique detects fast mechanical waves on the heart wall with high frame rate echography, and converts their propagation speed into a stiffness value. A proper interpretation of shear wave data is required as the shear wave interacts with the intrinsic, yet dynamically changing geometrical and mat

Clinical assessment of myocardial ischemia based on visually-assessed wall motion scoring from echocardiography is semiquantitative, operator dependent, and heavily weighted by operator experience and expertise. Cardiac motion estimation methods such as tissue Doppler imaging, used to assess myocardial muscle velocity, provides quantitative parameters such as the strain-rate and strain derived from Doppler velocity.

We present a magnetic resonance elastography approach for tissue characterization that is inspired by seismic noise correlation and time reversal. The idea consists of extracting the elasticity from the natural shear waves in living tissues that are caused by cardiac motion, blood pulsatility, and any muscle activity. In contrast to other magnetic resonance elastography techniques, this noise-based approach is, thus, passive and broadband and does not need any synchronization with sources.

Elastography is a method that allows to quantify mechanical properties of biological tissues. In medical imaging, this last technique has been developed mainly in ultrasound (US) and in magnetic resonance imaging (MRI). Both imaging techniques have advantages and drawbacks depending on the organs and pathologies investigated. In this presentation we focused on two organs, where each technique has its advantage to investigate mechanical properties: brain and muscle. In brain, the preferred technique is MRI since US propagation is very complicated through the skull bone. Taking advantage of 3D a

Today, heart failure remains one of the most important public health problems. The leading pathogenetic mechanism of heart failure is stagnation in the systemic circulation, causing affection of one of the main target organs – the liver. Prolonged stagnation in the liver in combination with hypoperfusion of hepatocytes eventually results in liver fibrosis, followed by transformation into the so-called "cardiac cirrhosis".

The benefits of Pilates have been extensively researched for their impact on muscular, psychological, and cardiac health, as well as body composition, among other aspects. This study aims to investigate the influence of the Pilates method on the learning process, motor control, and neuromuscular trunk stabilization, specifically in both experienced and inexperienced practitioners. This semi-randomized controlled trial compares the level of experience among 36 Pilates practitioners in terms of motor control and learning of two Pilates-based skills: standing plank and side crisscross.

Abstract Background: The prognosis of liver iron overload is highly dependent on liver iron content (LIC) and the extent of liver fibrosis. Liver biopsy is the invasive reference method for fibrosis evaluation but with several limitations. Non-invasive biological methods (FibroTest, APRI) are not applicable in blood diseases. Transient elastography (TE) is a new non-invasive and rapid bedside method used to measure liver stiffness.This technique has been extensively studied with success in evaluation of liver fibrosis in HCV infection (Ziol, Hepatology 2005; Castera, Gastroenterology 2005).

Background. Hepatic fibrosis is a potential complication following Fontan surgery and heralds long-term risk for cirrhosis. Transient elastography (TE) is a rapid, noninvasive method to assess liver fibrosis by measuring liver stiffness.Objectives. To compare liver stiffness and liver biochemistries in pediatric Fontan patients with age- and sex-matched controls and to determine patients’ acceptance of TE.Methods. Patients were recruited from British Columbia Children’s Hospital. Twenty-two Fontan patients (15 males) were identified. Demographic information and cardiac data were collected. TE

Many heart diseases can change the elasticity of myocardial tissues, making elastography a potential medical imaging strategy for heart disease diagnosis and cardiovascular risk assessment. Among the existing elastography methods, ultrasound elastography is an appealing choice because of ultrasound’s inherent advantages of low cost, high safety, wide availability, and deep penetration. The existing investigations of cardiac ultrasound elastography were implemented based on a bulk model of heart tissue, treating the waves generated in the myocardial tissues as shear waves. In this pilot study,

Abstract Background Cardiac amyloidosis and Fabry disease are cardiomyopathies that evolve with structural alteration of the ventricular walls, diastolic dysfunction and heart failure. Diastolic dysfunction encompass myocardial stiffness and impaired relaxation. Cardiac elastography has been proposed as a diagnostic modality for the non-invasive assessment of myocardial stiffness. Purpose The aim of this study was to investigate if myocardial shear wave elastography could assess myocardial stiffness in Healthy volunteers, Fabry disease and variant transthyretin amyloidosis (ATTRv) patients wit
