The aim of this study was to investigate ultrasound time-harmonic elastography for quantifying aortic stiffness in vivo in the context of aging and arterial hypertension.
This article was published in the following journal.
Name: Investigative radiology
Ultrasound elastography is an emerging imaging technique that provides an objective method to assess the relative or absolute stiffness of soft tissues. The authors have not found any description in t...
The arterial input function (AIF)-time-density curve (TDC) of contrast at the coronary ostia-plays a central role in contrast enhanced computed tomography angiography (CTA). This study employs computa...
Background Glomerulonephritis refers to renal diseases characterized by glomerular and tubulointerstitial fibrosis. Multifrequency US time-harmonic elastography enables the noninvasive quantification ...
Dynamic compliance (Cd) of the adult thoracic ascending and arch aorta has had limited evaluation in vivo in patients with aortic disease. This study evaluates aortic compliance using intravascular ul...
Large aortic diameter is considered the most frequent cause of aortic dissection. However, this assumption relies on postdissection imaging of the aorta. We recently showed that acute dissection leads...
Abnormalities of the aorta have been identified in patients who have undergone repair of coarctation of the aorta by various surgical techniques. These abnormalities are thought to contri...
Evaluation of Aortic Stiffness as a Prognostic Indicator of Aortic Dilatation in Patients With Bicuspid Aortic Valve (BAV) by Multimodal Imaging (MRI, Echocardiography and Ultrafast Ultrasound Imaging)
The objective is the development and validation of morphological markers informative of aortic dilatation in order to improve the precision of the risk of aneurysm of the thoracic aorta an...
Tissue elasticity is being increasingly used as diagnostic parameter, since at the macroscopic level benign breast lesions tend to be stiffer than normal breast tissue but softer than brea...
The aim of our study was to evaluate the impact of aortic root replacement by a graft on the elastic properties of the descending thoracic aorta using cardiac Magnetic Resonance Imaging (M...
Abdominal aortic aneurysm (AAA) disease is an abnormal bulging of the main abdominal artery, which is the called the abdominal aorta. The purpose of this observational study is to identify...
An abnormal balloon- or sac-like dilatation in the wall of the THORACIC AORTA. This proximal descending portion of aorta gives rise to the visceral and the parietal branches above the aortic hiatus at the diaphragm.
A birth defect characterized by the narrowing of the AORTA that can be of varying degree and at any point from the transverse arch to the iliac bifurcation. Aortic coarctation causes arterial HYPERTENSION before the point of narrowing and arterial HYPOTENSION beyond the narrowed portion.
Small clusters of chemoreceptive and supporting cells located near the ARCH OF THE AORTA; the PULMONARY ARTERIES; and the coronary arteries. The aortic bodies sense PH; CARBON DIOXIDE; and oxygen concentrations in the BLOOD and participate in the control of RESPIRATION. The aortic bodies should not be confused with the PARA-AORTIC BODIES in the abdomen (which are sometimes also called aortic bodies).
Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).
The downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE causing misalignment of the cusps. Severe valve distortion can cause leakage and allow the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to aortic regurgitation.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
Cardiology is a specialty of internal medicine. Cardiac electrophysiology : Study of the electrical properties and conduction diseases of the heart. Echocardiography : The use of ultrasound to study the mechanical function/physics of the h...
Pulmonary arterial hypertension (PAH) is a chronic, life-threatening disorder characterized by abnormally high blood pressure in the arteries between the heart and lungs of affected individuals. Symptoms can range from mild breathles...
