Avoidant/restrictive food intake disorder (ARFID) is a feeding or eating disorder in which individuals significantly limit the volume or variety of foods they consume, causing malnutrition, weight loss, or psychosocial problems. [1] Unlike eating disorders such as anorexia nervosa and bulimia, body image disturbance is not a root cause. [1] [2] Individuals with ARFID may have trouble eating ...

2021年6月8日 · Learn about everything from symptoms to treatment for avoidant restrictive food intake disorder (ARFID).

Acoustic radiation force impulse (ARFI) imaging is a new and promising ultrasound-based diagnostic technique that, evaluating the wave propagation speed, allows the assessment of the tissue stiffness. ARFI is implemented in the ultrasound scanner. ...

2021年11月12日 · ARFI images are formed using commercial diagnostic ultrasound scanners to both generate localized, impulsive acoustic radiation forces in tissues, and to monitor the transient, dynamic displacement tissue response within the …

ARFI is a non-invasive alternative to a liver biopsy for the evaluation of Liver fibrosis. A liver biopsy is still recommended as the gold standard method for determining the fibrosis stage, the prognosis and the therapeutic indications in patients with chronic liver disease.

2011年11月1日 · ARFI images have spatial resolution comparable to that of B-mode, often with greater contrast, providing matched, adjunctive information. SWEI images provide quantitative information about the tissue stiffness, typically with lower spatial resolution.

2016年8月23日 · This review targets the clinical applications of ARFI in the evaluation of chronic diffuse disease, especially of liver and kidneys. The contribution of ARFI to the clinical workout of these patients and some possible perspectives are described.

Acoustic Radiation Force Impulse (ARFI) imaging is a new method for quantifying mechanical properties of tissue, without manual compression, by measuring the shear wave velocity induced by acoiustic radiation and propagating in the tissue.

Background: Acoustic radiation force impulse (ARFI) elastometry quantifies hepatic stiffness, and thus degree of fibrosis, non-invasively. Our aim was to analyse the diagnostic accuracy of ARFI cut-off values, and the significance of a defined limit of standard deviation (SD) as a potential quality parameter for liver fibrosis staging in ...

The main goal of the Atlantic Rainforest Institution (ARFI) is to preserve and reforest the critically endangered Atlantic Rainforest in Southern Bahia, Brazil. Alarmingly, 93% of its original size has been lost.
