Amongst the newer predictors, acoustic radiation force impulse-virtual touch tissue quantification values of liver and spleen has certain predictive value for esophageal varices and it might be useful for primary screening of esophageal varices in post-hepatitis B cirrhosis patients20.
Renal elasticity quantifcation by acoustic radiation force impulse applied to the evaluation of kidney diseases: a review.
The articles by Akdogan E and Gelebek Yilmaz F entitled "The role of acoustic radiation force impulse elastography in the differentiation of benign and malignant focal liver masses" (Turk J Gastroenterol 2018; 29: 456-63) and Comba et al entitled "Prevalence of celiac disease among school-age children in Corum, Turkey" (Tur J Gastroenterol 2018; 29: 596-600) were published erronously with wrong DOIs.
In the acoustic radiation force impulse (ARFI) elastography technique, the shear waves that stimulate the target tissue are generated within a fixed-size ROI placed on an operator-selected conventional grayscale US image (34).
Doppler, ARFI (acoustic radiation force impulse) elastography and contrast-enhanced ultrasonography are non-invasive using novel ultrasonography-based imaging modalities can also contribute to testicles evaluation in animals (7-8).
Static ultrasound elastography includes strain imaging, while dynamic ultrasound elastography is divided into shear wave and acoustic radiation force impulse imaging (Figure 1).
Objective: To investigate the value of Acoustic Radiation Force Impulse elastography and its application in Achilles tendon elasticity of intermittent claudication due to lower extremity arterial ischaemia.
In efforts to increase objectivity and reproducibility, the acoustic radiation force impulse (ARFI) technique was developed, which involves emitting acoustic pulses inside tissue to generate micron-scale displacement.
The most promising seems to be a simple score derived from the combination of acoustic radiation force impulse (ARFI) velocity and spleen diameter/platelet count [63].
The 'Virtual Touch Tissue Quantification[TM]' method based on the non-invasive 'acoustic radiation force imaging' method was used with the 9-4 MHz linear array probe.
Further advances in technology has led to totally noncontact excitations and measurements using ultrasound radiation force such as those used by Huber et al.
Vertical distribution of aerosols has a great impact on the heating rate profile, which provides more details about dust aerosol DRE on different atmospheric levels than radiation force. Over the Taklimakan Desert, dust aerosols can heat the atmosphere by up to 1, 2, and 3K [d.sup.-1] (daily mean values) under light, moderate, and heavy dust conditions, respectively; the maximum daily mean of radiative heating rate can reach 5.5 K [d.sup.-1] at 5 km, at the location of the dust layer [34].
