PURPOSE: To evaluate the feasibility of quantitative analysis of muscle stiffness in the medial gastrocnemius muscle (GCM) by acoustic radiation force impulse (ARFI) ultrasound elastography in children with spastic cerebral palsy (CP). METHODS: Seventeen children with spastic CP and 25 healthy children participated in the study between the years 2016-2017. The medial GCM in the CP group was assessed using the Modified Ashworth Scale (MAS) by a physiatrist. ARFI was used to measure the shear-wave velocities (SWVs) of the medial GCM...

PURPOSE: Chronic recurrent parotitis (CRP) is a non-obstructive disease with episodes characterized by painful swelling of the parotid gland. It presents in both a juvenile and an adult form, with no clear information on its actual origin. Diagnosis is based on patient medical history and ultrasound examination but is frequently not correctly identified. Acoustic Radiation Force Impulse Imaging (ARFI) is a novel ultrasound elastography technology that has recently been implemented in the diagnostic work-up of patients with malignancies...

Background Preterm birth is one of the important causes of neonatal morbidity where we rely on subjective criteria such as modified Bishop's scoring and contemporary sonographic measurement of cervical length. Acoustic radiation force impulse (ARFI) is a technological advancement in elastography that can be employed in prediction of cervical softening and preterm labor. Purpose To evaluate the role of ARFI technique and shear wave velocity (SWV) estimates as a predictor of preterm birth and its comparison with other clinical and sono-elastographic measures...

David Sherman, Phillip Lung, Philip Shorvon
Liver stiffness measurement (LSM) is the most widely used non-invasive alternative to biopsy for assessing liver fibrosis in the UK. Virtual touch quantification (VTq, also known as acoustic radiation force impulse) is the principal available alternative to transient elastography (Fibroscan) and is delivered via software enhancements to standard ultrasound (US) machines. It has recently been endorsed by National Institute for Health and Care Excellence in terms of both accuracy and cost-effectiveness for use in viral hepatitis...

To evaluate acoustic radiation force impulse (ARFI) inthe differential diagnosis of small (≤20 mm) solid breast lesions and identify the most efficient ARFI parameters. Conventional ultrasonography and ARFIwere performed in 120 patients with 121 small solid breast lesions. The area ratios (ARs) of the lesion on virtual touch tissue compared to B-mode were calculated. The shear wave velocity of the inner (SWVi) and boundary (SWVb) of the lesions and surrounding fatty tissue (SWVf) was measured. The ratio of SWVi to SWVf (SWVrat) was calculated...

BACKGROUND: acoustic radiation force impulse (ARFI) is a new proposed noninvasive method for liver fibrosis staging. Integrated with B-mode ultrasonography, ARFI can be used to assess liver tissue condition. However its diagnostic accuracy is still being continuously evaluated. Also, there is lack of data regarding the utilization of ARFI in our population. This study aimed to evaluate the diagnostic value of ARFI as an alternative noninvasive modality for fibrosis staging in chronic hepatitis B and hepatitis C patients in our population...

PURPOSE: We aimed to assess the improvement in stiffness in patients with postmastectomy lymphedema (PMLE) after intermittent pneumatic compression (IPC) using acoustic radiation force impulse (ARFI) imaging and evaluate the effects of different IPC pressures. METHODS: We randomly assigned 45 patients with PMLE (stage II) to three groups based on the IPC pressure: 25, 35, and 45 mmHg. Patients received a single session of IPC for 30 minutes. We recorded the subcutaneous tissue thickness of the proximal upper limbs using ultrasonography and circumference of the upper limbs and stiffness using ARFI before and immediately after IPC...

BACKGROUND: Spleen and liver stiffness measured by Acoustic radiation force impulse (ARFI) imaging has been showed to be useful in identifying patients with portal hypertension. AIM: to establish if the modification of portal pressure induced by a TIPS parallels the modification of spleen or liver stiffness measured by ARFI in order to understand if ARFI may be used to monitor the modification of portal pressure in patients with cirrhosis. PATIENTS AND METHODS: 38 patients with severe portal hypertension underwent liver stiffness (LS) and spleen stiffness (SS) before TIPS and one week after TIPS...

In previous studies of acoustic radiation force impulse (ARFI) elastography, using Virtual Touch tissue quantification (VTQ) (Siemens Acuson S2000), it was reported that the measurement of renal shear wave speed in patients with chronic kidney disease (CKD) is not influenced exclusively by renal fibrosis. The purpose of the present study was to analyze the role of VTQ in patients with diabetic kidney disease, considered the main cause of CKD. The study group included 164 patients: 80 patients with diabetic kidney disease (DKD) and 84 without renal disease or diabetes mellitus...

OBJECTIVES: Liver fibrosis (LF) is crucial for the individualized management of patients with hepatitis C virus (HCV). We evaluated the concordance between two noninvasive methods for staging LF, transient elastography (TE) and acoustic radiation force impulse (ARFI), in patients coinfected with human immunodeficiency virus and HCV. We propose an algorithm for optimal use of both techniques in routine clinical practice. METHODS: A total of 89 human immunodeficiency virus/HCV-coinfected patients underwent TE and ARFI on the same day...
