Ultrasound Elastography in the Differentiation of Simple Cyst and Type I Hydatid Cyst of the Liver
Hydatid cyst (HC) is a parasitic disease that is endemic particularly to the sheep-breeding regions of the world, our country included. Given their propensity to materialize most commonly in the liver, our study evaluates the value of ultrasound elastography in the differential diagnosis of simple cyst and type I HCs of the liver.

Comparison of Sound Touch Elastography, Sound Touch Quantify, and 4 Serum Fibrosis Indexes for the Diagnosis of Liver Fibrosis in Patients With Chronic Hepatitis B
The aim of this research was to compare the use of shear wave elastography (sound touch elastography [STE] and sound touch quantify [STQ]) and serum liver fibrosis indexes in the evaluation and staging of chronic hepatitis B (CHB) liver fibrosis. Sound touch elastography is a form of 2-dimensional shear wave elastography, and STQ is a form of point shear wave elastography. Between June 2018 and March 2019, 122 patients with CHB were assessed using STE and STQ. Serum liver biomarkers tests were undertaken, and liver biopsy was performed, and these were used to assign a pathological stage based on the Scheuer scoring system....

Liver Stiffness Detected by Shear Wave Elastography Predicts Esophageal Varices in Cirrhotic Patients
Ultrasound elastography has become a promising noninvasive approach for assessing liver fibrosis. The purpose of this study was to evaluate the diagnosis ability of liver stiffness detected by shear wave elastography (SWE) for predicting the presence of esophageal varices (EVs) in cirrhotic patients. Four hundred sixty-eight cirrhotic patients were enrolled consecutively. Liver stiffness and EVs were detected by SWE and endoscopy, respectively. The baseline characteristics were recorded, and areas under the receiver operating characteristic curves (AUROCs) were used to compare the diagnosis accuracy. Multivariate analysis ...

Diagnostic Performance of Shear Wave Elastography in the Noninvasive Evaluation of Liver Inflammation of Chronic Hepatitis B Patients
In the current study, we sought to delineate the elastographic characteristics and further compare the diagnostic performance of various shear wave elastography modalities in hepatitis B virus patients whose liver fibrosis stage was less than F2 by liver biopsy. We retrospectively studied the clinical and imaging data of chronic hepatitis B virus patients who underwent liver biopsy at our hospital between January 2017 and October 2017. Totally, 102 patients were eligible for the study. The mean Young modulus of sound touch elastography (STE) and sound touch quantify (STQ) gradually increased as inflammation grade of the li...

A New Visual Transient Elastography Technique for Grading Liver Fibrosis in Patients With Chronic Hepatitis B
This study enrolled 227 patients (79 [39.1%] women; mean age, 45.8 ± 16.8 years). The ViTE and FS liver elasticity measurements were highly correlated with liver fibrosis stage (r = 0.852 and r = 0.813, respectively). The area under the receiver operating characteristic curve value was larger for ViTE compared with FS, with respect to differentiating liver fibrosis stage, but not significantly (P> 0.05). The ViTE and FS can be used to detect and stage liver fibrosis. ViTE, easier and quicker to perform with superior interoperator reproducibility, is a stable and reliable elastography technique that benefits from real-time...

The Performance of a 2-Dimensional Shear-Wave Elastography Technique for Predicting Different Stages of Liver Fibrosis Using Transient Elastography as the Control Method
The aim was to evaluate the performance of 2-dimensional (2D) shear-wave elastography from general electric (2D SWE-GE), implemented on the new LOGIQ S8 system, for the noninvasive assessment of liver fibrosis, and to identify liver stiffness (LS) cutoff values for predicting different stages of fibrosis using transient elastography (TE) as the control method. We included 179 consecutive subjects, with or without chronic hepatopathies, in whom LS was evaluated in the same session using 2 elastographic techniques: TE (FibroScan, EchoSens) and 2D SWE-GE (LOGIQ S8; GE Healthcare, Chalfont St Giles, United Kingdom). Reliable L...

Quantitative Ultrasound Elastography Methods in Focal Liver Lesions Including Hepatocellular Carcinoma: From Diagnosis to Prognosis
The ability of ultrasound elastography to diagnose focal liver lesions and determine their prognoses including hepatocellular carcinoma (HCC) is unclear. At present, radiofrequency ablation and liver resection are the most common treatments for HCC. However, the survival rate remains disappointing because of recurrences and postoperative liver failure, necessitating the development of noninvasive approaches. There is currently no systematic definition of an elastic technique for measuring liver stiffness to predict the recurrence of HCC after radiofrequency ablation and postoperative liver failure. In this review, recent a...

Images in Scalp Ultrasound Before and After Hair Transplant in Frontal Fibrosing Alopecia
Primary cicatricial alopecias are inflammatory scalp conditions that may lead to permanent hair loss and severe alopecia. Frontal fibrosing alopecia is one of the most frequent etiologies of primary cicatricial alopecias. Hair transplant could be a therapeutic option. (Source: Ultrasound Quarterly)

In Vivo Flattening of the Central Aponeurosis of the Rectus Femoris Due to Knee Extension Torque in Healthy Young and Elderly Individuals With Knee Osteoarthritis
We aimed to elucidate the relationship between active force production and the curvature of the central aponeurosis (CA) of the rectus femoris in young healthy participants as fundamental data and compare the muscle CA curvature before and after straight leg raising (SLR) training in participants with knee osteoarthritis (OA). Central aponeurosis curvature was determined during submaximal and maximal voluntary contractions (MVCs) using ultrasonography. Twenty-five young healthy female volunteers underwent ultrasonographic measurements under conditions of isometric MVC. They were divided into a flat shaped CA group (flat) a...

Reliability of Real-Time Sonoelastography in the Diagnosis of Supraspinatus Tendinopathy
The practicality of real-time sonoelastography in the diagnosis of tendinopathy is being discussed since the beginning of its use in musculoskeletal system. The aims of this study were to compare the elasticity of pathologic supraspinatus tendon with the uninvolved side by sonoelastography and to determine the relationship between the sonoelastographic findings and magnetic resonance imaging (MRI) grade of the tendinosis. Eighty-2 patients (50 males, 32 females, mean ± SD age = 53.61 ± 16.15 years, range = 20–84 years) with unilateral supraspinatus tendinosis were included in this study. Three grades of tendinosis were...

Quantitative Assessment of Muscular Stiffness in Children With Chronic Kidney Disease Using Acoustic Radiation Force Impulse Ultrasound Elastography
The aim of this study was to evaluate the feasibility of quantitative analysis of muscle stiffness in the rectus femoris muscle (RFM) by acoustic radiation force impulse (ARFI) ultrasound elastography in children with chronic kidney disease (CKD). Twenty-three children with CKD and 22 healthy children participated in the study in our radiology department. The strength of each CKD group and healthy group participants' tight extensors was assessed by a physiatrist using a handheld dynamometer. Acoustic radiation force impulse was used to measure the shear wave velocities (SWVs) of the RFM. The mean SWV value of the RFM corre...

Superb Microvascular Imaging in Assessment of Synovitis and Tenosynovitis in Juvenile Idiopathic Arthritis
The aim of this study is to evaluate the diagnostic utility of superb microvascular imaging (SMI) in assessment of synovitis/tenosynovitis in juvenile idiopathic arthritis in comparison to power Doppler ultrasound. Thirty juvenile idiopathic arthritis cases with active clinical findings and ultrasound features of effusion and/or tenosynovitis were further imaged with power Doppler and SMI. For classification of synovial inflammation, a semiquantitative scale (4 points) adopted by Outcome Measures in Rheumatology was used. (Source: Ultrasound Quarterly)

Imaging Findings of Mammary Myofibroblastoma: A Rare Fat-Containing Entity
Mammary myofibroblastoma (MFB) is a rare benign stromal neoplasm; its imaging features are rarely reported and nonspecific. We retrospectively analyzed a case of pathologically proved breast MFB that revealed indistinct high-density mass in mammography and hypoechoic ill-defined breast tumor in ultrasonography. Meanwhile, hypointense appearance on T2-weighted imaging of magnetic resonance imaging and containing fat tissue might be very valuable characteristics in the differential diagnosis of breast MFB.
