Case report: Uncommon manifestations of Rosai-Dorfman disease in the liver mimicking HCC.

Rosai-Dorfman-Destombes disease (RDD) is a rare non-Langerhans cell histiocytosis (LCH) disorder characterized by systemic extranodal lesions. Common cases include skin lesions, whereas liver lesions are rare. This study presents a case of a 66-year-old woman with a solitary extranodal liver lesion who underwent successful surgical treatment followed by glucocorticoid therapy.

Stiffness of prostate gland measured by transrectal real-time shear wave elastography for detection of prostate cancer: a feasibility study.

Objective: This study aimed to evaluate the value of the Young's modulus obtained by transrectal real-time shear wave elastography (SWE) for detection of prostate cancer (PCa).

Methods: 215 patients underwent SWE in six identical planes before biopsy guided with transrectal ultrasonography. The Young's modulus of the entire prostate gland was defined as the mean of the results in these planes.

Comparison of Two-Dimensional Shear Wave Elastography with Nine Serum Fibrosis Indices to Assess Liver Fibrosis in Patients with Chronic Hepatitis B: A Prospective Cohort Study.

Purpose:  To prospectively assess liver fibrosis with two-dimensional shear wave elastography (2D-SWE) in patients with chronic hepatitis B (CHB) and to compare the performance of this modality with that of serum indices using Scheuer scoring from liver biopsies as the reference standard.

Materials And Methods:  123 patients with CHB underwent 2D-SWE measurements and serological tests between April 2016 and February 2018. The 2D-SWE and serum indices in the diagnosis of liver fibrosis were assessed using receiver operating characteristic (ROC) analyses.

The value of shear wave elastography in diffuse thyroid disease.

Purpose: The aim of this study is to discuss the value of ultrasound-based shear wave™ elastography (SWE) in diffuse thyroid disease (DTD).

Method: Thyroid stiffness in 154 patients with DTD and 30 normal subjects was measured by SWE. The serum indicators of all subjects were detected.

Acoustic Structure Quantification Versus Point Shear Wave Speed Measurement for the Assessment of Liver Fibrosis in Viral Hepatitis B.

This study was conducted to evaluate the value of acoustic structure quantification (ASQ) technology versus that of point shear wave speed measurement (PSWSM) imaging technology for the assessment of liver fibrosis stage. A total of 104 patients with chronic hepatitis B (CHB) and 30 healthy control patients underwent ASQ and PSWSM examinations. Seven quantitative parameters were obtained from ASQ, and a principal component analysis was used to establish the integrative indicators.
