Associations Between Multiparametric US-Based Indicators and Pathological Status in Patients with Metabolic Associated Fatty Liver Disease.

Objective: Noninvasive evaluation of metabolic dysfunction-associated fatty liver disease (MAFLD) using ultrasonography holds significant clinical value. The associations between ultrasound (US)-based parameters and the pathological spectra remain unclear and controversial. This study aims to investigate the associations thoroughly.

Dynamic contrast-enhanced ultrasound characteristics of renal tumors: VueBox™ quantitative analysis.

Background: VueBoxtrademark has been used for contrast analysis in DCE-US-based quantitative research.

Objective: Aim of this study was to use the enhancement-mode and VueBoxtrademark parameters to further evaluate the differential diagnostic value of DCE-US for renal tumors.

Methods: 24 patients with renal tumors, including 7 benign and 17 malignant, were retrospectively analyzed.

Case report: Anti-CNTN1 antibody-associated nodopathies disease with asymmetric onset.

Anti-contactin-1 (CNTN1) IgG4 antibody-associated nodopathies is an autoimmune antibody-mediated peripheral neuropathy with a unique clinical presentation, pathophysiology, electrophysiology, and therapeutic response. The critical histopathological features are a dense lymphoplasmacytic infiltrate, a storiform pattern of fibrosis, and obliterative phlebitis. Here, a 62-year-old male patient presented with subacute unilateral limb onset, progressive exacerbation, marked weakness of the extremities, cranial, and autonomic nerve involvement.

Characteristics of contrast-enhanced ultrasound for diagnosis of solid clear cell renal cell carcinomas ≤4 cm: A meta-analysis.

Now solid renal tumors ≤4 cm is the most common, especially the subtype of clear cell renal cell carcinoma (ccRCC) of malignant kidney tumors in clinical. However, there is not specific characteristics of contrast-enhanced ultrasound (CEUS) be recommended by the EFSUMB Guidelines in distinguish the essence of the kidney tumor with different sizes. Therefore, this meta-analysis aimed to assess the ability of CEUS to diagnose solid ccRCC (sccRCC) ≤4 cm.

The correlation between calcification in carotid plaque and stroke: calcification may be a risk factor for stroke.

Background: There are few studies on the relationship between calcified plaques and stroke by ultrasound. We investigated the association between calcification in carotid plaque and stroke by analyzing the different characteristics of calcification and neovascularization distribution in heterogeneous plaques by both two-dimensional and contrast-enhanced ultrasound (CEUS).

Methods: A total of 69 patients who were about to undergo carotid endarterectomy were selected between January 2016 and December 2017.
