Background: The pain sensation in a transperineal prostate biopsy was obvious. This study explored the clinical value of ultrasound-guided full-needle path anesthesia in transperineal prostate biopsy.
Methods: Two hundred patients who underwent ultrasound-guided transperineal prostate biopsy at our department were randomly divided into 2 groups.
Article Synopsis
- - This study assessed the effectiveness of MRI-guided contrast-enhanced ultrasound (CEUS) in diagnosing prostate cancer (PCa), analyzing data from 250 patients over two years.
- - Results showed that quantitative CEUS outperformed both qualitative CEUS and MRI in predicting PCa, with better AUC scores indicating its superior diagnostic ability.
- - The findings suggest that MRI-guided CEUS is a reliable and enhanced method for PCa diagnosis, and its characteristics could significantly improve the accuracy of detection.
Background & Aims: Initial screening for high-risk population of gastric cancer (GC) is needed in rural areas of large-population countries. This study aims to explore the feasibility of applying noninvasive ultrasonography as an initial screening strategy to improve the early diagnosis and prevention of GC.
Methods: Oral contrast-enhanced trans-abdominal ultrasonography (OCTU) was initially applied to screen around 15,000 residents from 24 different rural villages of Changxing Island in Shanghai, China, facilitating the identification of high-risk population for further endoscopy examination.

Background: This study aims to investigate the value of oral contrast ultrasonography (OCUS) in the diagnosis of gastric cancer in elderly patients.
Methods: OCUS data obtained from patients ≥ 60 years old were retrospectively analyzed and compared with gastroscopy results.
Results: Among the 12,716 subjects examined by OCUS, 5021 subjects were ≥ 60 years old, which accounted for 39.
Objective: To investigate the clinical value of contrast-enhanced ultrasonography (CEUS) in the diagnosis of prostate cancer in patients with different concentrations of prostate-specific antigen (PSA).
Methods: Based on the PSA concentration, 186 patients were divided into three groups (PSA 4－10 μg/L, 11－20 μg/L, and >20 μg/L) and underwent transrectal CEUS and biopsy. We compared the pathological results with the CEUS features in different groups of patients and performed a statistical analysis on the characteristics of the CEUS manifestations of prostate cancer and benign prostatic lesions.
Background: The present study is aimed at assessing the efficacy of oral contrast trans-abdominal ultrasonography (OCTU) as an initial screening tool for gastric cancer in rural areas of China.
Methods: All subjects that were enrolled from Chongming County, Shanghai, China. Subjects in the symptomatic group underwent both OCTU and gastroscopic biopsy.
[The value of high-frequency ultrasound in the diagnosis of duchenne muscular dystrophy in children].

Objective: To study the value of high-frequency ultrasound in the diagnosis of duchenne muscular dystrophy diseases (DMD) in children.
Methods: Eight children with DMD were enrolled as DMD group and 10 healthy children as the control group. The echogenicity of the rectus femoris muscle and the gap between the gastrocnemius and soleus muscles in the two groups were detected by high-frequency ultrasound.
