Clinical value of ultrasound-guided full-needle path anesthesia in transperineal prostate biopsy: An observational study.

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.

Comparison of contrast-enhanced ultrasound targeted biopsies versus standard systematic biopsies for prostate cancer correction in different PSA value groups in rural China.

Objective: To investigate prostate cancer detection rate of different biopsy protocols in different PSA value groups in rural China.

Methods: A total of 186 patients underwent contrast-enhanced ultrasound (CEUS) in order to determine the puncture target prior to biopsy were enrolled in this retrospective study. All patients underwent 12-core SB combined with CEUS-TB.

The value of oral contrast ultrasonography in the diagnosis of gastric cancer in elderly patients.

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.

[Clinical value of contrast-enhanced ultrasonography in the diagnosis of prostate cancer in patients with different PSA concentrations].

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.

[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.
