Ultrasound-Guided Percutaneous Needle Biopsy for Peripheral Pulmonary Lesions: Diagnostic Accuracy and Influencing Factors.

A retrospective study was carried out to evaluate the diagnostic accuracy and the factors influencing the diagnostic accuracy of 648 procedures of ultrasound-guided percutaneous needle biopsy (PNB) for peripheral pulmonary lesions (PPLs). We reviewed the histopathology results, the clinical records and the procedure reports of these 648 biopsies and the final diagnoses of 637 PPLs to determine the diagnostic accuracy of ultrasound-guided PNB. Factors that influenced the diagnostic accuracy were assessed by analysis of the biopsy procedures, which were classified as diagnostic cases (true-positive and true-negative) and non-diagnostic cases (false-positive, false-negative and indeterminate).

Prostate ultrasound imaging: evaluation of a two-step scoring system in the diagnosis of prostate cancer.

Rationale And Objectives: This study aims to investigate the feasibility and performance of a two-step scoring system of ultrasound imaging in the diagnosis of prostate cancer.

Material And Methods: 75 patients with 888 consecutive histopathologically verified lesions were included in this study. Step 1, an initial 5-point scoring system was developed based on conventional transrectal ultrasound (TRUS).

Differential diagnostic performance of acoustic radiation force impulse imaging in small (≤20 mm) breast cancers: Is it valuable?

To evaluate acoustic radiation force impulse (ARFI) inthe differential diagnosis of small (≤20 mm) solid breast lesions and identify the most efficient ARFI parameters. Conventional ultrasonography and ARFIwere performed in 120 patients with 121 small solid breast lesions. The area ratios (ARs) of the lesion on virtual touch tissue compared to B-mode were calculated.

Different extent of hypoxic-ischemic brain damage in newborn rats: histopathology, hemodynamic, virtual touch tissue quantification and neurobehavioral observation.

Objective: To explore the correlation between pathological and ultrasound changes applying conventional ultrasound, Color Doppler ultrasound andVirtual Touch Tissue Quantification (VTQ) technique in newborn hypoxic-ischemic brain damage (HIBD) rat models. To provide theoretical basis for early diagnosis and treatment of HIBD neonatal.

Methods: A total of 90 newborn Wistar rats were divided into ischemia, asphyxia and control group according to different HIBD molding methods.

Application of ultrasound imaging of upper lip orbicularis oris muscle.

In this study, we aim to understand the morphology and structure of upper lip orbicularis oris muscle, and to provide clinical evidence for evaluating the effect of repair operation in cleft lip. Subjects included 106 healthy people and 36 postoperative patients of unilateral cleft lip. The upper lip orbicularis oris muscle was scanned using ultrasound in natural closure and pout states.

Association of maternal education with the neuroblastoma susceptibility in children: a meta-analysis.

Maternal education might be an important factor for the neuroblastoma risk in children, but it was conflicting. This meta-analysis was performed to evaluate the relationship between maternal education and neuroblastoma susceptibility and to explore whether maternal education was an important indicator to be associated with the neuroblastoma risk in children. The association studies were identified from the databases of PubMed, and Cochrane Library as of June 1, 2012, and eligible investigations were synthesized using meta-analysis method.

Sonographic demonstration of the normal thoracic esophagus.

Purpose: Although conventional sonography has been used widely in evaluation of the abdominal and cervical esophagus, its use in the thoracic esophagus is seldom mentioned. The aim of this study was to assess whether conventional sonography could demonstrate the thoracic esophagus and to determine this structure's normal sonographic appearance and measurements.

Methods: Transthoracic sonography was performed in 253 healthy volunteers ranging in age from 12 to 72 years (mean, 41 +/- 15 years).

Sonographic anatomy of the cervical esophagus.

Purpose: Although conventional sonography is used widely for evaluation of the gastroesophageal junction, its use in the cervical esophagus is still limited. The aim of this study was to assess the use of sonography to demonstrate this portion of the esophagus.

Methods: The cervical esophagi in 60 cadavers and 435 healthy volunteers were examined sonographically.
