Hua Xin, Jie Li, Hai-Yang Hu
BACKGROUND: Childhood mortality due to pneumonia is high. Chest radiography is the primary imaging modality used for the evaluation of pneumonia in children. Lung ultrasonography (LUS) is a newer, alternative diagnostic method that has been gaining popularity in recent years. We conducted a meta-analysis to summarize the diagnostic usefulness of LUS for childhood pneumonia. METHODS: All studies included in this meta-analysis were retrieved from PubMed, Elsevier's Science Direct, and Springer, and by manual searches including the use of reference lists, through March 31, 2017...

The aim of this pictorial review is to describe the technical advances achieved through the application of 4-dimensional (4D) ultrasound using spatiotemporal image correlation (STIC) over conventional 2-dimensional ultrasound in the prenatal detection of congenital heart disease (CHD). Spatiotemporal image correlation is a volume imaging technique that simplifies fetal heart studies while providing more diagnostic information than is typically available from traditional 2-dimensional studies. Four-dimensional software allows the study of cardiac anatomy and function during a single cardiac cycle and has greatly contributed to diagnostic enhancement of CHD...

This study was to evaluate the correlation between birth weight and the distance between distal rectal pouch and perineum (P-P distance) and to determine a cutoff value for P-P distance to diagnose low-type imperforate anus in neonates with low-birth weight (LBW).We included 15 neonates with LBW (mean weight, 2012 ± 470 g; range, 906-2452 g) and imperforate anus (surgically confirmed: 11 low type and 3/1 intermediate/high type), who underwent ultrasonography on the day after birth. Type of imperforate anus was defined based on the International Classification of Anorectal Anomalies...

OBJECTIVE: This study aimed to evaluate the ultrasonographic pattern of cervical lymph nodes (CLNs) and whether levothyroxine with prednisone therapy is effective for lymphadenopathy in patients with Hashimoto thyroiditis (HT). METHODS: This retrospective study was looking at patients with confirmed diagnosis of HT who underwent comprehensive neck ultrasound examination. We reviewed sonographic findings in 127 patients with HT, 234 euthyroid patients with goiter, and 122 healthy subjects...

OBJECTIVE: The aims of this study are to evaluate the utility of sonoelastography for parotid gland masses and to determine which cutoff strain ratio (SR) would be best for the differentiation between benign and malignant lesions. METHODS: From August 2015 to December 2016, 39 parotid gland masses were examined prospectively by ultrasonography and strain sonoelastography. Elastographic scores were determined by a 4-point scoring method. Interventional procedures were performed on all patients after sonographic examinations...

The purpose of our study was to determine if a textural analysis metric can be implemented to improve diagnosis of adenomyosis by ultrasound.We retrospectively identified 38 patients with a magnetic resonance imaging (MRI) diagnosis of uterine adenomyosis that also had a pelvic ultrasound within 6 months. We also identified 50 normal pelvic ultrasound examinations confirmed by a normal pelvic MRI within 6 months as a control group. A region of interest (ROI) was subsequently placed on the study population ultrasound image corresponding to the area of adenomyosis on MRI...

Abdominal ultrasound of a 28-year-old man with chronic abdominal pain and vomiting demonstrates a dilated aperistaltic distal esophagus, which was confirmed on follow-up esophagram as achalasia. The 2 main types of achalasia are primary and secondary. Primary achalasia occurs with the loss of postganglionic neurons resulting in failed distal esophageal relaxation. Secondary achalasia is esophageal narrowing due to nondenervation causes. The diagnosis of achalasia is typically made with manometry and barium esophagram...

Risks associated with isolated great saphenous vein (GSV) thrombosis remain controversial. The purpose of this study is to identify the risk of pulmonary embolism (PE) in patients with isolated GSV thrombosis, particularly those with thrombus within 3 cm of the sapheno-femoral junction. A retrospective chart review of color flow Doppler lower extremity venous ultrasound examinations from an academic hospital from 2011 to 2016 was conducted. Seventy-eight patients were identified as having acute thrombus in their GSV and were then further stratified based on the presence or absence of concomitant deep venous thrombosis (DVT)...

Training adult learners to use ultrasound in clinical practice relies on the ability of the learner to apply visuospatial concepts to the anatomy of the human body. We describe a visuospatial trainer that replicates the housing of an ultrasound transducer, through which a linear laser projects light in the same plane and orientation as the ultrasonic sound waves. We use this trainer in combination with a porcine heart dissection laboratory to teach bedside cardiac ultrasound and transthoracic echocardiography (TTE)...

Qiuyue Chen, Shilin Li, Guorong Lv, Yanchun Zhao
To assess the role of ultrasonography for assessing middle cerebral arteries (MCAs) in rheumatoid arthritis (RA). Middle cerebral arteries of 32 RA patients and 32 healthy volunteers were examined by ultrasonography. Peak systolic blood flow velocity (PSV), end-diastolic velocity, and resistance index (RI) of MCA were measured using Doppler ultrasound. Results were expressed as mean ± SD. No significant difference in peak systolic velocity was obtained between RA patients (52.44 ± 19.56 cm/s) and healthy volunteers (51...

This study aimed to investigate the usefulness of a thyroid imaging reporting and data system (TIRADS) to select thyroid nodules with atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) cytology for additional BRAF mutation testing. Three hundred three thyroid nodules were included. Statistical analysis was performed at both patient and nodule levels according to BRAF mutation positivity and clinical factors. Univariate and multivariate logistic regression analyses were performed to assess independent associations between BRAF mutation positivity and clinical factors...

This study aimed to evaluate the advantages of routine ultrasound (US), contrast-enhanced US (CEUS), and the combination of these 2 methods in diagnosing papillary thyroid carcinoma (PTC). We subjected 89 patients with calcified thyroid nodules to conventional US and CEUS and then retrospectively analyzed the US and CEUS features of 89 patients with single, solid PTC. On this basis, we then evaluated the ability of US, CEUS, and their combination to diagnose PTC. In the 89 patients with thyroid nodules, US findings differed significantly from CEUS findings (P < 0...

Early and accurate prenatal diagnosis of intrauterine growth restriction is important. Commonly used biometric parameters have limited specificity and require accurate dating. Fetal abdominal wall thickness (AWT) could be a useful supplemental parameter. We performed a retrospective study of 100 third trimester ultrasound exams and compared the sensitivity and specificity of AWT to those of weight percentile (WP) in predicting adverse perinatal outcome.There is a statistically significant difference between the AWT of patients with normal perinatal outcome and that of patients with adverse outcome (P < 0...
