OBJECTIVES: There is conflicting information regarding the role of nuchal septations during first-trimester genetic screening. This study was designed to determine whether nuchal septations are risk factors for chromosomal anomalies, independent of increased nuchal translucency (NT), in the first trimester of pregnancy. METHODS: This retrospective cohort study included all women who underwent first-trimester genetic screening between November 2011 and December 2014...

OBJECTIVES: To evaluate dynamic 2-dimensional (2D) transperineal pelvic sonographic findings and urodynamic studies in women with lower urinary tract symptoms after midurethral sling placement. METHODS: Transperineal pelvic sonography and urodynamic studies were reviewed from women with a midurethral sling and lower urinary tract symptoms. The shape and sonographic dynamic change of the sling from the rest position to the maximum Valsalva maneuver and back to rest were recorded...

Wound healing may be a difficult problem, and variable types of artificial skin prototypes have been developed for supporting this process. Using ultrasound, we studied 4 cellulose-derived artificial skin prototypes and assessed their two-dimensional and three-dimensional morphology. These prototypes were identified on ultrasound both on in vitro and in vivo studies. They allowed the sonographic observation of deeper layers on different types of surfaces of the body with good definition on the in vivo examinations performed on healthy skin and cutaneous ulcers...

OBJECTIVES: Recent research provides evidence that anogenital distance may serve as a novel metric to assess reproductive potential in men. In children, a shorter anogenital distance was linked with cryptorchidism, hypospadias, and micropenis. Scarce data exist in the literature regarding anogenital distance measurement in the fetus. The aim of our study was to assess whether intrauterine measurement of fetal anogenital distance could assist in the differential diagnosis of male genital anomalies...

OBJECTIVES: To determine whether a complete abdominal sonographic examination is necessary in the evaluation of children with right lower quadrant pain that is suspicious for appendicitis in the emergency department and whether performing a limited, more-focused study would miss clinically important disease. METHODS: With Institutional Review Board approval, a retrospective study was performed of 704 patients, from ages 5-19 years, presenting to the emergency department with right lower quadrant pain that was suspicious for appendicitis who underwent a complete abdominal sonographic examination...

OBJECTIVES: The aim of the study was to explore whether learning curves on a virtual-reality (VR) sonographic simulator can be used to predict subsequent learning curves on a physical mannequin and learning curves during clinical training. METHODS: Twenty midwives completed a simulation-based training program in transvaginal sonography. The training was conducted on a VR simulator as well as on a physical mannequin. A subgroup of 6 participants underwent subsequent clinical training...

OBJECTIVES: Intrathyroid metastases from extrathyroid primary tumors are rare. Clinical findings may be subtle, but detection of intrathyroid metastases has improved with sonography. The objective of this study was to evaluate the sonographic appearance of intrathyroid metastases. METHODS: Patients with thyroid masses with cytopathologic features matching those of an extrathyroid primary tumor were retrospectively identified. The appearances of intrathyroid metastases on sonography were reviewed for the following features: size, margin regularity, echogenicity, echotexture, vascularity on power or color Doppler ultrasonography, and the presence or absence of any associated cervical adenopathy...

OBJECTIVES: We sought to determine the performance of real-time sonoelastography in the differential diagnosis of parotid gland tumors. METHODS: Between April, 2014, and June, 2015, 54 parotid gland masses were examined by ultrasound and strain sonoelastography in 46 patients. Real-time sonoelastography using the elasticity score (E-index), which gives an absolute value between 0 (softest) and 6 (hardest), was performed. Demographic characteristics, histopathologic examination, and difference in elasticity scores between benign and malignant masses were evaluated...

BACKGROUND: Giant cell arteritis (GCA) is a relatively common form of primary systemic vasculitis, which, if left untreated, can lead to permanent sight loss. We compared ultrasound as an alternative diagnostic test with temporal artery biopsy, which may be negative in 9-61% of true cases. OBJECTIVE: To compare the clinical effectiveness and cost-effectiveness of ultrasound with biopsy in diagnosing patients with suspected GCA. DESIGN: Prospective multicentre cohort study...

Predictive markers of failure of induction of labour in term pregnancy were evaluated. A prospective study including 245 women attending induction of labour was performed. The inclusion criteria were singleton pregnancies, gestational age 37-42 weeks and the main outcomes were failure of induction, induction to delivery interval and mode of delivery. Women with a longer cervical length prior to induction (CLpi) had a higher rate of failure of induction (30.9 ± 6.8 vs. 23.9 ± 9.3, p < .001)...

The purpose of this study was to assess the differences in clinical and sonographic features of papillary thyroid carcinoma (PTC) between cervical lymph node metastatic (CLNM) and nonmetastatic groups. Clinical data of PTC patients (414 patients with 624 malignant nodules) who underwent a preoperative ultrasonography and surgery between June 2010 and March 2015 at Renmin Hospital of Wuhan University were retrospectively analyzed. Clinical factors, preoperative ultrasound features and the final pathological findings were obtained...

PURPOSE: The aim of this study was to compare pH meter and neck ultrasonograph for evaluation of nasogastric tube (NGT) position. METHODS: A total of 35 adult patients who required NGT insertion were included. The NGT was inserted by an anesthetist after endotracheal intubation, and the transducer was placed transversely on the neck, just superior to the suprasternal notch. The passage of the NGT in the esophagus was evaluated by a sonographer, and the stomach was emptied by nasogastric suction...

OBJECTIVES: Ultrasound (US) imaging of the airway may be useful in predicting difficulty of airway management (DAM); but its use is limited by lack of proof of its validity and reliability. We sought to validate US imaging of the airway by comparison to CT-scan, and to assess its inter- and intra-observer reliability. We used submandibular sonographic imaging of the mouth and oropharynx to examine how well the ratio of tongue thickness to oral cavity height correlates with the ratio of tongue volume to oral cavity volume, an established tomographic measure of DAM...

OBJECTIVES: (1) Assess the association between the B-mode morphologic appearance and elasticity in the rotator cuff tendon using shear wave elastography (SWE). (2) Assess the association between SWE and symptoms. METHODS: Institutional Review Board approval and informed consent were obtained. A retrospective review identified 21 studies in 19 eligible patients for whom SWE was performed during routine sonographic evaluations for shoulder pain. Evaluations were compared with 55 studies from 16 asymptomatic volunteers and 6 patients with asymptomatic contralateral shoulders...

OBJECTIVES: The aim of this study was to investigate whether sonography is a reliable tool for measuring deep abdominal muscle activation in different static arm positions while standing. METHODS: Sonographic recordings were made of the transversus abdominis and obliquus internus abdominis in 4 different static arm positions that varied with regard to the postural demand and loading direction posed on the trunk. Ten nonconsecutive repetitions of each arm position were performed, and thickness measurements were made at 2 locations within each muscle...

OBJECTIVES: To evaluate the influence of examiner experience on the accuracy of sonographic weight estimation and to further analyze examiners' individual learning curves. METHODS: In this multicenter study, 4613 sonographic weight estimations performed by 18 examiners at the beginning of their ultrasound training were included. To assess the effect of experience on the accuracy of weight estimation, a multivariable mixed regression model analysis was performed, with percentage error and absolute percentage error as outcome variables and the examiner, the examiner's experience (number of examinations), birth weight, gestational age, scan-to-delivery interval, and maternal body mass index as fixed effects and the perinatal center as random intercepts...
