Background: Preterm birth is a major health problem in developing and developed countries leading to rising health care costs and long-term neurodevelopmental disability. The study aims to evaluate the role of new quantitative markers, like the elastography of cervix (shear wave speed estimation), fetal adrenal zone enlargement, and corrected fetal adrenal gland volume; in preterm birth prediction and analyze their relative importance. Thus, these markers may be beneficial in early preterm birth detection and prevent the related morbidities...

Introduction: In the UK an accurate gestational age is confirmed by ultrasound measured foetal crown rump length (CRL) at 11 + 2-14 + 1 weeks of gestation. The currently recommended Robinson and Fleming crown rump length reference chart was develop in 1975. Advances in ultrasound technology and standardized crown rump length measurement training could mean this is now out of date. Our study aimed to assess its accuracy in current routine antenatal care. Methods: Retrospective data from 178 IVF pregnancies seen for routine antenatal care at a UK Regional Maternity Unit between 1 January 2006 and 1 January 2016 was retrieved...

Introduction: A functionally single cardiac ventricle seen on foetal ultrasound scan carries a guarded prognosis. The antenatal diagnosis of anomalous pulmonary venous connection (APVC) remains challenging, if there is no associated structural cardiac abnormality. Antenatally, a combination of complex cardiac anomaly with suspected isomerism should raise the possibility of associated total anomalous pulmonary venous connection (TAPVC). There needs to be a high index of suspicion for TAPVC, in functional single ventricle and suspected isomerism, as this carries a very grim outcome postnatally...

Julia Milner, Jane Arezina
Ultrasound estimation of fetal weight is a highly influential factor in antenatal management, guiding both the timing and mode of delivery of a pregnancy. Although substantial research has investigated the most accurate ultrasound formula for calculating estimated fetal weight, current evidence indicates significant error levels. The aim of this systematic review was to identify the most accurate method, whilst identifying sources of inaccuracy in order to facilitate recommendations for future practice. Seven studies met the inclusion criteria and 11 different formulae were assessed; ultrasound calculation of fetal weight was most commonly overestimated...

Introduction: Congenital splenic cysts are a rare cause of abdominal cystic masses in the fetus. We describe nine cases of this condition, the largest reported experience to date. A review of the literature for similar cases was also performed. Methods: Cases of congenital splenic cyst were collected from three prenatal diagnostic centers and from a dedicated website of prenatal diagnosis. Information regarding clinical and sonographic findings was obtained by reviewing ultrasound reports and medical records...

The purpose of this study was to investigate the diagnostic performance of the head-perineum distance, angle of progression, and the head-symphysis distance as intrapartum ultrasound parameters in the determination of an engaged fetal head. Two hundred and one women in labour underwent both ultrasound and digital vaginal examination in the estimation of fetal head station. The transperineal ultrasound measured head-perineum distance, angle of progression, and head-symphysis distance for values correlating with digital vaginal examination head station...

REVIEW
Gillian Coleman, Heather Venables
Vasa praevia is an obstetric complication currently not screened for within the United Kingdom, which if undetected prenatally can lead to fetal death when the membranes rupture. Internationally, guidelines are available providing guidance on the best screening policy and management pathways. However, the UK National Screening Committee and Royal College of Obstetricians and Gynaecologists do not support screening due to a lack of evidence. Recent studies explore the ability of ultrasound to detect vasa praevia prenatally in both the general and high-risk populations...

Persistent truncus arteriosus is a rare congenital cardiac malformation. It is characterized by a single great artery arising from the heart which supplies the aorta, the origin of coronary arteries and pulmonary arteries. Without surgery, prognosis is poor and 90% of these patients die before one year of age. We report a rare case of an asymptomatic 35-year-old woman with uncorrected persistent truncus arteriosus and hypoplastic right and left pulmonary arteries. Hypoplastic branch pulmonary arteries prevented the development of severe pulmonary arterial hypertension...

Lung ultrasound is increasingly utilized as a diagnostic tool for the detection of a pneumothorax. The effect of small changes in patient positioning on the accuracy of lung ultrasound to detect a pneumothorax is not well studied. We present the first known case of lung ultrasound missing a pneumothorax because of suboptimal patient positioning, and discuss the implications of our findings for clinicians that utilize lung ultrasound and for future research.

Foreign body impaction at the cricopharyngeal level can be a life-threatening emergency. While traditionally, removal of these is performed in the operating room setting, patients with relatively unstable airways or significant discomfort may require immediate extraction to prevent further injury. This is the case of an 85-year-old man who presented to the emergency department in significant discomfort following aspiration of a large partial denture. We report here the first known use of ultrasound in an emergent airway situation to rapidly localize and retrieve an aspirated foreign body...

Xiaowei Zhou, Peter R Hoskins
Background: A blood-mimicking fluid developed by Ramnarine et al. has been widely used in flow phantoms for ultrasound flow imaging research, and it has also been cited by IEC 61685 as a reference for making blood-mimicking fluid.However, the surfactant material Synperonic N in this blood-mimicking fluid recipe is phased out from the European market due to environmental issues. The aim of this study is to test whether Synperonic N can be substituted by biodegradable Synperonic A7 in making blood-mimicking fluid for ultrasound flow imaging research...

Ultrasound image degradation originates primarily from transducer defects and potentially undermines reliable image interpretation. Systematic quantitative quality control is often neglected due to the limited resources available for this task. We propose a quantitative quality control based on in-air reverberation images. These images serve as an initial indication of image degradation. They are easily generated for any (curvi-)linear transducer independent of the level of expertise of the operator. Automated analysis is presented to extract quality parameters based on the in-air reverberation pattern...

The aim of this study was to assess changes in shear wave velocity within the pronator quadratus muscle in patients following volar plate fixation for distal radial fractures compared to the contralateral nonoperated side. Shear wave velocity values were obtained in the short and long axis of the pronator quadratus muscle, which were analyzed separately. Patients were also stratified by age below or above 66 years. Statistical analysis was performed using paired sample Wilcoxon signed rank and t tests. Pearson and Spearman rank correlations were also used...

Objective: Liver cirrhosis has been a rising complication of chronic liver disease in Singapore. Ultrasound has been widely accepted as a non-invasive imaging modality for the evaluation of hepatic haemodynamics. This study aims to correlate the Doppler ultrasound values with the progression of liver cirrhosis to allow further understanding and possible prediction of clinical events for timely intervention. Methods: Study sample of 56 eligible patients with liver cirrhosis was divided according to their Child-Pugh clinical score into Child's A (n = 29 patients), B (n = 19 patients) and C (n = 8 patients)...

Aim: To evaluate (1) the usefulness of thoracic ultrasound in diagnosis and staging of bronchogenic carcinoma by comparing lesion detectability between thoracic- ultrasound and computed tomography and (2) the outcome of thoracic-ultrasound-guided biopsy in diagnosing bronchogenic carcinoma. Methods: We conducted a cross-sectional study on 53 patients of confirmed bronchogenic carcinoma. All patients had been investigated by thoracic-ultrasound and chest-computed tomography; data regarding the presence of mass (its size, necrosis), lymph nodes invasion, peritumoural atelectasis, consolidations, pleural effusion, chest wall invasion, and paralysis of the diaphragm were recorded...
