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...

David Schrift, Keith Barron, Michael Wagner, Rohan Arya
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.

Nadia Maria Shaukat, Alexis Lenz, Poonam Desai
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...

Vector flow techniques in the field of ultrasound encompass different pulse emission and estimation strategies. Numerous techniques have been introduced over the years, and recently commercial implementations usable in the clinic have been made. A number of clinical papers using different vector velocity approaches have been published. This review will give an overview of the most significant in vivo results achieved with ultrasound vector flow techniques, and will outline some of the possible clinical applications for vector velocity estimation in the future...

Vasileios Rafailidis, Claudette Phillips, Gibran Yusuf, Paul Sidhu
Intussusception is often misdiagnosed as a cause of bowel ischemia and obstruction among adults due to its relatively rare presentation outside of the paediatric population. Ultrasound is often the first-line investigation for non-specific abdominal pain and can identify the presence of intussusception. In the adult population, it is essential to evaluate for causes and consequences of intussusception; as a result, computerised tomography is often deemed necessary. However, contrast-enhanced ultrasound allows for evaluation of potential causes and complications, including a neoplastic lead point and ischaemia of the bowel, whilst avoiding ionising radiation or nephrotoxic iodinated contrast...

Pena-Shokeir phenotype is a lethal anomaly characterized by neurogenic arthrogryposis, craniofacial anomalies, and pulmonary hypoplasia. This syndrome should be distinguished from trisomy 18 and arthrogryposis multiplex congenita for better counseling and establishing fetal prognosis. We present the case of a pregnant woman diagnosed with a Pena-Shokeir phenotype affected fetus at 24 weeks of gestation. Prenatal ultrasonography and fetal magnetic resonance imaging detected persistent hyperextension of the lumbar spine, micrognathia, absent septum pellucidum, and all characteristic features of Pena-Shokeir phenotype...

AIM: Prospective study on 900 consecutive puerperae to assess normal values and range of the blood flow velocity in the middle cerebral artery in both hemispheres. MATERIAL AND METHOD: M1 and M2 segments of both middle cerebral arteries were assessed in all subjects within 96 hours of delivery. Mean flow velocity was recorded after adjusting for insonation angle. Lindegaard index (LI = middle cerebral artery-Internal Carotid Artery mean flow velocity ratio) was calculated whenever the mean flow velocity exceeded 100 cm/second...

BACKGROUND: Breast pain is one of the most common complaints of women attending a gynecology clinic and general practitioners. This pain can cause anxiety and, consequently, reduce the woman's quality of life. The objective of this study was to assess the severity of pain and anxiety in patients with breast pain and normal examination, before and after breast sonography. MATERIALS AND METHODS: Among the patients with breast pain and normal examination who came for breast sonography in three centers in Shiraz during 2011-2012, 51 patients agreed to cooperate in this project...

REVIEW
Velauthan Rudralingam, Clare Footitt, Ben Layton
The excess accumulation of intra-peritoneal fluid, referred to as ascites, is an important clue that points to a significant underlying illness. This may be due to a pathological event within the peritoneal cavity or secondary to an underlying systemic condition. Ascites is broadly classified into transudate and exudate, based on protein content, with a potential wide range of differential diagnoses. Traditionally, computed tomography has been regarded as the imaging modality of choice to demonstrate ascites and diagnose the underlying cause...
