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...

PURPOSE: To assess the diagnostic performance of a leak-plugging segmentation method that we have developed for delineating breast masses on ultrasound images. MATERIALS AND METHODS: Fifty-two biopsy-proven breast lesion images were analyzed by three observers using the leak-plugging and manual segmentation methods. From each segmentation method, grayscale and morphological features were extracted and classified as malignant or benign by logistic regression analysis...

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...

BACKGROUND AND AIM: Neonatal respiratory distress syndrome is a leading cause of morbidity in preterm new-born babies (<37 weeks gestation age). The current diagnostic reference standard includes clinical testing and chest radiography with associated exposure to ionising radiation. The aim of this review was to compare the diagnostic accuracy of lung ultrasound against the reference standard in symptomatic neonates of ≤42 weeks gestation age. METHODS: A systematic search of literature published between 1990 and 2016 identified 803 potentially relevant studies...

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...

Nigel Thomson, Paul Moloney
The Medical Defence Union has reported an increase in the numbers of sexual assault allegations against doctors, although these are still thankfully rare. This short article discusses the experience of the Society of Radiographers in advising members who have been accused of sexual assault and identifies ways in which ultrasound practitioners can reduce the risk of having such an accusation made against them.

Best practice guidelines for the disinfection of ultrasound transducers and infection prevention in ultrasound departments are generally recommended by either government health groups or the ultrasound societies of individual countries. The literature shows a wide variance in not only transducer cleaning methods but basic hygiene practices in the ultrasound workplace. This paper describes results from a UK survey of disinfection of ultrasound transducers and hygiene practice in the workplace. The survey revealed that some ultrasound practitioners did not follow current guidelines with regard to the correct disinfection method of transducers, cords or ultrasound machine keyboards...

BACKGROUND: Ultrasound can be used to facilitate lumbar puncture, especially in obese patients. METHODS: In this study, midline and paramedian approaches with curved and linear transducers were compared in patients with Body Mass Index (BMI) above 25 kg/m(2) for the identification of spinal landmarks. In each view, six major landmarks, including spinous process, ligamentum flavum, laminae, epidural space, subarachnoid space and posterior longitudinal ligament, were detected by emergency medicine residents and were then reviewed by radiologists...

BACKGROUND: Ultrasonic imaging is an integral and routine procedure in many medical applications. An increased awareness of the need for quality assurance in this field has led to numerous tests being proposed. Due to the complexity of the problem, the tests directly measuring the important parameters of resolution and contrast of low-echoic structures are not unified, often more qualitative than quantitative, and are performed at large periodic intervals. Uniform sensitivity of an array transducer is a necessary but insufficient requirement for imaging quality of an ultrasound probe...

INTRODUCTION: The Royal College of Radiologists and the Society and College of Radiographers in the United Kingdom published 'Standards for the provision of an ultrasound service', including application-specific limiting values for resolution and penetration. No measurement methods were detailed. We aimed to explore a possible theoretical basis for the standards and to develop a measurement protocol. METHODS: Since application-specific standards fail to account for probes of different frequencies used for similar applications and no evidence for the standards was provided, we developed generic standards based on theoretical considerations...

James Moggridge
BACKGROUND: Although ultrasound systems generally archive to Picture Archiving and Communication Systems (PACS), their archiving workflow typically involves storage to an internal hard disk before data are transferred onwards. Deleting records from the local system will delete entries in the database and from the file allocation table or equivalent but, as with a PC, files can be recovered. Great care is taken with disposal of media from a healthcare organisation to prevent data breaches, but ultrasound systems are routinely returned to lease companies, sold on or donated to third parties without such controls...

INTRODUCTION: This paper reports the results of an audit to assess the possible thermal hazard associated with the clinical use of ultrasound scanners in UK Hospitals for transvaginal ultrasound imaging. METHODS: An anatomically relevant phantom composed of a block of agar-based tissue mimicking material with embedded thermal sensors was developed. Seventeen hospitals around the UK were visited and a total of 64 configurations were tested. A representative typical scanning protocol was adopted, which primarily used B-mode with 30 s periods of colour-flow and pulsed Doppler modes for both gynaecology and obstetrics pre-sets...
