The ultrasound platform was the Siemens S2000, equipped with point-shear-wave elastometry software...

INTRODUCTION: Liver biopsies are the main method in the diagnosis and treatment of paediatric liver pathologies. Major complication rates of paediatric liver biopsies range from 0% to 6.6% in the literature and minor complication rates range from 0% to 25%. In this study, we aimed to review the complications, indications and results of percutaneous core liver biopsies with paediatric sonography in a tertiary care centre by an interventional radiologist. METHODS: We retrospectively evaluated the results, indications and complications of paediatric liver biopsies performed in our tertiary health centre between January 2017 and December 2020...

INTRODUCTION: Cavernous haemangioma is the most common benign non-infiltrative neoplasm of the orbit. Most cavernous haemangiomas are intraconal and lateral in location. CASE REPORT: We present a rare case of a cavernous haemangioma with an unusual location in the supraorbital region of the orbit, presenting with soft tissue swelling. DISCUSSION: Cavernous haemangiomas are the most common benign non-infiltrative neoplasms of the orbit and have a slowly progressive mass effect...

INTRODUCTION: Saving Babies' Lives Care Bundle Version 2 highlights the importance of correct identification and reporting of echogenic bowel to improve maternal and newborn outcomes. Yet there is no national consensus to guide sonographers in identifying and reporting fetal echogenic bowel. This two-phase study aims to develop a national consensus to guide sonographers on the identification, classification and reporting of fetal echogenic bowel during the Fetal Anomaly Screening Programme (FASP) second trimester anomaly scan...

INTRODUCTION: Point-of-care ultrasound is becoming increasingly popular, and we sought to examine its role in evaluating ocular and periocular structures and facial vasculature. With the large number of point-of-care ultrasound devices available, it is difficult to determine which devices may be best suited for ophthalmic and facial aesthetic applications. This study compares five popular handheld point-of-care ultrasound devices to help guide clinicians in choosing the device best suited for their needs...

INTRODUCTION: Hepatic portal venous gas is a rare and life-threatening condition characterised by the presence of gas in the portal vein. Hepatic portal venous gas is frequently associated with intestinal ischaemia and necrosis. We present the case of a paediatric patient with acute appendicitis with hepatic portal venous gas detected using ultrasonography. CASE REPORT: A 5-year-old boy was admitted to our hospital with a respiratory tract infection. The boy started vomiting on day 2 of hospitalisation...

BACKGROUND: Intracranial atherosclerotic stenosis is a common cause of ischemic cerebrovascular events and is associated with a high risk of stroke recurrence. This study aimed to assess the diagnostic accuracy of transcranial color-coded duplex sonography for moderate-to-severe middle cerebral artery stenosis in stroke patients. METHODS: A retrospective analysis was carried out, including 31 patients aged ⩾18 years hospitalized for ischemic cerebrovascular event in whom middle cerebral artery stenosis ⩾30% was identified on computed tomography angiography...

INTRODUCTION: Adenomyosis is histologically defined by the presence of endometrial glands and stroma in the myometrium. Ultrasound findings of adenomyosis are being redefined to better diagnose adenomyosis pre-operatively. METHODS: A single-centre retrospective study was performed at a regional hospital. The myometrial-cervical ratio was calculated on pre-operative ultrasounds, and histopathology reviewed for each case. Logistic regression was used to estimate the association between the myometrial-cervical ratio and adenomyosis confirmed on histopathology, and the area under the receiver operating characteristic curve was calculated...

INTRODUCTION: Patients with posterior knee swellings are commonly encountered in clinical practice with the vast majority referred for an ultrasound scan to assess for a clinically suspected Baker's cyst. AIMS: Our aim was to determine the incidence of different pathologies in patients investigated for a posterior knee swelling of a clinically suspected Baker's cyst using ultrasound. We also wanted to investigate the incidence of significant pathologies in the popliteal fossa to assess whether the ultrasound scan findings influenced patient management...

INTRODUCTION: Despite widespread recognition that communicating unexpected news during obstetric ultrasound examinations is challenging, there is a dearth of research investigating how to teach evidence-based communication to sonographers. Communication Coaching is a supportive, positive method that has previously been associated with improvements in communication, patient satisfaction, and reduced burnout in clinicians. However, to date, no study has coached sonographers. This study explored stakeholders' views on a proposed Communication Coaching intervention and used these data to adapt the intervention for use with qualified obstetric sonographers...

INTRODUCTION: Acute appendicitis is traditionally a clinical diagnosis where there are a range of diagnostic accuracies reported. The role of ultrasound is to improve specificity and decrease negative appendicectomy rate. It is a simple, non-invasive, easily available technique.The purpose of this study is to determine the diagnostic accuracy of an ultrasound in combination with total leukocyte count, neutrophil percentage and C-reactive protein in diagnosing acute appendicitis. METHODS: This study includes consecutive sampling of suspected patients from January 2021 to February 2022 with the approval of the ethical and research committee...

PURPOSE: To evaluate the segmental variations in portal venous pulsed wave colour Doppler flow velocity in patients with moderate to severe non-alcoholic fatty liver disease in comparison with healthy controls. MATERIALS AND METHODS: In this prospective, observational, case-control study, the maximum velocity of all the segmental branches of portal vein were evaluated on colour Doppler in patients with moderate to severe non-alcoholic fatty liver disease, and the values were compared between three groups (1) Healthy controls ( n  = 30), (2) non-alcoholic fatty liver disease group, that is moderate to severe fatty liver without features of portal hypertension ( n  = 32) and (3) non-alcoholic steatohepatitis-portal hypertension group, that is those non-alcoholic fatty liver disease patients with features of portal hypertension ( n  = 13)...

INTRODUCTION: Accessory spleen is a congenital defect characterised by a separated ectopic splenic parenchyma usually located in the splenic hilum and the tail of the pancreas. It is present in about 10%-30% of the population and, generally, does not cause any symptoms. CASE REPORT: We report an interesting case of a woman with symptomatic intramesenteric accessory spleen detected and characterised by contrast-enhanced ultrasound. The patient experienced a long history of intermittent pain in the left upper abdomen...

OBJECTIVES: The microcystic, elongated and fragmented pattern of invasion can be associated with an underestimation of the depth of myometrial invasion by imaging techniques. We aimed to evaluate the influence of microcystic, elongated and fragmented pattern of invasion in the diagnostic performance of transvaginal ultrasound scan and magnetic resonance imaging for the prediction of the depth of myometrial invasion in low-grade endometrioid endometrial carcinomas. METHODS: Prospective and consecutive study including all low-grade (G1-G2) endometrioid endometrial carcinomas diagnosed between October 2013 and July 2018 in a tertiary hospital...

BACKGROUND: Liver stiffness measurements can be used to assess liver fibrosis and can be acquired by transient elastography using FibroScan® and with Acoustic Radiation Force Impulse imaging. The study aimed to establish liver stiffness measurement scores using FibroScan® and Acoustic Radiation Force Impulse in a chronic hepatitis C cohort and to explore the correlation and agreement between the scores and the factors influencing agreement. METHODS: Patients had liver stiffness measurements acquired with FibroScan® (right lobe of liver) and Acoustic Radiation Force Impulse (right and left lobe of liver)...

INTRODUCTION: There is an increasing interest in using airway ultrasound to predict difficult intubation. Studies to date have excluded pregnant women in reporting airway measurements. We performed this study to compare the mean distance from skin to epiglottis in parturients to that reported in previously published studies. We also assessed the correlation of mean distance from skin to epiglottis with other elements of the airway examination. METHODS: A total of 100 parturients were recruited from a tertiary hospital's labor and delivery floor...

INTRODUCTION: Peripheral nerve sheath tumours are neurogenic neoplasms that arise from the nerve sheath which are not within the central nervous system. While most of these lesions may be benign, some of them may undergo malignant transformation, establishing why it is imperative for ultrasound practitioners to familiarise themselves with ultrasound presentations of this lesion to facilitate early and effective diagnosis, which would in turn positively impact patient management. CASE REPORT: We present an incidental finding of a thrombus-mimicking peripheral nerve sheath tumour in a female patient who came to the ultrasound department for a left leg deep vein thrombosis scan...

INTRODUCTION: The mainstay of endovascular treatment in peripheral arterial disease is digital subtraction angiography with an iodinated contrast. In patients with a known contrast allergy, the current most commonly used alternative is to perform carbon dioxide angiography. Operator experience and availability of carbon dioxide (CO2 ) angiography delivery systems are, however, limited. Intravascular ultrasound is now commonly used in combination with fluoroscopy in peripheral venous interventions and in coronary arterial disease and we propose that this also provides a safe and effective alternative option to guide endovascular intervention in patients with a known contrast allergy...

INTRODUCTION: Ultrasound estimated fetal weight is increasingly being used in the monitoring of fetal growth. Large systematic and random errors in estimated fetal weight have been reported; these may have an impact on the accuracy of fetal growth monitoring. The aim of this study was to attempt to evaluate these systematic and random errors by analysis of serial ultrasound data. METHODS: Ultrasound measurements and birthweights were retrospectively collected for 100 unselected patients who had undergone serial ultrasound...
