RESUMO
Non-alcoholic fatty liver disease (NAFLD) is a spectrum of disease from fatty accumulation (steatosis), necro-inflammation though to fibrosis. It is of increasing global prevalence as a hepatic manifestation of the metabolic syndrome. Although accurate histopathology and magnetic resonance imaging techniques for hepatic fat quantification exist, these are limited by invasiveness and availability, respectively. Ultrasonography is potentially ideal for assessing and monitoring hepatic steatosis given the examination is rapid and readily available. Traditional ultrasound methods include qualitative B-mode for imaging markers, such as increased hepatic parenchymal echogenicity compared to adjacent renal cortex are commonplace; however, there is acknowledged significant interobserver variability and they are suboptimal for detecting mild steatosis. Recently quantitative ultrasound metrics have been investigated as biomarkers for hepatic steatosis. These methods rely on changes in backscatter, attenuation, and speed of sound differences encountered in a steatotic liver. Prospective studies using quantitative ultrasound parameters show good diagnostic performance even at low steatosis grades and in NAFLD. This review aims to define the clinical need for ultrasound-based assessments of liver steatosis, to describe briefly the physics that underpins the various techniques available, and to assess the evidence base for the effectiveness of the techniques that are available commercially from various ultrasound vendors.

AIM: To enhance ultrasound teaching delivery to radiology trainees using a simulation course matched to the 2021 Royal College of Radiologists (RCR) curriculum. MATERIAL AND METHODS: An ultrasound simulation training course was designed for specialty trainees (ST) 1 in radiology, which was based on the 2021 RCR curriculum and covered the top ultrasound training priorities. The course was piloted initially on two occasions in a 1-day format to the August 2021 and the March 2022 ST1 intake trainees. Based on the feedback, a comprehensive 4-day course was developed and delivered between October and December 2022 for the August 2022 ST1 intake, funded by Health Education England. The outcomes measured were subjective trainee feedback using numerical scores and free text. RESULTS: All King's College Hospital NHS Foundation Trust radiology ST1 trainees from the August 2021 to the August 2022 intake participated in ultrasound simulation training. The training matched the RCR curriculum and increased the trainees' confidence and competency in medical ultrasound. CONCLUSIONS: Ultrasound simulation training can be successfully delivered to ST1 trainees to match the 2021 RCR curriculum and enhance training in medical ultrasound for radiologists.

Ultrasound-based elastography has rapidly replaced the need for liver biopsy in most patients with chronic liver disease in recent years. The technique is now widely supported by many manufacturers. This review will introduce various current ultrasound-based elastography techniques, review the physics and scanning techniques, discuss potential cofounding factors as well as summarising the evidence for its use in staging liver fibrosis using shear-wave elastography among different disease aetiologies. Future challenges and directions will be also be discussed.

AIM: To report the severity and extent of pulmonary thromboembolic disease (PTD) in COVID-19 patients undergoing computed tomography pulmonary angiography (CTPA) in a tertiary centre. MATERIALS AND METHODS: This is a retrospective analysis of COVID-19 patients undergoing CTPA over a period of 27 days. The presence, extent, and severity of PTD were documented. Two observers scored the pattern and extent of lung parenchymal disease including potential fibrotic features, as well as lymph node enlargement and pleural effusions. Consensus was achieved via a third observer. Interobserver agreement was assessed using kappa statistics. Student's t-test, chi-squared, and Mann-Whitney U-tests were used to compare imaging features between PTD and non-PTD sub-groups. RESULTS: During the study period, 100 patients with confirmed COVID-19 underwent CTPA imaging. Ninety-three studies were analysed, excluding indeterminate CTPA examinations. Overall incidence of PTD was 41/93 (44%) with 28/93 patients showing small vessel PTD (30%). D-dimer was elevated in 90/93 (96.8%) cases. A high Wells' score did not differentiate between PTD and non-PTD groups (p=0.801). The interobserver agreement was fair (kappa=0.659) for parenchymal patterns and excellent (kappa=0.816) for severity. Thirty-four of the 93 cases (36.6%) had lymph node enlargement; 29/34 (85.3%) showed no additional source of infection. Sixteen of the 93 (17.2%) cases had potential fibrotic features. CONCLUSION: There is a high incidence of PTD in COVID-19 patients undergoing CTPA and lack of a risk stratification tool. The present data indicates a higher suspicion of PTD is needed in severe COVID-19 patients. The concomitant presence of possible fibrotic features on CT indicates the need for follow-up.

Current pharmacotherapies for depression exhibit slow onset, side effects and limited efficacy. Therefore, identification of novel fast-onset antidepressants is desirable. GLO1 is a ubiquitous cellular enzyme responsible for the detoxification of the glycolytic byproduct methylglyoxal (MG). We have previously shown that MG is a competitive partial agonist at GABA-A receptors. We examined the effects of genetic and pharmacological inhibition of GLO1 in two antidepressant assay models: the tail suspension test (TST) and the forced swim test (FST). We also examined the effects of GLO1 inhibition in three models of antidepressant onset: the chronic FST (cFST), chronic mild stress (CMS) paradigm and olfactory bulbectomy (OBX). Genetic knockdown of Glo1 or pharmacological inhibition using two structurally distinct GLO1 inhibitors (S-bromobenzylglutathione cyclopentyl diester (pBBG) or methyl-gerfelin (MeGFN)) reduced immobility in the TST and acute FST. Both GLO1 inhibitors also reduced immobility in the cFST after 5 days of treatment. In contrast, the serotonin reuptake inhibitor fluoxetine (FLX) reduced immobility after 14, but not 5 days of treatment. Furthermore, 5 days of treatment with either GLO1 inhibitor blocked the depression-like effects induced by CMS on the FST and coat state, and attenuated OBX-induced locomotor hyperactivity. Finally, 5 days of treatment with a GLO1 inhibitor (pBBG), but not FLX, induced molecular markers of the antidepressant response including brain-derived neurotrophic factor (BDNF) induction and increased phosphorylated cyclic-AMP response-binding protein (pCREB) to CREB ratio in the hippocampus and medial prefrontal cortex (mPFC). Our findings indicate that GLO1 inhibitors may provide a novel and fast-acting pharmacotherapy for depression.

AIM: To establish the feasibility and accuracy of contrast-enhanced ultrasound (CEUS) nephrostogram in comparison to the reference standard, fluoroscopic nephrostogram, in providing alternative imaging of the urinary tract post-nephrostomy insertion. MATERIALS AND METHODS: This prospective study was approved by the institutional and national ethics committee. All patients for whom a fluoroscopic nephrostogram was requested were included. Fluoroscopic and CEUS nephrostograms were performed within 24 hours. Image analysis (nephrostomy position, opacification of pelvicalyceal system, ureter, and bladder) was performed by two reviewers, and the diagnostic accuracy of the CEUS nephrostograms was compared to fluoroscopic nephrostograms. RESULTS: Sixty-two nephrostograms were performed in 48 patients from June 2011 to April 2016, (male: 25/48, 52.1%; mean age 65 years, range 28-90 years). Indications for nephrostomy were: malignancy (29/62; 46.8%), benign ureteric stricture (14/62; 22.6%), urinary diversion (8/62; 12.9%), renal calculus (5/62; 8.1%), haematoma (3/62; 4.8%) or pelvi-ureteric junction obstruction (3/62; 4.8%). Two nephrostomies were identified as displaced by both techniques. The pelvicalyceal system was visualised in 60/60 (100%) examinations in both fluoroscopic and CEUS nephrostograms. The entire ureter was visualised in 30/60 (50%) with CEUS compared to 32/60 (53.3%) fluoroscopically. The distal ureter was the least well-visualised segment for both techniques with no significant difference (p=0.815). Both CEUS and fluoroscopy could be used to correctly identify complications including entero-ureteric fistula or urine leak. Fluoroscopic nephrostogram demonstrated drainage into the bladder in 33/60 (55%), CEUS confirmed drainage in 34/60 (56.7%) cases (p=0.317). CONCLUSIONS: CEUS nephrostogram can determine the correct positioning of a nephrostomy and assess drainage into the bladder with statistically comparable results to fluoroscopy.

In these days of political vagueness, to use a kinder term, although many would describe the situation as turmoil, in Europe, there are success stories to be lauded. Notwithstanding the direction individual countries choose in relation to closer or not so close co-operation in Europe and the direction the political agenda will travel over the next few years, I believe science and in particular medicine has benefited enormously form close co-operation across the European Union and with colleagues outside this political and trading block of nations. Ultrasound within the community of medical scientists and clinicians is a unique imaging tool that links various disparate specialities that collaborate little in any sphere other than imaging with the tool of sonography. An umbrella organization that allows co-operation between the medical specialities, and brings basic scientist under one roof to co-operate closely is undoubted of benefit ultimately with the customer, in this case the patient.The European Federation of Societies of Ultrasound in Medicine and Biology (EFSUMB) has over the last few years in particular achieved this unique position of bringing together peoples from across the European nation in collaboration in numerous projects, using skilled expertise from different nations to forge the common aim of advancing the practice of ultrasound as applied to biology and medicine. The success of this collaboration is demonstrated by the number of guidelines issued by EFSUMB over the years, well received across the globe and respected by numerous citations in the literature. The main areas of expertise has been in the guidelines associated with contrast ultrasound 1 2 and elastography 3 4, but also with guidelines pertaining to interventional ultrasound 5, student education 6 and recently contrast ultrasound in paediatric practice 7. More guidelines are planned, with input from many different experts from societies within the family of EFSUMB. These guidelines set the benchmark for ultrasound practice across the world and are often mimicked by others.This collaboration and continued output is important. With the recent Food and Drug Administration (United States of America) approval of the use of an ultrasound contrast agent for focal liver lesions, a worldwide change of practice will occur. This was achieved without a clinical trial in children, a previously unheard of occurrence and solely based on the experience, expertise and pioneering activities of investigators in Europe, many embolden by the support of colleagues across Europe sharing experience through EFSUMB. The lead in establishing ultrasound elastography has also originated in Europe with close and strong collaboration to produce guidelines, again pioneering the application of elastography to clinical situations. More important guidelines are on the horizon dealing with liver elastography, non-hepatic contrast ultrasound and gastrointestinal ultrasound.This success translates to the success of the journal, Ultraschall in der Medizine/European Journal of Ultrasound, with a rising impact factor, rising manuscript submissions and limited space. Where can authors in Europe publish their innovative research to continue this journey? This is one of the pitfalls of the European success story, perhaps in time we can resolve this by increasing on-line papers, increasing page numbers in the journal etc. but this is a problem of the publication industry in general.The most important element from this success story has to be the success of collaboration across the borders of the European nations, and this has also to be the success of the European Union in achieving this close scientific and medical environment. The potential adverse effect this will have on the scientific collaboration in the United Kingdom, my own area of professional activity, following a vote to re-consider membership of the European Union, is largely unpredictable. Nevertheless this is of great concern to many of us in the United Kingdom that an opportunity may be lost, with new generations of medical doctors no longer able to travel and work freely across Europe, bring ideas with them, and returning with new ways to practice. I have undoubtedly benefited from the numerous overseas doctors who have come to work in my own department over many years. My own hope is that the seeds of collaboration are so embedded in our work routine that we in the scientific and medical community have now forever achieved collaboration as a second nature which will be only strengthened with any political fallout across Europe. The time for continuing support for an umbrella organization for the advancement of medicine and biology in ultrasound has never been greater.

The sixth part of the Guidelines on Interventional Ultrasound produced under the auspices of the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) assesses the evidence for ultrasound guidance and assistance in vascular interventions. Based on convincing data, real-time sonographic guidance for central venous access is strongly recommended as a key safety measure. Systematic analysis of scientific literature shows that in difficult situations and special circumstances US guidance may also improve the efficacy and safety of peripheral venous and arterial access and endovascular interventions. Moreover, the recommendations of this guideline endorse the use of ultrasound to detect complications of vascular access and US-guided interventional treatment of arterial pseudoaneurysms.

PURPOSE: Increased prevalence of germ cell tumour (GCT) is seen with testicular microlithiasis (TM) suggesting TM is a premalignant condition with US surveillance advocated. We present a cohort of patients with TM followed up in a single centre and deliberate on the value of US surveillance. MATERIALS AND METHODS: A retrospective analysis of subjects with underlying US diagnosis of TM between 1998 and 2012. One-yearly US follow-up was offered to all patients with TM and a database maintained. Any co-existing tumour at presentation with TM was recorded. TM was divided into limited (<â5 microliths/field), classical (≥â5 microliths/field) and florid ('snowstorm' appearance). Patient demographics, follow-up details and the development of any scrotal abnormalities were recorded. The radiological and histological findings were documented when a testicular lesion occurred during the follow-up period. RESULTS: 20â224 patients were examined: 867/20â224 (4.3â%) had TM. 21/867 (2.4â%) patients had histology proven malignant tumours at presentation. All TM patients consented to follow-up with 442/867 (51.0â%) achieving this and entering into a follow-up program (mean duration 28 months, range 8â-â165 months). Two patients developed primary GCT during the follow up period. One patient (limited TM) had undergone a previous orchiectomy for contralateral GCT and developed a palpable mass at follow up month 21. The other (limited TM) had an atrophic testis; a tumour was found on US at follow up month 62. CONCLUSION: Two patients of 442 (0.5â%) followed up for all forms of TM in a single centre developed a GCT over a mean duration of 28 months, both had independent risk factors for the development of GCT. These findings suggest that US surveillance is not required when TM is the only abnormality in the absence of any clinical risk factors for the development of GCT.

The fourth part of the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) Guidelines on Interventional Ultrasound describes general aspects of endoscopic ultrasound-guided diagnostic and therapeutic interventions and assesses the evidence for endoscopic ultrasound-guided sampling. Endoscopic ultrasound combines the most advanced high-resolution ultrasound imaging of lesions within the wall and in the vicinity of the gastrointestinal tract and safe and effective fine needle based tissue acquisition from these lesions. The guideline addresses the indications, contraindications, techniques, adverse events, training and clinical impact of EUS-guided sampling. Advantages and drawbacks are weighed in comparison with image-guided percutaneous biopsy. Based on the most current evidence, clinical practice recommendations are given for crucial preconditions and steps of EUS-guided sampling as well as for safe performance. Additionally, the guideline deals with the principles and reliability of cytopathological reporting in endoscopic ultrasound-guided sampling (long version).

High-resolution ultrasound (US), as a readily available, cost-effective and harmless imaging technique, is appropriately the initial imaging modality for salivary gland lesions. Benign tumors are reported to present with regular and well-defined margins, a homogeneous hypoechoic structure and demarcated vessel distribution, whereas malignant lesions are irregular, heterogeneous and diffusely perfused. Ultrasound and color Doppler features of benign and malignant salivary gland lesions overlap, and many benign tumors, particularly pleomorphic adenomas, may appear irregularly shaped, with a heterogeneous echo-structure indistinguishable from a malignant lesion. Often skilled US operators are not always able to differentiate benign from malignant lesions. The introduction of US contrast agents has allowed further perspectives in the possible improvement of lesion characterization, and the emergence of US elastography, an innovative tool for assessing lesion stiffness/elasticity characteristics, has been advocated for differentiating salivary gland lesions. When lesions are atypical on US, contrast-enhanced magnetic resonance (MR) imaging is usually the definitive imaging modality. We present a current review of benign and malignant parotid gland tumors with emphasis on the role of multiparametric US and MR imaging.
