Different times call for different measures. The COVID-19 pandemic has forced us to search for alternative methods to provide an equally qualitative and interesting annual meeting. For the Belgian Society of Radiology (BSR) 2020 Annual Meeting, the sections on Abdominal Imaging, Thoracic Imaging, and the Young Radiologist Section (YRS) joined forces to organize a meeting that is quite different from the ones we have organized in the past. We have chosen to create a compact – approximately 5 hours – and entirely virtual meeting with the possibility of live interaction with the speakers during the question-and-answer sessions. The meeting kicks off with a message from the BSR president about radiology in 2020, followed by three abdominal talks. The second session combines an abdominal talk with COVID-related talks. We have chosen to include not only thoracic findings in COVID-19, but to take it further and discuss neurological patterns, long-term clinical findings, and the progress in artificial intelligence in COVID-19. Lastly, the annual meeting closes off with a short movie about the (re)discovery of Röntgens X-ray, presented to us by the Belgian Museum for Radiology, Military Hospital, Brussels.
The meeting will take place on Saturday, November 14th 2020.
The meeting starts at 9:00 AM with a message from Dr. Piet Vanhoenacker (OLV Ziekenhuis Aalst-Asse-Ninove) (Picture 1), president of the BSR, with an overview of the activities of the BSR during the last year and the challenges that lie ahead.
The first session (10:50–12:00) focuses on abdominal imaging and is moderated by Dr. Annemie Snoeckx (Picture 12) (UZ Antwerpen) and Dr. Anne-Sophie Vanhoenacker (Picture 13) (YRS, University Hospitals Leuven). It contains three lectures about different subjects. First, Prof. Dr. Robert Dondelinger (Department of Radiology, University Hospital Sart Tilman, Liège) (Picture 2) will talk about biliary pathologies and the basic principles of treatment of bile duct obstruction. Next, Prof. Dr. Elleke Dresen (Picture 3), who is a staff member at UZ Gasthuisberg, Leuven and obtained a PhD dissertation on the multidisciplinary approach to locally advanced and recurrent rectal cancer, will give us a case-based approach as how to interpret Magnetic Resonance Imaging (MRI) of the rectum in this ‘How I do it’ talk. Finally, Dr. Philip Van Hover (Picture 4), staff member at the OLV Ziekenhuis Aalst-Asse-Ninove, with a special interest in uroradiology, will teach us tips and tricks in imaging and management of adrenal incidentaloma.
The second session (11:00–12:30) is a mix of abdominal imaging and COVID-related talks and is moderated by Dr. Lieven Van Hoe (Picture 14) (OLV Ziekenhuis Aalst-Asse-Ninove) and Dr. Flavien Grandjean (Picture 15) (YRS, CHC Liège MontLegia). First, Prof. Dr. Paul Meunier (Picture 5), Head of Radiology Department of CHU de Liège, will give an elaborate talk on the different types of abdominal internal hernias on the basis of their appearance via a normal or abnormal orifice. Next, Prof. Dr. Walter De Wever (Picture 6), thoracic radiologist and staff member at University Hospitals Leuven, will talk about the latest research on long-term pulmonary changes after COVID-19. Finally, Prof. Dr. Natalie Lorent (Picture 7), respiratory physician and staff member at the University Hospitals Leuven, will present the latest data on recovery after COVID-19 based on literature data as well as follow-up findings in UZ Leuven.
The third and final session (12:20–13:25) is moderated by Dr. Flavien Grandjean and Anne-Sophie Vanhoenacker. Prof. Dr. Sofie Van Cauter (Picture 8), certified neuroradiologist in ZOL Genk en UZLeuven, will discuss the various neurological and neuropsychiatric complications related to COVID-19. Next, the latest progress in artificial intelligence in COVID-19 will be discussed by Dr. Laurens Topff (Picture 9), radiologist at the Netherlands Cancer Institute – Antoni van Leeuwenhoek in Amsterdam, and Dr. Erik Ranschaert (Picture 10), radiologist at the ETZ Hospital in Tilburg, the Netherlands and artificial intelligence (AI) project manager. The annual meeting will end with a short movie on the (re)discovery of Röntgens X-ray, presented by René Van Tiggelen (Picture 11), radiologist and current Curator of the Belgian Museum for Radiology, Military Hospital, Brussels.

The biliary system comprises intrahepatic ducts, main extrahepatic duct and gallbladder. As for any other anatomical ductal system, biliary pathologies translate basically either into luminal obstruction or wall leakage or an association of both. Focal duct narrowing leads to dilatation above the level of obstruction and jaundice. Bile leakage ends up into formation of biloma or biliary ascites. Cholangitis, abscess, or sepsis are frequent complications in both scenarios. Causes of bile duct obstruction are malignant or benign and can be schematically allocated to preferential levels of occurrence: cholangiocarcinoma or invasive gallbladder carcinoma are characteristic for hilar obstruction, impacted gallstones, pancreatic cancer, pancreatitis or papillary disorders obstruct the distal duct. Metastatic adenopathies occur predominantly at the level of porta hepatis, the rare Mirizzi syndrome at the confluence of the cystic duct and the main duct. Bile duct obstruction caused by benign inflammatory disease, postoperative strictures, and developmental bile duct abnormalities are other clinical settings. Cross-section imaging by CT or MRI, or centered imaging during ERCP, PTC, endoscopic US and biliary endoscopy give the clue to level and cause of obstruction in the vast majority of cases. At present, diagnostic tissue is best obtained by retrograde or antegrade endocanalar forceps biopsy or brush cytology. Bile leakage can occur at any level and is predominantly related to wall injury, infection, or ischemia, as it may occur in postoperative anastomotic strictures. The basic principle of treatment of bile duct obstruction resides in any form of temporary or permanent restoration of bile flow by catheters or stents, internal drainage being preferred. Leakage is treated by catheter evacuation of a collection of bile. Reaccumulation of biloma is prevented by diversion of bile from the site of leakage and bridging the site of injury, allowing for spontaneous wall healing. Since the introduction of the skinny 22-gauge Chiba needle in 1969, percutaneous fluoroscopically guided opacification of intrahepatic bile ducts became routine, carrying a minimum of significant clinical complications, provided punctured dilated bile ducts under elevated pressure, are drained during the same session. In practice over the years, ERCP and more recently, sophisticated EUS guided techniques have evolved as standard non operative methods for both, diagnostic and therapeutic approach of bile duct pathologies. Today, percutaneous intervention to the biliary system is relegated to situations, where a retrograde catheterization is not realistic or impossible for anatomical or technical reasons, which accounts roughly for about 10% of mixed cases mainly in invasive hilar biliary obstruction or prohibitive anatomical changes. A combined small-gauge percutaneous transhepatic and endoscopic rendez-vous manœuvre carries less trauma to the liver parenchyma. Self-expandable metal stents have become established standard solutions of bile flow restoration in malignant obstruction. Retrievable covered metal stents are advised for treatment of benign strictures. Percutaneous catheter drainage of acute, acalculous or calculous cholecystitis is helpful in critically ill patients as a temporizing measure. Occasional residual postcholecystectomy gallstones are removed through a T-tube tract. Intrahepatic gallstones are retrieved during repetitive sessions through a biliary-intestinal anastomosis.

The aim of rectal cancer treatment is to provide local and distant control, in order to maximize potential for treatment success and survival. However, one treatment strategy does not fit all rectal cancer patients. The choice for optimal treatment has evolved in the last decades from standard surgery for all patients to a more individualized approach. This approach mainly depends on the risk assessment of disease recurrence. The most important risk factors are tumor and lymph node stage, distance to the anorectal junction and mesorectal fascia, and the presence of extramural venous invasion (EMVI). According to risk stratification, patients may receive surgery alone (local excision or total mesorectal excision [TME]), neoadjuvant chemoradiotherapy (in a standard or intensified scheme) followed by (extended) TME or local excision, or, in complete responders followed by a watch and wait strategy (which implies no surgery at all, but a strict follow-up program with the combination of digital rectal examination, endoscopy, and MRI). It is clear that accurate staging in this setting plays a key role in the decision-making process. While endorectal ultrasound can be very accurate in the evaluation of early-stage disease, it has to cope with disadvantages such as operator dependency, limited visibility of lymph nodes as well as limited use in cases of obstructive tumors. MRI, however, has become one of the leading imaging modalities because of its superior soft-tissue contrast, multiplanar imaging, and the possibility of functional evaluation. With the combination of high-resolution T2-weighted images and diffusion-weighted images, MRI allows accurate identification of risk factors, not only in the primary setting, but also during restaging and follow-up (Figure 1). The MRI findings should be stated in a structured report to provide the clinicians with all the information needed for an optimal treatment decision. Management of rectal cancer patients should be performed in a multidisciplinary manner, combining the expertise of all the different involved disciplines, in order to provide the patients with the highest chance of survival with the lowest morbidity.

Why adrenal imaging?
Because we have to know the difference between a malignant or benign lesion and if the lesion is secreting hormones. Which are the “dangerous” lesions, the “good” lesions and what are collision lesions. There are several techniques which we can use or on which these lesions are detected. What is the role of unenhanced CT, delayed CECT (contrast enhanced CT), in and out phase T1 imaging and one phase CECT? Also the role of PET/CT and dual source CT will be highlighted. At the end a clinical and radiological pathway will be given for daily practice.

This topic concerns a greater number of clinical situations than one would expect. In fact, internal hernias make up as many as 6% of occlusive syndromes. After a short embryological and anatomical reminder, the different types of hernias will be presented on the basis of their appearance via a normal or abnormal orifice. The different anatomical and vascular markers will be emphasized for each type of hernia in order to demystify the diagnostic reasoning. Finally, post-surgical iatrogenic hernias will be discussed.

Many clinical studies have focused on the epidemiological, clinical, and radiological characteristics of inpatients with COVID-19 disease. There are only a few reports about the clinical follow-up of discharged patients.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly contagious disease, and its first outbreak was reported in Wuhan, China. On January 30, 2020, the World Health Organization (WHO) declared it a pandemic disease. Chest CT examination has an important role in the evaluation of COVID-19 patients with false-negative RT-PCR results and studies reported the CT sensitivity as 98%. CT examinations also have great significance in monitoring disease progression and evaluating therapeutic efficacy.
Awulachew E. et al. demonstrated in his meta-analysis that common CT imaging features of COVID-19 pneumonia include frequent involvement of bilateral lung infections, ground-glass opacities (GGO), consolidation, crazy paving pattern, air bronchogram signs, and intralobular septal thickening. Bilateral involvement was common while single lobe involvement was rare. These signs of CT imaging might be an important tool for diagnosis and monitoring disease progression in patients with COVID-19 infection .
The extent of CT abnormalities progresses rapidly after the onset of symptoms, with a peak around days 6–11. The temporal changes of the diverse CT manifestations followed a specific pattern, which might indicate the progression and recovery of the illness.
At the moment of discharge, most of the patients have residual disease on chest CT scans. Ground-glass opacity is the predominant abnormality, followed by a mixed pattern (ground-glass opacity and consolidation). Pure ground-glass opacity is the most commonly seen subtype. Ground-glass opacity with irregular lines and interfaces are signs that can predict the development of interstitial fibrosis and needs long-term follow-up.
Liu et al. showed in their study that, compared with the abnormalities found on the last CT scans before discharge, the abnormalities in the lungs at the first (2 weeks) and second (4 weeks) follow-ups after discharge had been gradually absorbed. The lung lesions of 25.5% patients were shown to be fully absorbed on the first CT scans after discharge, and the rate of lung recovery increased to 64.7% after the second follow-up (Figure 1) .
Minhua Yu et al. found in their study that interstitial thickening, irregular interface, coarse reticular pattern, and parenchymal band, manifested in the process of the disease, may be predictors of the development of late pulmonary fibrosis. Irregular interface and parenchymal band could predict the formation of pulmonary fibrosis early (Figures 2 and 3) .

COVID-19, the disease caused by SARS-CoV-2 that has spread globally since the end of 2019, can present a wide spectrum of disease ranging from asymptomatic infections over mild to moderate respiratory symptoms to severe viral pneumonia with acute respiratory distress syndrome. The main target are the lungs but other organs, such as heart, kidneys, gut, can be affected in the different disease stages. Risk factors for severe disease are older age, arterial hypertension, cardiovascular disease, and chronic respiratory illness. Case fatality rates are difficult to assess based on the current data but could be as high as 1%, much higher than influenza, and this especially holds true for the elderly. Clinical outcomes of patients recovering from COVID-19 vary also by disease severity: in some cases it can result in serious lung damage with long-term consequences; however, it has been remarkable to note the recovery rate of patients following admission with moderate to severe COVID-19 pneumonia as for their clinical, radiological, and functional status. I will discuss the latest data on recovery after COVID-19 based on literature data as well as our own follow-up findings in UZ Leuven.

Various neurological and neuropsychiatric complications related to COVID-19 have been described, either during the acute phase, related to direct viral cytopathy or a para-infectious cytokine storm, as well as in later stages reflecting an immune or antibody-related inflammatory response. Although these complications are relatively rare, such patients are often severely affected, resulting in poor outcomes. In this talk, we will touch upon the mechanisms related to neuroinvasion and discuss COVID-19-related neurological disease.

Soon after the coronavirus outbreak, it became clear that medical imaging has an important role to play in the fight against COVID-19. From a strong need of both hospitals and artificial intelligence (AI) companies to tackle this pandemic, collaborations were started with a speed that would be unthinkable outside times of crisis. It became clear that in such exceptional situations with an impact on the society as a whole, there is an enormous willingness to share data, infrastructure, and AI knowledge for a common purpose. The application of deep learning has the potential to optimize and expand the role of imaging in COVID-19. In many centers, CT and/or chest X-ray was used for triage and timely diagnosis of pulmonary infection. Starting from the idea that AI-tools have the potential to support the radiologist in accurately and timely reporting radiology examinations performed in patients suspected of COVID-19, several projects were launched to develop applications for the automated analysis and quantification of pulmonary infection. The first studies on Chinese data showed that there is a relationship between the extensiveness of abnormalities on imaging and the severity of disease. In addition, it is being investigated how imaging can predict clinical evolution, such as the need for admission to intensive care or the need for ventilation. Such AI applications can play a role in future disease outbreaks. Not only in China, but also in other countries such as Belgium and the Netherlands, several initiatives to develop algorithms related to COVID-19 and radiology emerged in no time. In this presentation an overview will be provided of the different initiatives that have been undertaken in the field of AI, with a special focus on Europe. Not only the radiological and scientific, but also the technical and medical-legal aspects will be explained.

Professor Roentgen’s last will determined that all his research notes were to be burnt after his death. This is the reason why we thought it useful to make a film reconstituting how the most important discovery of the 19th century was probably made. In this movie (13’) the physical properties of X-rays are also explained.
