Ischemic gallbladder perforation

Background: A 63-year-old woman was admitted to the department of vascular surgery with abdominal angor and hypertension. Abdominal CT angiography revealed occlusion of the celic trunk and superior mesenteric trunk and severe stenosis on the left renal artery. Stenting of the left renal artery was successfully performed. One week after the procedure, the patient was admitted at the emergency department with severe abdominal pain, which began a few hours before admission

Mdct imaging before transcutanous aortic valve implantation: rationale and measurements

Since its introduction in 2002, transcatheter aortic valve implantation (TAVI) has assumed growing importance in the treatment of patients with severe aortic stenosis (AS), because it offers a much less invasive alternative for those in high risk for surgery. Good early results and advances in percutaneous valve technology have led to a substantial increase in procedural success rate and number of patients undergoing this less invasive treatment. Pre-procedural screening of several anatomic factors to assess the feasibility of this technique is important. Multidetector row computed tomography (MDCT) is the technique of choice in assessing these factors. This technical note aims to describe and illustrate the key elements that need to be evaluated before the procedure

Periosteal chondroma of the proximal tibia mimicking Osgood-Schlatter's disease

We report a case of a periosteal chondroma of the proximal tibia in an 11-year-old girl, which was initially misdiagnosed as Osgood-Schlatter's disease. The absence of pain and meticulous analysis of the imaging findings on initial and follow-up plain radiographs, ultrasound and MRI allowed to suggest the diagnosis of a periosteal chondroma, which was confirmed after biopsy. Besides the difficulty in the imaging diagnosis of the lesion, determination of the optimal treatment strategy may be challenging as well. Given the localization of this lesion close to the growth plate, decision has to be made whether the lesion will be treated surgically or a waitful watching policy will be implemented in order to prevent interference with the normal growth of the bone

Exploring the Emergence of Open Spatial Data Infrastructures: Analysis of Recent Developments and Trends in Europe

In the past 20 years, European public authorities have invested considerable resources in the development of spatial data infrastructures. With the European INSPIRE Directive as an important driver, national spatial data infrastructures were developed throughout Europe to facilitate and coordinate the exchange and sharing of geographic data. While the original focus of these spatial data infrastructure was mainly on data sharing among public authorities, it became more and more evident that these data could also be of great value to users outside the public sector. In recent years, several countries and public administrations started to make a shift towards the establishment of an ‘open’ spatial data infrastructure, in which also businesses, citizens and non- governmental actors were considered as key stakeholders of the infrastructure. This chapter provides an analysis of the measures and solutions implemented in four European countries (the Netherlands, the United Kingdom, Denmark and Finland) to make their spatial data infrastructures open to businesses, citizens and other stakeholders. The analysis shows that in these four countries the move towards more open spatial data infrastructures can mainly be seen in the increased availability of geographic data and spatially enabled services to citizens, businesses and other stakeholders

Body of knowledge for the earth observation and geoinformation sector: A basis for innovative skills development

With new Earth Observation (EO) and Geoinformation (GI) data sources increasingly becoming available, evermore new skills for data collection, processing, analysis and application are required. They are needed not only from scientists, but also from practitioners working in businesses, public and private EO*GI and related sectors. Aligning the continuously evolving skill sets demanded by the market and existing academic and vocational training programmes is not an easy task. Training programmes should be grounded in real needs of the sector and its labour market. To do this, it is necessary to identify the knowledge and skills needed, and map their interconnectivity in specific frameworks, which can later be used for the definition of new curricula or job-oriented learning paths. This paper presents a framework for the EO*GI sector, based on a Body of Knowledge (BoK), by creating a complete set of concepts with a semantic structure underneath that supports academia and industry. Creating and updating the BoK is supported by an editing tool, the Living Textbook and by experts in the EO*GI domain, who contributes to the BoK’s enrichment
