Vascular radiology in The Netherlands in 1992: a quantitative approach

European Journal of Radiology
P J KickenJ M van Engelshoven


A survey was held into methods and extent of vascular radiology in the Netherlands. For the year 1992, quantitative data on the number of patients, vascular radiological examinations and characteristics of angiography facilities were obtained from more than 80% of the Dutch hospitals with angiography rooms (120). The following estimates have been inferred: approximately 50,600 patients were referred for non-cardiac vascular radiology, including 32,100 patients for intra-arterial arteriography, 8900 for intravenous DSA arteriography, 4600 for phlebography and 5000 for interventional radiology. On average about two vascular examinations were carried out per patient referred for arteriography. In interventional radiology, the number of patients and the number of examinations are quite similar. The total number of angiography rooms in the Netherlands was 136. The average age of angiography X-ray systems was 7.1 years, of imaging equipment 5.7 years. In 56% of the hospitals, the X-ray tube was normally applied in the undercouch position, in 40% in overcouch position and in 4% there was no preferred position. An additional survey of occupational exposure conditions in angiography rooms (19 hospitals) showed that, in most hospitals, p...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
