What is Magnetic Resonance Imaging Scans (MRI)

Encyclopedia of Information Science and Technology, Fifth Edition
Represents the most accurate spatial imaging of soft tissues of the investigated site that is a direct insight into the interior without surgical intervention with maximum accuracy. It allows very detailed views of organs and tissues throughout the body without the need for X-rays or ionizing radiation. MRI employs strong static and low frequency time-variable magnetic fields along with radio waves that, in a connection with computer processing, produce images showing injury, disease process, or the presence of abnormal tissues.

Abstract
The health system's performance consists of three components: efficiency, availability, and resilience. These three economic categories are also influenced by the distribution of medical devices and equipment, both by the quality of satisfaction of medical needs, by geographical availability and by the cost - the degree of financial burden on the health system. However, only few research studies deal with the issue of regional disparities in the use of selected medical technology. The aim of presented study is to map the distribution of the magnetic resonance imaging scans in Slovak republic within the timespan 2008-2017 on NUTS 3, respectively NUTS 4 level. Correspondence analysis shows hidden associations between the analysed variables. Our results show that magnetic resonance imaging scans are highly concentrated in two big cities. Generally, the number of magnetic resonance imaging scans has increased over time from 0.6 scans per 100 000 habitants in 2008 to approximately 0.94 scans per 100 000 habitants in 2017.
