Procurement Trends: MRI - February, 2017

​

Magnetic resonance imaging (MRI) systems use strong electromagnetic fields and radio-frequency radiation to produce computer generated images of anatomic structures. Models can be grouped into three broad categories which differ by the field strength of the magnet: 3T scanners, 1.5T scanners, and open (1.2T or less) scanners. SELECTplus member interest in 1.5T scanners increased from 60% in 2013 to 68% in 2016. There may be several possible explanations for this increase: 1.5T systems meet the routine imaging...
