MR-Compatible Instrumentation

Abstract

Various instruments and devices are required for diagnostic imaging, as well as for all kinds of interventions. As indicated by its name, magnetic resonance imaging is based on the use of a magnetic field. Various scanner designs with different field strengths and shielding techniques have been introduced over recent years. The inherent magnetism of the imaging system itself has remained common to all of these innovations. Hence, the earliest and most fundamental definition of “MR compatibility” is synonymous with non-ferromagnetic. For safety reasons, only non-ferromagnetic devices and instruments should be allowed in the MRI suite (Fig. 36.1). All personnel must receive safety training in order to prevent the accidental introduction of ferromagnetic devices into the MR suite, as these can cause serious injury to both the patient and the medical team.
