Magnetic resonance imaging: bioeffects and safety concerns.
Magnetic resonance imaging (MRI) is the state-of-the-art noninvasive imaging modality in clinical diagnosis. During MRI examination, the patient is exposed to three different forms of electromagnetic radiation: (i) a static magnetic field, (ii) gradient magnetic fields, and (iii) radiofrequency (RF) fields. Each of these may cause significant adverse bioeffects if applied at sufficiently high e...
متن کاملMagnetic resonance imaging safety: implications for cardiovascular patients.
The potential bioeffects associated with magnetic resonance (MR) procedures result from exposure to the static, gradient, and radiofrequency electromagnetic fields. Each electromagnetic field represents a possible health risk at sufficiently high levels of exposure. The presence of certain biomedical implants and devices may pose hazards for patients undergoing MR procedures. Additionally, othe...
متن کاملBioeffects of Static Magnetic Fields: Oxidative Stress, Genotoxic Effects, and Cancer Studies
The interaction of static magnetic fields (SMFs) with living organisms is a rapidly growing field of investigation. The magnetic fields (MFs) effect observed with radical pair recombination is one of the well-known mechanisms by which MFs interact with biological systems. Exposure to SMF can increase the activity, concentration, and life time of paramagnetic free radicals, which might cause oxi...
متن کاملMRIsafety.com. MRI safety, bioeffects and patient management
Various types of intravascular and other types of coils, stents, and filters have been evaluated for safety with MR systems. Several of these demonstrated magnetic field interactions in association with scanners. Fortunately, the devices that exhibit positive magnetic field interactions typically become incorporated securely into the vessel wall primarily due to tissue ingrowth within approxima...

Using transplanted mussels as an in-situ bioassay to assess marine environmental quality has provided important information on bioavailability of contaminants and associated bioeffects that would not have been available with traditional chemical monitoring, biomonitoring, or laboratory bioassays. It is one of the most promising field bioassay systems because of the relative ease in making synop...
