Dear Sir,

With interest we took note of a review on health effects and safety of Magnetic Resonance Imaging by Drs Ng, Faust and Acharya U, published online on March 30 2010 in the Journal of Medical Systems [1]. As adequately described by the authors there are a wide number of advantages to the use of MRI as a medical imaging modality that have led to improved diagnostic outcomes without the drawbacks of for example the use of X-rays; hence the exponential growth in usage since its first introduction in the late 1970s [2]. Nonetheless, there are several serious drawbacks related to the strong static and time-varying magnetic fields and radiofrequency fields required for scanning which as discussed by the authors require specific safety recommendations.

Unfortunately, set out as a review of current knowledge of adverse health effects and current safety issues related to MRI environments for both patients and staff members this review fails to achieve its aim. Surprisingly, the most...
