We were delighted to discover that our review article Important physical principles in anaesthesiology was well-received and has provoked ideas for further improvement. It was our intention at the time only to focus on basic physical principles and not to include extra details with respect to more specialized techniques which an anaesthesiologist does not meet daily. If the details of the function of an MRI scanner was to be included, by the same argument we should have included details concerning microshock, defibrillators, isotopes, radiation, lasers, optical fibres etc. These would have made the review article unnecessarily long and, we believe, would have gone beyond the scope of a review article on basic physical principles. We are grateful to Dr Kampen and colleagues for their excellent explanation of some of the physical principles surrounding the use of the MRI scanner.
