Q9. The main cause of nerve stimulation due to magnetic resonance imaging is the slew rate push and the maximum gradient strengths that induce field in the patient, thereby stimulating the nerves. This is mainly observed by experiencing a “crawling” type sensation on the skin. It can also be observed through twitching of muscles as the nerves get stimulated.
The main reason as to why I have chosen the three topics is due to my desire to learn more about them so that I can acquire more knowledge with regard to their design and application. Firstly, I believe that by acquiring thorough knowledge of the interventional MR system, I would be able to come up with a design capable of producing high-quality images without exposing patients to any bad ionizing radiation as has been witnessed among some radiologists in the past. Understanding better the way of designing and applying the gradient coil is also important to me because this is some of the devices that are responsible for undesirable noise during imaging sequence. Therefore, having a better knowledge of its applicability is critical since its performance has been seen to be critical to the accuracy and speed with which the MR imaging can be generated (MRES 7002-Magnetic Resonance Instrumentation-Mod. 4). The same applies to RF resonators for MR
