Magnetic Resonance Instrumentation

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 ...Show more

Summary

This is achieved by increasing using multiple turns of the coil to increase its sensitivity, to allow high duty of pulsing. At the same time, the design will consider the…

Functional magnetic resonance imaging
Functional magnetic resonance imaging or fMRI is a process of mapping brain activities by analysing the modifications in blood flow and oxygenation levels that vary according to neural activities taking place within the brain (Huettel, Song and McCarthy, 2009).

Magnetic Resonance Imaging (MRI)
Figure 1 shows an example of an MRI image from a moving patient. In such cases, use of sedation or general anesthesia is warranted to increase tolerance to an unpleasant but necessary procedure, and to expedite MRI imaging of a distressed patient (Medical Advisory Secretariat, 2003; Shellock, 2011).

Breast Magnetic Resonance
Magnetic resonance Imaging involves the use of powerful magnetic fields and radio frequencies to produce computerized and detailed images of soft tissues, organs and bones, as well as any other internal body structure. Unlike some imaging techniques, such as X-ray or computed tomography, MRI does not require the use of ionizing radiation.

Peer Review: Magetic Resonance Instrumentation: Phased Array Coils - Pros and Cons
As one of the major types of radio frequency (RF) coils, phased array coils offer several distinct advances to MRI technologies. Those include increased signal to noise (SNR) ratios for improved image quality; the ability to do parallel imaging faster and/or with improved image quality; and reduced scan times in general.
