They used an MRI machine with a phased array head-neckcoil and a phased array superficial
coil. what are they?
A phased array head and neck coil is a specialized piece of equipment used in MRI scans of the head and neck. It is a radiofrequency (RF) coil that is designed to improve the quality and speed of MRI images by focusing the RF signal to the specific area being scanned.
The coil works by using multiple small antennae that are arranged in an array. Each antenna can receive and send RF signals independently, allowing for better control and manipulation of the signal. This results in improved image quality and faster scan times.
The benefits of using this type of coil include improved image quality, faster scan times, and better signal-to-noise ratio. This can lead to more accurate diagnoses and more efficient scanning processes.
No, it is not necessary for all MRI scans of the head and neck. However, it is commonly used for more complex or detailed scans, such as those for brain tumors or neck injuries. It can also be beneficial for patients who have difficulty remaining still during the scan.
No, there are no known risks or side effects specifically associated with using a phased array head and neck coil. However, as with any MRI procedure, there may be some risks associated with the use of the strong magnetic field and radiofrequency waves. It is important to follow all safety protocols and inform the radiologist of any potential risks or concerns.
