What advantage do phased array coils provide in MRI imaging?

Phased array coils offer a larger field of view (FOV) in MRI imaging due to their design and ability to collect data from multiple areas simultaneously. These coils consist of multiple smaller coil elements that are strategically positioned around the region of interest. This configuration allows for more efficient signal detection and enhances coverage of the anatomy being scanned.

When utilizing a phased array coil, the overlapping of individual coil signals enables improved signal-to-noise ratios and the acquisition of high-quality images over a wider region. Because of the way that these coils are designed, they can effectively target and capture signals from a vast area, resulting in a larger field of view compared to traditional single-coil systems.

The other choices, while relevant to various aspects of MRI imaging, do not specifically highlight a characteristic or direct benefit of phased array coils. For instance, patient comfort primarily relates to the design and physical interaction of the patient with the MRI machine, rather than the technical capabilities of the coils themselves. Additionally, some noise artifacts might be influenced by other factors rather than solely by the type of coil used. Cost-effectiveness can vary widely based on technology, usage, and specific healthcare settings but is not a direct feature tied to the capabilities of phased array coils.
