Increasing the field of view (FOV) in MRI significantly enhances the signal-to-noise ratio (SNR). A larger FOV allows for a greater volume of tissue to be included in the imaging, which leads to more received signals from the tissue being sampled. This increase in the number of signals improves the overall SNR, resulting in clearer and more detailed images. Enhanced SNR is crucial in MRI because it directly affects the quality of the images produced, making it easier to visualize anatomical structures and detect abnormalities.

Other options, while related to MRI imaging, do not provide the same benefit associated with increasing the FOV. For example, increasing the FOV can actually lead to decreased spatial resolution because larger FOVs require more significant pixel sizes for the image layout, which can limit the detail seen in smaller structures. Additionally, a larger FOV may result in more anatomical coverage, rather than less. Lastly, increasing the scan time might be a consideration with larger FOVs, but the primary benefit lies in the increased SNR, enhancing image quality without necessarily prolonging the duration of the scan as a definitive outcome.
