When parameter ↑, what is the effect on spatial resolution (SR), SNR, and acquisition time: signal averages, receiver bandwidth, field strength, partial k-space sampling?

Final answer:

The question addresses the impact of different MRI parameters on spatial resolution, signal-to-noise ratio, and acquisition time. The impacts vary based on whether signal averages, receiver bandwidth, field strength, or partial k-space sampling are modified.

Step-by-step explanation:

The question pertains to the effects of various parameters on spatial resolution (SR), signal-to-noise ratio (SNR), and acquisition time in the context of magnetic resonance imaging (MRI). When signal averages are increased, SNR increases, but at the cost of increased acquisition time; spatial resolution may not be directly affected. Increasing receiver bandwidth generally decreases SNR and can slightly improve spatial resolution while reducing acquisition time. Higher field strength improves SNR and can improve spatial resolution but does not inherently change acquisition time. Partial k-space sampling can decrease acquisition time and potentially reduce spatial resolution, while its effect on SNR depends on the implementation.
