What is one consequence of an increase in echo spacing when using lower receiver bandwidth?

An increase in echo spacing combined with a lower receiver bandwidth leads to more blurring in MRI images. This occurs because a lower receiver bandwidth results in longer echo times, making the images more susceptible to motion artifacts and blurring. In MRI, higher resolution is generally achieved with higher bandwidth, as this allows for shorter echo times and better sampling of spatial frequencies. Consequently, when echo spacing increases due to lower receiver bandwidth, individual signals from different areas of the anatomy might overlap more prominently, leading to a reduction in image clarity and the manifestation of blurring.

The options that suggest improved spatial resolution, increased coverage of anatomy, or reduced susceptibility artifacts do not align with the implications of these technical parameters. In fact, a lower receiver bandwidth typically narrows the frequency range of the received signals, which can exacerbate issues with blurring rather than improving image quality or coverage.
