What is the effect of increasing the receiving bandwidth during an MRI scan?

Increasing the receiving bandwidth during an MRI scan primarily reduces artifacts. A wider bandwidth allows for a greater range of frequencies to be sampled, which can help in minimizing certain types of image artifacts, such as chemical shift artifacts and minimize the effects of magnetic field inhomogeneities.

When the bandwidth is increased, the system is less sensitive to high-frequency noise and variations in the magnetic field, which helps achieve clearer images with fewer distortions. This process is especially critical in complex imaging scenarios where precise delineation of anatomy or pathology is necessary.

While increasing the bandwidth does affect other aspects of the imaging process, such as the signal-to-noise ratio and spatial resolution, its primary effect in the context of artifacts is significantly advantageous in improving image quality and diagnostic reliability. The correct response reflects the important principle that managing bandwidth is essential for optimal MRI results and reducing any interference that could obscure the diagnostic information.
