Final answer:
Increasing slice thickness in an MRI scan will lead to an increase in the signal-to-noise ratio (SNR), as a larger volume of signal is captured from the greater amount of tissue included in the thicker slice.
Step-by-step explanation:
The question pertains to the relationship between slice thickness and the signal-to-noise ratio (SNR) in imaging, particularly in the context of magnetic resonance imaging (MRI). When slice thickness is increased, there is a larger volume of tissue being imaged, which means more signal is captured. This leads to an improvement in the SNR. Therefore, increasing slice thickness will increase SNR.
It's important to note that while increasing slice thickness can enhance SNR, it comes with trade-offs. Thicker slices may lead to a loss of spatial resolution and decreased ability to distinguish fine details. The choice of slice thickness should be carefully considered based on the imaging goals and the specific characteristics of the imaging modality.
