Question

Decreasing the receive bandwidth will have which of the following effects?

1) Increased SNR, increased readout time, increased metal artifact and chemical shift artifact of the 1st kind
2) Decreased SNR, increased readout time, increased metal artifact and chemical shift artifact of the 1st kind
3) Increased SNR, decreased readout time, increased metal artifact and chemical shift artifact of the 1st kind
4) Increased SNR, increased readout time, decreased metal artifact and chemical shift artifact of the 1st kind

Answer 1

Decreasing the receive bandwidth will result in decreased SNR, increased readout time, and increased metal and chemical shift artifacts of the 1st kind.

Step-by-step explanation:

Decreasing the receive bandwidth will have the following effects:

1. Decreased SNR: Decreasing the receive bandwidth reduces the signal-to-noise ratio (SNR), which means the signal strength becomes weaker compared to the noise level.
2. Increased readout time: Decreasing the receive bandwidth can lead to longer readout times because it takes more time to process and interpret the weaker signal.
3. Increased metal artifact and chemical shift artifact of the 1st kind: Metal artifacts and chemical shift artifacts of the 1st kind can become more prominent when the receive bandwidth is decreased.
