Which risk increases when compressed sensing algorithms reconstruct MRI data?

💡 Explanation

Artifact introduction increases because inaccurate sampling leads to aliasing, where high-frequency signals are misinterpreted as low-frequency signals via the Discrete Fourier Transform. Therefore images will show high frequency artifacts rather than reduce signal to noise.
