When Noise Misleads: Understanding the Impact of Correlated Noise on Quantitative Image Quality Metrics in MRI
Impact: While IQMs
are commonly used to determine the superiority of image acquisition or
reconstruction methods, differing conclusions about whether noise correlation
decreases quality exemplifies why one should be cautious when using IQMs as indicators of technical performance.
