Comparison of the impact of rectal susceptibility artifacts in prostate magnetic resonance imaging on subjective evaluation and deep learning: a two-center retrospective study.

Summary: Imagine trying to take a clear photograph through a foggy window; the details get lost. A similar problem happens in medical imaging when gas or air in the rectum creates visual distortions, known as "artifacts," on prostate MRIs. A new study involving over 1,000 patients investigated whether these blurry spots confuse Artificial Intelligence (AI) or human doctors more.

The results showed that both junior radiologists and advanced AI models struggled significantly when these artifacts were present, leading to a drop in cancer detection accuracy. Interestingly, the AI had a harder time regardless of whether the distortion was in the center or the edge of the prostate. This suggests that for AI to be a reliable partner in diagnosing prostate cancer, we must ensure the images are "clean" and free of these interference patterns first.
