まとめ
人工知能(AI)は心筋梗塞(MI)の心エコー検査の解釈において有望視されているが、現在の視覚的な説明は、臨床医のパフォーマンスを向上させるどころか、妨げる可能性がある。将来のAI統合には、臨床推論と一致する説明が必要である。
科学分野:
- 心臓病学; 人工知能; 医用画像処理
背景:
- 心エコー検査は心筋梗塞(MI)の評価に不可欠ですが、観察者間のばらつきがあります。; 人工知能(AI)は自動解釈の可能性を提供しますが、人間とAIの協調への影響については研究が必要です。
研究 の 目的:
- MIの心エコー検査を解釈する心臓病学研修医の診断パフォーマンスに対するAI駆動型説明の影響を評価すること。
主な方法:
- MIを心エコービデオから検出するためにResNet18-LSTMモデルをトレーニングしました。; Gradient-weighted Class Activation Mapping(Grad-CAM)を使用して視覚的な説明を生成しました。; 心臓病学研修医の診断パフォーマンスを、エコークリップ単独、AI予測との併用、AI予測とGrad-CAM説明との併用の3つの条件で比較しました。
主要な成果:
- AIモデルは高い識別性能(AUC 0.9250–0.9429)を達成しました。; AI単独(正解率80.0%)は、臨床医単独(正解率77.0%)をわずかに上回りました。; AIと人間の判断を組み合わせてもパフォーマンスは向上せず、視覚的な説明により正解率は72%、特異度は83.8%に低下しました。
結論:
- AIは心エコー検査でMIを検出できますが、現在の説明可能性手法は臨床推論と一致しない可能性があります。; 説明可能なAI技術は、臨床ワークフローと一致しない場合、診断パフォーマンスを低下させる可能性があります。; 将来のAI統合には、臨床医の専門知識を妨げるのではなく、補完する説明戦略が必要です。

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Uncertainty in Measurement: Accuracy and Precision
100.8K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
