From: Evaluation of functional magnetic resonance APT and DKI imaging for breast cancer
ROC curves of each quantitative parameter on ER (A), PR (B), HER2 (C), and lymph node metastasis status (D). (A) AUC (Kapp) = 0.695, AUC (Dapp) = 0.690, AUC (APT) = 0.541, and AUC (ADC) = 0.677. (B) AUC (Kapp) = 0.651, AUC (Dapp) = 0.638, AUC (APT) = 0.524, and AUC (ADC) = 0.665. (C) AUC (Kapp) = 0.650, AUC (Dapp) = 0.650, AUC (APT) = 0.645, and AUC (ADC) = 0.699. (D) AUC (Kapp) = 0.596, AUC (Dapp) = 0.546, AUC (APT) = 0.508, and AUC (ADC) = 0.629. No considerable difference in AUCs of other parameters and methods was noted. ADC, apparent diffusion coefficient; APT, amide proton transfer; AUC, area under the curve; Dapp, apparent diffusivity; DKI, diffusion kurtosis imaging; Kapp, apparent kurtosis coefficient
