Clinical Value of Quantitative Parameters of Dynamic Contrast-Enhanced Magnetic Resonance Imaging in Distinguishing Between Benign and Malignant Lesions of the Head and Neck.

=0.354-0.560),achieving the sensitivity of 85.7% and the specificity of 69.4% at a cut-off value of 0.355. Conclusion Among the quantitative parameters of DCE-MRI,Ktrans demonstrates excellent value for differentiating between benign and malignant lesions of the head and neck,serving as a reliable independent predictor and providing critical imaging evidence for preoperative noninvasive evaluation.
