Predicting of Ki-67 Expression Level Using Diffusion-Weighted and Synthetic Magnetic Resonance Imaging in Invasive Ductal Breast Cancer

Table 5

Diagnostic value of parameters in the low (<30%) or high (≥30%) Ki-67 proliferation groups.

Parameters	Sensitivity (%)	Specificity (%)	AUC	value	95% CI
Pre-T1	38.6	95.0	0.711	<0.001	0.609–0.813
ADC	48.1	82.5	0.637	0.016	0.533–0.732

ADC, apparent diffusion coefficient; AUC, area under curve; CI, confidence interval.
