Fig. 1. Representative case from development dataset (cyst).

Axial T2-weighted HASTE image (A), ADC map (B), pre- and post-contrast fat-suppressed T1-weighted images (C), and RER map (D) from 70-year-old male patient revealed 3.1 cm mass in anterior mediastinum (arrows). nT2, nADC, and RER values were 0.92, 1.50, and 5.3%, respectively. Pathologic diagnosis after surgical resection was thymic cyst. ADC = apparent diffusion coefficient, HASTE = half-Fourier-acquired single-shot turbo spin echo, nADC = normalized ADC, nT2 = normalized T2 signal intensity, RER = relative enhancement ratio
