F28, healthy control with bilateral non-metastatic RLNs. Axial T2WI (a) shows bilateral RLNs (curved arrows) with heterogeneous slightly high signal intensity and size as long axis × short axis of 5 × 4 mm (right) and 7 × 5 mm (left), respectively. Both lymph nodes showed slightly higher perfusion compared with the surrounding tissue on the fused image by ASL and T2WI (b), with a BF value of 42.5 mL/100 g/min and 32.14 mL/100 g/min. ROI of the lymph nodes was delineated on the multi-b-value DWI with b value = 800 s/mm2 (c), acquiring at ADC value of 0.993 × 10−3 mm2/s and 0.874 × 10−3 mm2/s on ADC map (d), respectively
