Figure 1

A 44-year-female patient with right lobe thyroid adenoma; (A-C) Non-contrast and contrast transversal images showed a hemorrhage in the right lobe (short thick arrow). Long thin arrow shows the lesion. ( D ) Coronal images showed the well-circumscribed lesion with homogenous enhancement. ( E-G ) showed ADC value obtained from ADC map with b factors of 0, 300, 500 and 800 s/mm², respectively. ROIs were placed in the lesion at right upper area to avoid the hemorrhage area. ( H ) ADC map generated at b-factor of 300 s/mm².
