TIC and ADC analyses of sinonsal benign and malignant diseases. Axial fat-suppressed T2-weighted images (left), TIC maps (middle), and ADC maps (right). Reference colors for TIC and ADC maps are shown in Fig 1. A, 37-year-old man with organized hematoma in right maxillary sinus. Overall TIC, type 2; overall ADC, 1.20 × 10−3 mm2/s; TIC mapping, 60% type 1, 33% type 2, 6% type 3, 1% type 4, and 0% type 5 areas; ADC mapping, 13% extremely low, 35% low, 40% intermediate, and 12% high ADC areas. B, 76-year-old woman with fungal rhinosinusitis. Overall TIC, type 2; overall ADC, 1.18 × 10−3 mm2/s; TIC mapping, 14% type 1, 44% type 2, 17% type 3, 15% type 4, and 10% type 5 areas; ADC mapping, 17% extremely low, 30% low, 44% intermediate, and 9% high ADC areas. C, 86-year-old man with poorly differentiated SCC in right maxillary sinus. Overall TIC, type 2; overall ADC, 1.04 × 10−3 mm2/s; TIC mapping, 1% type 1, 82% type 2, 16% type 3, 1% type 4, and 0% type 5 areas; ADC mapping, 2% extremely low, 76% low, 20% intermediate, and 2% high ADC areas. D, 66-year-old man with malignant lymphoma (NK/T cell) in left maxillary sinus. Overall TIC, type 3; overall ADC, 0.43 × 10−3 mm2/s; TIC mapping, 1% type 1, 27% type 2, 54% type 3, 17% type 4, and 1% type 5 areas; ADC mapping, 87% extremely low, 13% low, 0% intermediate, and 0% high ADC areas.
