Figure 4
A 68-year-old female with pleomorphic adenoma. (a) T1-weighted image shows a homogeneous low intensity lesion in the left parotid gland. Apparent diffusion coefficient (ADC) (b) and tumor blood flow (TBF) (c) maps show the lesion with the mean ADC value of 1.88 × 10−3 mm2/s and the mean TBF value of 22.55 mL/100 g/min, respectively. On T2-weighted coronal image (d), the lesion shows higher signal intensity than the adjacent parotid gland parenchyma. Amide proton transfer (APT) (e) map shows the lesion with the mean APT-related signal intensity of 0.26%. An arrow in each image indicates the lesion.
