Figure 6
A 75-year-old female with carcinoma ex 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 0.91 × 10−3 mm2/s and the mean TBF value of 67.96 mL/100 g/min, respectively. On T2-weighted coronal image (d), the lesion shows slightly higher signal intensity compared to muscle structure. Amide proton transfer (APT) (e) map shows the lesion with the mean APT signal intensity of 2.65%. An arrow in each image indicates the lesion.
