Advanced magnetic resonance imaging findings in salivary gland tumors

Figure 4 Sixty-one years old male patient with non-Hodgkin lymphoma infiltrating into the right parotid gland. A and B: Hypointense signal of the lesion compared to the gland on T2-weighted image and T1-weighted image; C: Contrast enhancement components of different intensities are seen on contrast-enhanced image in the lesion; D: The apparent diffusion coefficient (ADC) value of mass was 0.55 × 10^-3 mm²/s on the ADC map; E: The mass is hyperperfused on the color-coded perfusion image; F: The time intensity curve of mass has a wash-out ratio of 43%.
