Axial images obtained in a 57-year-old man with marginal zone B-cell lymphoma of the right orbit.
A, T2-weighted fat-suppressed MR image shows the mass (arrows).
B, LSDWI obtained with b = 1000 s/mm2 shows the mass (arrows).
C, ADC map shows that the signal intensity of the mass (arrows) is slightly lower than that of normal brain parenchyma. ADC of the mass is 0.59 × 10−3 mm2/s.
