TIC curve
The previously described left parotid mass appears lobulated well-defined of low signal on T1, high signal on T2 with progressive homogeneous enhancement on postcontrast dynamic sequence with no restricted diffusion. A peripheral hypointense rim is noted on T2 sequences representing most likely the fibrous capsule.
The TIC (time signal intensity curve) shows a progressive and gradual enhancement of the tumour (TIC type A according to Yabuuchi et al classification).
