Fig. 3
A well differentiated squamous cell carcinoma in the tongue, T2N2M0 (stage IV). a–c The tumor was seen as a 38 mm × 23 mm × 17 mm mass (arrows) with isointense signal on T1WI (a) and hyperintense signal on T2WI (b), with heterogeneous enhancement on fat-suppressed contrast-enhanced T1WI (c). d DCE-MRI parameters are evaluated by a 3-D VOI (arrow). e–h Pseudocolorized maps show individual parameters derived from DCE-MRI. The measured Ktrans (e) is 0.043 min−1, Kep (f) is 0.503 min−1, Ve (g) is 0.090, and Vp (h) is 0.009
