Fig. 3From: Quantitative dynamic contrast-enhanced MR imaging can be used to predict the pathologic stages of oral tongue squamous cell carcinomaA 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 0.009Back to article page
