Fig. 2From: 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, T1N0M0 (stage I). a–c The tumor was seen as a 20 mm × 12 mm × 11 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 volume of interest (arrow). e–h Pseudocolorized maps show individual parameters derived from DCE-MRI. The measured Ktrans (e) is 0.125 min−1, Kep (f) is 0.995 min−1, Ve (g) is 0.127, and Vp (h) is 0.054Back to article page
