Fig. 1A. —36-year-old man with carcinoma of oral tongue classified as
T2. Patient underwent radiation with total dose of 39.6 Gy. T2-weighted MR
image obtained after irradiation shows lesion (arrows) to be slightly
hypointense compared with signal intensity of contralateral side.

Fig. 1C. —36-year-old man with carcinoma of oral tongue classified as
T2. Patient underwent radiation with total dose of 39.6 Gy. Contrast-enhanced
MR image shows same degree of enhancement of tumor (arrows) as
salivary glands.

Fig. 1D. —36-year-old man with carcinoma of oral tongue classified as
T2. Patient underwent radiation with total dose of 39.6 Gy.
Time—intensity curve derived from dynamic MR image shows maximal
enhancement of tumor 54-81 sec after infusion of contrast material. 1 = tumor,
2 = contralateral side of tumor, 3 = digastric muscle.

Fig. 2A. —48-year-old man with carcinoma of oral tongue classified as
T3. Patient underwent radiation with total dose of 39.6 Gy. T2-weighted MR
image after irradiation shows lesion (arrows) to be hyperintense
compared with signal intensity of contralateral side.
