Fig. 2E —MRI of SCCVII (squamous cell carcinoma) tumors. From left to
right, images are unenhanced T1-weighted, contrast-enhanced T1-weighted, and
T2-weighted. Images after application of continuous-wave HIFU. Unenhanced
T1-weighted image is D; no contrast material uptake (arrow) on
contrast-enhanced T1-weighted image (E) was seen as sign of
devascularization. On T2-weighted image (F), treated tissue shows
higher signal intensity (arrow).
