Figure 1

(A,C) Proton density-weighted MR images of two representative xenografts two (A) and three (C) weeks after cell inoculation, respectively. Scale bars=10 mm. (B) 1H MRS spectrum from tumour in A. The selected VOI is indicated by a rectangle. Cho-containing compounds dominate the spectrum. ML signals are also seen. TE=20 ms, 128 averages. (D) 1H MRS spectrum from large tumour seen in C. The VOI (rectangle in C) includes tumour tissue with variable signal intensity. There is a weak Cho signal while MLs dominate. TE=20 ms, 128 averages. B and D are not shown to scale.
