Fig. 1.
Volume of interest (36 voxels of 0.25 cm3 each) centred on an invasive lobular carcinoma in the right breast of a 67-year-old patient and spectral map showing intense water and minor fat peaks in the lesion (a). This array of unsuppressed spectra is shown for the chemical shift range of 0–6 ppm. After application of water and fat suppression intense Cho signals are detected in the whole lesion as shown in green on the metabolic map (b). The highest detected Cho level (the red voxel on the metabolic map) is used for quantification. The sum of all tumour MR spectra together is shown in (c) where the fit for Cho is shown in red (range 2–4.5 ppm)
