Figure 4

Reconstructed 2D COSY spectra from malignant lesions identified in 41-year-old patient (grade 3 invasive ductal carcinoma and ductal carcinoma in situ, estrogen receptor positive, progesterone receptor positive, her2 positive, ki-67 = 60% and BI-RADS 5): (a) FFT based spectrum, (b) FFT based spectrum after zero-filling along t1, (c) CT based spectrum, (d) IP based spectrum, (e) T2-weighted MR image with the white box representing the VOI placement. Red square shows the location of extracted spectrum. Arrows 1 and 2 show\ the effect of t1-ridging in (a, b).
