Thirty-four-year-old woman presenting with an enhancing suspicious mass in the early contrast enhanced subtraction image (a). b presents the water resonance peak at 4.74 ppm in the unsuppressed water reference spectrum (blue bar), weaker resonance peaks can be depicted at 3.23 (corresponding to total Choline tCho) and 1.3 and 0.9 ppm (methylene and methyl groups from lipids). The magnified water suppressed spectrum reveals the distinct tCho resonance peak at 3.23 ppm (gray bar). Using water as an internal reference, tCho was calculated as 13 mmol/l. Histopathology revealed an invasive ductal cancer NST G3 with ipsilateral lymph node metastases
