Fig. 6
Examples of DW images and ADC maps in body tumours. From left to right: non-DW image (b = 0); DW image; ADC map. A 37-year-old breast cancer female patient, presenting with a liver metastasis, was scanned on a 3 T GE SIGNA Pioneer system. B 70-year-old prostate cancer male patient, presenting with disseminated bone metastases. The figure demonstrates the unique ability of DWI to highlight between- and within-tumour contrasts, e.g., intense DW signal attenuation (and hence high ADC) in the core of the breast cancer liver metastasis, compatible with the presence of a tumour necrotic core.
