Figure 3.

A) DW image of a patient with peritoneal metastasis at b 1000 gradient. Peritoneal metastasis is demonstrated with increased signal intensity (arrows) in comparison to surrounding tissues. One ROI (7) is inserted within the metastasis while the other three ROIs (5, 6, 8) are inserted in the surrounding fat to measure the ADC values on the corresponding ADC map. B) On an ADC map, the green colored area represents metastasis and restricted diffusion (ROI 7). The mean ADC value of peritoneal fat around a metastasis is 2.01×10−3 mm2/s. C) The peritoneal fat in a patient in group II is seen as being hypointense on a DW image at b 1000 gradient. D) On an ADC map, the mean ADC value of normal peritoneum in a patient without malignancy reveals the ADC value as 1.98×10−3 mm2/s.
