Application of Diffusion Kurtosis Imaging and Histogram Analysis for Assessing Preoperative Stages of Rectal Cancer

Figure 2

Images in a 61-year-old male show T2 stage in pathology. (a) Oblique axis T2WI, the white arrow shows the annular thickening mass of rectum. (b) DKI ( = 2000 s/mm2) shows a high signal of the thickened mass of the rectal wall. (c) ADC map, ADC-10th percentile value is 0.48 × 10−3 mm2/s. (d) Diffusivity map, -10th percentile value is 0.67 × 10−3 mm2/s. (e) Kurtosis map, -10th percentile value is 0.64. (f) The histological specimen shows moderately differentiated rectal adenocarcinoma (HE staining, ×100).
