Application of Diffusion Kurtosis Imaging and Histogram Analysis for Assessing Preoperative Stages of Rectal Cancer
Images in a 65-year-old male show T2 stage in pathology. (a) Oblique axis T2WI, the white arrow shows the thickened rectal wall. (b) DKI shows a high signal of the thickened rectal wall. (c) ADC map, ADC-10th percentile value is 0.52 × 10−3 mm2/s. (d) Diffusivity map, -10th percentile value is 0.72 × 10−3 mm2/s. (e) Kurtosis map, -10th percentile value is 0.54. (f) The histological specimen shows moderately differentiated rectal adenocarcinoma (HE staining, ×40).
