Sixty-nine patients with gastric cancer underwent
preoperative diffusion-weighted MRI and surgical
resection. Mean and min ADC values of each gastric
cancer as well as normal gastric walls were obtained.
Meanwhile, histologic type, differentiation degree and
Lauren classification of each resected specimen were
determined. There were significant differences of mean
and min ADC values among gastric cancers with different
histologic types, differentiation degrees and Lauren
classifications. Mean and min ADC values correlated with
histologic differentiation and Lauren classification
significantly. We concluded the ADC values may be
helpful in evaluating gastric cancers histologic
features, such as histologic types, differentiation
degrees and Lauren.
