[Abstract] Objective: To investigate the diagnostic value of 3.0 T magnetic resonance imaging (T2WI) grayscale histogram texture features in solid pancreatic lesions.Materials and Methods: The clinical and MRI imaging data of 117 patients with solid pancreatic mass were retrospectively analyzed, 69 cases of ductal adenocarcinoma, 12 cases of solid pseudopapillary, 15 cases of neuroendocrine tumor and 21 cases of mass pancreatitis were confirmed by surgical pathology. They were divided into malignant tumor group (ductal adenocarcinoma), benign to low-grade malignant tumor group (solid pseudopapilloma and neuroendocrine tumor), and non-tumor group (mass pancreatitis). The region of interest (ROI) was delineated at the maximum lesion on T2WI sequence using GE Omni-kinetics software and automatically generate grayscale texture parameters of straight, comparison between the 3 groups using one-way analysis of variance (ANOVA), Pairwise comparisons between groups were made by LSD-t-test (homogeneity of variance) or by Kruskal-walls test of multiple independent samples (heterogeneity of variance). Parameters with a statistical difference were screened, and the ROC curve was drawn to evaluate the efficacy of differential diagnosis of solid pancreatic lesions.Results: Mean, Variance, Energy, Entropy, 5th percentile, 10th percentile, 25th percentile, 50th percentile, 75th percentile, 90th percentile, and 95th percentile were statistically significant (all P<0.05). There was no statistical difference in skewness and kurtosis between the three groups (all P>0.05). The sensitivity of variance to differentiate PDAC and MFCP was 82.6%, the specificity was 85.7%, the area under the curve was 0.899, and the best cut-off value was 5915.87. The sensitivity of mean to differentiate PDAC and SPT+pNET was 64.4%, the specificity was 87.0% and the area under the curve was 0.688, the cut-off was 1113.55. The sensitivity of 90th percentile to differentiate MFCP and SPT+pNET was 88.9%, the specificity was 85.7% and the area under the curve was 0.924, the cut-off was 837.59. They had a high identification efficiency.Conclusions: There are significant differences in the texture parameters of the T2WI histogram between solid pancreatic lesions. Mean and Percentile have significant clinical value in the qualitative and benign or malignant differentiation of solid pancreatic lesions.
