Objectives.
To differentiate pituitary adenoma from Rathke cleft cyst in magnetic resonance (MR) scan by combing MR image features with texture features.
Methods.
A total number of 133 patients were included in this study, 83 with pituitary adenoma and 50 with Rathke cleft cyst.
Qualitative MR image features and quantitative texture features were evaluated by using the chi-square tests or Mann–Whitney U test.
Binary logistic regression analysis was conducted to investigate their ability as independent predictors.
ROC analysis was conducted subsequently on the independent predictors to assess their practical value in discrimination and was used to investigate the association between two types of features.
Results.
Signal intensity on the contrast-enhanced image was found to be the only significantly different MR image feature between the two lesions.
Two texture features from the contrast-enhanced images (Histo-Skewness and GLCM-Correlation) were found to be the independent predictors in discrimination, of which AUC values were 0.80 and 0.75, respectively.
Besides, the above two texture features (Histo-Skewness and GLCM-Contrast) were suggested to be associated with signal intensity on the contrast-enhanced image.
Conclusion.
Signal intensity on the contrast-enhanced image was the most significant MR image feature in differentiation between pituitary adenoma and Rathke cleft cyst, and texture features also showed promising and practical ability in discrimination.
Moreover, two types of features could be coordinated with each other.
