Differentiation of Pituitary Adenoma from Rathke Cleft Cyst: Combining MR Image Features with Texture Features

Table 6

The results of the receiver operating characteristics curve for relationship between MR image feature (signal intensity on the contrast-enhanced image) and texture features from the contrast-enhanced image.

Texture features	value	AUC	Standard error	95% CI	Cutoff point	Sensitivity	Specificity
Contrast-enhanced image
Histo-Skewness	<0.0001	0.85	0.050	0.768∼0.911	1.005	93.33	72.73
GLCM-Correlation	<0.0001	0.74	0.059	0.649∼0.822	0.450	85.33	68.75

Histo, histogram-based matrix; GLCM, grey-level co-occurrence matrix; AUC, area under the curve; CI, confidence interval.
