Comparison of some statistical measurements extracted from benign, malignant and normal MRI brain images

الملخص EN

People may believe that tissue of normal brain and brain with benign tumor have the same statistical descriptive measurements that are significantly different from the of brain with malignant tumor.

Thirty brain tumor images were collected from thirty patients with different complains (10 normal brain images, 10 images with benign brain tumor and 10 images with malignant brain tumor).

Pixel intensities are significantly different for all three types of images and the F-test was measured and found equal to 25.55 with p-value less than 0.0001.

The means of standard deviations and coefficients of variation showed that pixel intensities from normal and benign tumors images are almost have the same behavior whereas they were significantly different from images of malignant brain tumors with F-tests equal to 23.22 and 6.51 respectively with corresponding p-values of 0.00001 and 0.005 respectively.
