Comparison of Some Statistical Measurements Extracted From Benign, Malignant and Normal MRI Brain Images

Abstract

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.
