i wanted to get the mask of only regions in an image with selected intensity values such as 111, 118, 147, etc.... The intensity values can be adjacent values like 91 & 92 or 111 - 115 or random values as given above....
please can someone tell me how to do it....

Assuming a grayscale image:
mask = ismember(yourimage, [91 92 111 118 147]); %obviously adjust the values of the vector to those intensities you want in the mask.
