I have added Gaussian noise on a DICOM image using the following commands..
B=dicomread('image.dcm');
C=imnoise(B,'guassian');
imshow(C);
But it entirely corrupts the image...when I am doing the same for a .jpg file it does not corrupt the whole image...please help me to solve this problem.... Thank you

Try changing the input parameters for imnoise() so that it adds less noise.
Attach your image if you need more help.
