Using a mask with a Different matrix size as target image to obtain image

I have a known Mask as a 240x240 Double. I usually use this mask against the same matrix size image but I need a way to convert this to use it against an image with a matrix size 448x448 uint16.
The code i usually use is
T2FS=dicomread(T2FSa{1});
T2FS(~mask)=NaN;
imagesc(T2FS); %shows the mask
avgSig=mean(T2FS(mask));
but the mask and the image T2FS aren't the same image matrix size. Any help would be greatly appreciated.

So where in the larger image do you want to place your mask? Or do you want to scale it with imresize() so that it's the same size as your image?
