A method of processing images

An image-processing system comprising a computing device having at least one processor, the image processing system being configured to:

• obtain a first cross-sectional post contrast image of at least part of a body, the first cross-sectional post contrast image representing a first time point;
• obtain a second cross-sectional post contrast image of the at least part of the body, the second cross-sectional post contrast image representing a second time point, the second time point being different from the first time point;
• and
• generate a first difference image using the first and second cross-sectional post contrast images, the first difference image highlighting any differences between the first and second cross-sectional post contrast images.

A computer-readable medium having computer executable code for

• obtaining a first cross-sectional post contrast image of at least part of a body, the first cross-sectional post contrast image representing a first time point;
• obtaining a second cross-sectional post contrast image of the at least part of the body, the second cross-sectional post contrast image representing a second time point, the second time point being different from the first time point;
• and
• generating a first difference image using the first and second cross-sectional post contrast images, the first difference image highlighting any differences between the first and second cross-sectional post contrast images.
