This is fundamental in radiological practice where comparison with previous imaging can offer critical insights into the progression or regression of a potential disease, ensuring accurate examination and diagnosis. This preventive measure is part of the wider workflow in radiography, which includes tests like mammograms and MRI scans, providing invaluable data for disease diagnosis and aiding in the early detection of conditions such as breast cancer.
