Both mri scans and CT scans are important tools used by a doctor to facilitate accurate
diagnoses of serious illnesses such as heart disease and cancer. When used in imaging in oncology, these modalities are particularly vital. By combining scanned images over time they allow information to be obtained such as how much the cancerous cells have spread and at what rate they are growing. This means patients can receive updates on whether their treatment is working and whether the cancer shrinking rather than growing in size. PET CT software in particular is vital for providing valuable oncological information such as this. Very different but equally as important as one another, CT scans, and MRI scans as well, play an important role in modern medicine.
