Frequently Asked Questions
How do contrast-to-tumor (CT) scan be a bit separate from positron emission tomography (PET) scans?
An X-ray of CT produces detailed images and a PET detects metabolic activity when using a radioactive tracer which some diseases like cancer it can be identified.
Are CT and PET scans concerning safety?
They are usually deemed safe and are conducted by competent professionals. CT scans contribute a small amount of radiation, but only PET scans pose a risk from radioactive tracing agents.
What is expected from me if I am going for a CT or PET scan?

CT scans only require several minutes, but for PET examinations 30-45 minutes need to be devoted to the scanning of the area and the preparation.
What types of conditions can CAT and PET scans detect?
CT scans allow better visualization of anatomical structures than PET scans, which are very useful in detecting unhealthy cell growth in cancer. Furthermore, they can be used to evaluate cancer and detect metabolic changes in different conditions.
