- Are There Any Risks?
- CT scans use X-rays, which produce ionizing radiation.
- Research shows that this kind of radiation may damage your DNA and lead to cancer.
- But the risk is still very small — your chances of developing a fatal cancer because of a CT scan are about 1 in 2,000.

Is a CT scan better with or without contrast?
Please remove all piercings and leave all jewelry and valuables at home. CONTRAST MEDIA: CT scans are most frequently done with and without a contrast media.

Why would a doctor order a CT scan instead of an MRI?
A CT scan may be recommended if a patient can’t have an MRI. People with metal implants, pacemakers or other implanted devices shouldn’t have an MRI due to the powerful magnet inside the machine. CT scans create images of bones and soft tissues.
Why would a cat scan be ordered?
CT scans can detect bone and joint problems, like complex bone fractures and tumors. If you have a condition like cancer, heart disease, emphysema, or liver masses, CT scans can spot it or help doctors see any changes. They show internal injuries and bleeding, such as those caused by a car accident.
Which is worse MRI or CT scan?
CT scans are more widely used than MRIs and are typically less expensive. MRIs, however, are thought to be superior in regards to the detail of the image.
What diseases can a CT scan detect?
Things that a CT scan can find include:
- Certain types of cancer and benign (noncancerous) tumors.
- Fractures (broken bones).
- Heart disease.
- Blood clots.
- Bowel disorders (blockages, Crohn’s disease).
- Brain and spinal cord diseases or injuries.
- Internal bleeding.
How long does it take to get CAT scan results?
Most scans take just a few minutes. The whole thing takes about 90 minutes and you usually get the results within a couple of weeks.
