The most common side effects are due to the contrast dye, exposure to radiation, and very rarely kidney problems. CT scans are typically performed with low radiation doses, so the risk of cancer in reality remains very low, but is still a consideration for people who have a number of CT scans.
Side Effects Of CT Scan
Some individuals may have allergies to the contrast materials. Most reactions may be mild, resulting in itchiness or rash but there is always the potential for a life-threatening reaction in rare cases. This is why your health care provider may want to watch you for a short time after your CT scan. Be sure to tell your doctor about any and all allergies to medications, seafood, or iodine. Your doctor should also be aware if you have diabetes and take the medication metformin. They will advise you on whether you need to discontinue your medication before or after your procedure.
Radiation
CT scans use ionizing radiation. While high doses of ionizing radiation can potentially increase cancer risk, the radiation dose from a single CT scan is very low. The risk is thought to be extremely low – it has been estimated that the likelihood of dying from a cancer diagnosis as a result of a CT scan is 1 in 2,000.
Contrast Material Reactions
If your CT scan does need contrast material, there is a minor risk of an allergic reaction. Most reactions are minor, producing symptoms such as itchiness or a rash. Some individuals might get side effects from the contrast material, such as.
Incidental Findings
It is not unusual for CT scans to detect abnormalities that have nothing to do with the initial indication for the scan. Although these “incidental findings” may, on occasion, result in early identification of significant disease, they can also result in substantial additional clinical workup that will necessitate long-term follow-up.
Kidney Issues
In the unlikely event, the contrast material injected in CT scans can impair kidney function in individuals with pre-existing kidney disease or diabetes.Your physician will assess kidney function prior to the use of contrast material if suspicion exists.
Pregnancy
If pregnant or suspect that you are pregnant, it is advisable to notify your physician prior to having a CT scan. Although radiation from a head CT is not expected to harm a fetus, the physician will advise you whether an alternative imaging method should be used, such as ultrasound or MRI.
Children
Children are more sensitive to the effects of radiation than adults, and therefore, particular care must be taken when conducting CT scans on pediatric patients. The settings of the CT machine are such that the lowest possible amount of radiation is utilized while still getting the required images.
Minimizing Side Effects
To reduce the side effects that may occur with CT scans:
- Have CT scans only when medically indicated.
- If you’re expecting or suspect that you are, let your health care provider know.
- In children, ask if the CT settings were modified for pediatric use.
Conclusion
An open discussion with your doctor regarding the need and possible complications of a CT scan is essential. For most individuals, the advantages of imaging diagnosis by a medically necessary CT scan are more than the rare risk of side effects. Informed about any allergies, medical disorders, pregnancy, or previous sensitivity to contrast medium at all times, inform your physician so protective measures are taken to safeguard you.
Frequently Asked Questions
Q. What is the Full form of CT scan?
CT scan stands for Computed Tomography scan.
Q. Is CT scan safe?
CT scans are safe and involve some ionizing radiation which can be harmful if performed on some. So let a doctor consult the scan and speak with a radiologist or official.
Q. Is CT scan noisy?
CT scan doesn’t have noises, there’s just a tiny noise which is not loud or annoying.
Q. What is a CT scan test for?
CT scan is used to find tumours, fractures, infections, and internal injury.
Q. Are imaging centers cheaper than hospitals?
Yes, imaging centres have no room and other charges and so are a little cheaper than private hospitals. If you want to find the cheapest imaging centres near you call carebox.
