- Headaches.
- Hair loss.
- Nausea.
- Vomiting.
- Extreme tiredness (fatigue)
- Hearing loss.
- Skin and scalp changes.
- Trouble with memory and speech.
Does head CT scan have side effects?
Side effects and risks for a cranial CT scan involve discomfort, exposure to radiation, and allergic reaction to the contrast dye. Discuss any concerns with your doctor before the test so you can assess the potential risks and benefits for your medical condition.
Is a head CT a lot of radiation?
Radiation Doses for Common CT Scans Head: 2 mSv, equal to about 8 months of background radiation.
Are there any side effects of a CT scan?
In CT scans, the radiation can cause damage to the cells, which may lead to cancer. CT scans can have 100 to 1,000 times more radiation compared to conventional X-rays. However, the doses of radiation are low, and scans should be done when necessary.
Are there any side effects from head and neck radiation?
Other common side effects from radiation therapy to the head and neck can affect various parts of the body and can have an impact on 25% to 100 percent of patients. The National Cancer Institute has a list of just he oral side effects of head and neck radiation therapy, and they include:
What are the radiation risks from CT procedures?
The probability for absorbed x-rays to induce cancer or heritable mutations leading to genetically associated diseases in offspring is thought to be very small for radiation doses of the magnitude that are associated with CT procedures.
How big is the radiation dose from a CT scan?
The actual dose from a procedure could be two or three times larger or smaller than the estimates. Facilities performing “screening” procedures may adjust the radiation dose used to levels less (by factors such as 1/2 to 1/5 for so called “low dose CT scans”) than those typically used for diagnostic CT procedures.

What are the dangers of X-rays and CT scans?
All of that exposure poses serious health threats. Researchers estimate that at least 2 percent of all future cancers in the U.S.—approximately 29,000 cases and 15,000 deaths per year—will stem from CT scans alone. Even some standard X-rays, which expose you to much smaller amounts of radiation, can pose risks if you undergo multiple ones.
What are the side effects of radiation therapy?
This is a normal side effect and will get better. • After 2 to 3 weeks of treatment, your skin may feel irritated: warm, red, swollen, dry and tight, itchy • In later weeks, areas of your skin may have dry, flaky patches. • Near the end of your treatment, areas of your skin may be open and moist.
