A CT scan and a PET scan are both medical imaging techniques that use radiation, but they differ in how much radiation they expose the patient to and what kind of information they provide. When considering safety, especially regarding radiation…
Determining how many CT scans are safe to have in a year depends on balancing the medical benefits of the scan against the risks associated with radiation exposure. CT scans use ionizing radiation, which can increase lifetime cancer risk, but…
A low-dose lung CT scan typically exposes a patient to radiation in the range of about 1.3 to 3.4 millisieverts (mSv). This amount is significantly lower than that of a standard diagnostic chest CT, which can range from approximately 8.5…
A single CT scan does expose the body to ionizing radiation, which has the potential to increase cancer risk, but the risk from just one scan is generally considered very low. The amount of radiation from a typical CT scan…
A dental cone beam CT (CBCT) scan exposes a patient to a small amount of radiation, more than a single traditional dental X-ray but significantly less than a conventional medical CT scan. Typically, the radiation dose from one CBCT scan…
A CT scan generally exposes a person to **significantly more radiation** than a mammogram. To understand why, it helps to look at what each procedure involves and how much radiation they typically use. A **mammogram** is a specialized X-ray of…
A typical CT scan of the brain exposes a person to ionizing radiation in the range of about **20 to 60 milligray (mGy)** absorbed dose, with an equivalent effective dose usually estimated around **2 to 4 millisieverts (mSv)**. This amount…
A CT scan of the abdomen and pelvis exposes a person to ionizing radiation typically in the range of about **10 to 16 millisieverts (mSv)**, depending on the specific protocol and whether contrast dye is used. This level of radiation…
A chest CT scan involves using X-rays to create detailed cross-sectional images of the chest, including the lungs, heart, blood vessels, and bones. Because it uses ionizing radiation, many people wonder if it is dangerous due to radiation exposure. The…
A chest CT scan exposes a person to significantly more radiation than a standard chest X-ray. Typically, a single chest X-ray delivers about 0.1 millisieverts (mSv) of radiation, which is roughly equivalent to the natural background radiation you would receive…
