A spine CT scan does involve exposure to ionizing radiation, and compared to some other imaging methods, it generally delivers a higher dose of radiation. However, whether it is considered “high” depends on the context, including the specific area scanned,…
A sinus CT scan involves the use of ionizing radiation to create detailed images of the sinus cavities. The amount of radiation exposure from a sinus CT scan is generally low but higher than that of a standard sinus X-ray…
An abdominal CT scan generally exposes a patient to **more radiation** than a chest CT scan. This difference arises because the abdomen contains a larger volume of tissue and multiple organs that require detailed imaging, which typically necessitates higher radiation…
A PET-CT scan for cancer involves exposure to radiation from two sources: the radioactive tracer used in the PET portion and the X-rays used in the CT portion. The amount of radiation a patient receives depends on several factors, including…
A chest CT scan exposes a person to **significantly more radiation than what they receive from natural background radiation over the course of a year**. To put it simply, the amount of ionizing radiation from a single chest CT scan…
A cardiac CT angiogram (CCTA) is a specialized imaging test that uses X-rays to visualize the coronary arteries and assess for blockages or other heart-related issues. Because it relies on X-ray technology, it involves exposure to ionizing radiation, which is…
Children do generally receive more radiation from a CT scan than adults, but this is not simply because the machine emits more radiation for children. Instead, it is due to several factors related to their smaller size, greater sensitivity to…
A head CT scan for concussion typically involves exposure to ionizing radiation in the range of about **2 to 4 millisieverts (mSv)**. This amount is roughly equivalent to a few months’ worth of natural background radiation that people receive from…
Magnetic Resonance Imaging (MRI) is generally considered safer than Computed Tomography (CT) scans when it comes to radiation exposure because MRI does not use ionizing radiation, whereas CT scans do. This fundamental difference in how the two imaging techniques work…
A full-body CT scan exposes a patient to a significant amount of ionizing radiation, typically ranging from about 10 to 30 millisieverts (mSv), depending on the specific protocols and the machine used. This dose is considerably higher than that of…
