Abstract
Computed tomography (CT) is a modern examination method whose radiation characteristics vary depending on the population groups, the part of the body being examined, and other implementation conditions. The use of CT has become increasingly widespread. However, there is a growing concern regarding the harm caused by CT radiation. The opinions regarding whether low-dose CT can induce cancer differ. It is necessary to consider the research population, radiation characteristics, and different parts of the body being exposed to radiation before the application of radiation to ensure the knowledge used is scientifically sound and reasonable. Therefore, different studies have different opinions on whether low-dose CT induces cancer, and not all physicians are aware of this. The present review article aimed to impart relevant insights and a correct understanding of the hazardous effects of low-dose CT radiation on the human body and help physicians reduce unnecessary CT radiation exposure.
