A single CT scan accounts for a mean dose of eight milligrays, which is related to bone marrow harm. The researchers discovered that a number of CT scans or accumulation of radiation to 100 milligrays triples the chance of creating blood most cancers.

“The exposure associated with CT scans is considered low, but it is still higher than for other diagnostic procedures,” mentioned Elisabeth Cardis, a research writer. “The procedure must be properly justified – taking into account possible alternatives – and optimized to ensure that doses are kept as low as possible while maintaining good image quality for the diagnosis.”
