The unit mGy*cm (milligray-centimeter) is a measure of radiation dose. It represents the amount of radiation absorbed by the body tissues during a specific medical imaging procedure, such as a CT (computed tomography) scan.
To determine if 352 mGy*cm is considered a lot, we need to compare it to typical radiation doses from other sources and understand the potential risks associated with radiation exposure.
For reference:
- A typical chest X-ray delivers about 0.1-0.5 mGy of radiation dose.
- A typical CT scan of the abdomen or pelvis may deliver 10-20 mGy of radiation dose.
So, 352 mGy*cm is significantly higher than the radiation dose from a single chest X-ray and is considerably higher than a standard CT scan of the abdomen or pelvis.
However, it's important to note that the significance of the radiation dose depends on several factors, such as the area being scanned, the purpose of the scan, and the individual's overall health condition. In some cases, the benefits of obtaining a CT scan to diagnose or monitor a medical condition may outweigh the potential risks associated with radiation exposure.
Radiation doses from medical imaging are typically kept as low as reasonably achievable (ALARA principle) while still providing enough image quality for accurate diagnosis. Medical professionals carefully consider the necessity of the scan and take measures to minimize radiation exposure to the patient.
If you have concerns about the radiation dose from your CT scan, it's essential to discuss them with your healthcare provider. They can provide more context about the specific scan, the reasons for performing it, and address any questions or concerns you may have about radiation safety and risks.
