Radiation Exposure and Safety Measures
As mammography technology continues to evolve, ensuring patient safety remains a top priority. Radiation exposure, although minimal, is a crucial aspect of mammography. Here’s what you need to know.
The use of ionizing radiation in mammography is a double-edged sword. While it’s necessary for creating accurate images, excessive exposure can increase the risk of radiation-related side effects. In 2005, researchers at the Mayo Clinic found that mammography can cause a radiation-induced breast cancer in some women. However, numerous studies since then have demonstrated no increased risk for women over 40 in mammograms.
Amount of Radiation Used in Mammography
The amount of radiation used in mammography is surprisingly minimal. A typical mammography uses 0.1-0.3 millisieverts (mSv) of radiation. For comparison, flying in an airplane from New York to Los Angeles exposes you to approximately 0.1 mSv of radiation. To put this into perspective, a mammography uses roughly the same amount of radiation as a standard chest X-ray or a flight from New York to Los Angeles.
Safety Measures Implemented to Minimize Radiation Exposure
To minimize radiation exposure, mammography facilities employ various safety measures. For instance,
- Technologists and doctors are trained to ensure proper positioning and exposure parameters to minimize radiation exposure to patients.
- Screening for calcifications and other abnormalities helps radiologists detect cancers more accurately, reducing the need for repeat imaging and minimizing radiation exposure.
- Compression and exposure adjustments also help keep radiation exposure to a minimum.
- Automated exposure control (AEC) systems help balance the amount of radiation used based on the breast density and thickness, ensuring the optimal image quality while keeping radiation exposure low.
Role of Mammography Technologists in Patient Safety
Mammography technologists play a pivotal role in ensuring patient safety. They’re responsible for positioning patients correctly, ensuring accurate compression, and adjusting exposure parameters to minimize radiation exposure.
Radiation Safety Measures for Patients, Who invented the mammography machine
To ensure patient safety, it’s essential to be aware of radiation safety measures:
- Prior to the mammogram, the technologist will typically review your medical history, including any previous radiation exposure and any health concerns.
