The latest CT technology can effectively reduce radiation

Release date: 2007-07-27

The latest CT technology can effectively reduce radiation. Medical physicist Cynthia H. McCollough uses a new technology to help radiologists control the dose of radiation received by patients. Recently, this technology was explained at the 2007 National Radiation Protection and Measurement Committee meeting, and further pointed out that due to the general lack of knowledge about the radiation and risks of radioactive medical devices in the US public, the media often publishes some confusion about radiation. Report, or create a myth about radiation, such as Spider-Man, or cause the nation to panic about radiation.

An article published in the United States today has caused widespread panic about CT radiation. The article claims that an average of 6 million children who undergo a CT scan of the abdomen or head at the age of 15 will kill 500 of them. This article has caused many patients who have undergone CT testing to experience emotional fluctuations.

McCollough believes that the question should not be "CT is safe" but "whether CT can solve clinical problems", she also introduced a new CT scanner that can display the dose of CT radiation, so that the radiologist can according to different imaging needs Determine the size of the radiation, the amount of radiation can be recorded for each scan, so that they can control the amount of radiation according to the different organs examined. They can also use these parameters to estimate the effective dose to avoid potential biological risks.

Dosimetry can help radiologists accurately use safe radiation doses in different cases. The challenge for doctors is how to ensure that the image is clear enough for diagnosis in the event of a dose reduction.

The new CT scanner's built-in equipment is very powerful in filtering electron beam energy and noise. Doctors can reduce the dose and adjust the image quality by pressing the button or turning the correct dial. For example, the automatic illumination setting can be tailored to the patient's size, and the tube current (MAS) modulator can be used to modulate the radiation dose of the x, y, and z image planes. Based on a stable level of imaging noise level, the new scanner can reduce the radiation dose by approximately 50%. Cardiac CT can also reduce dose by 40% by reducing tube current during cardiac cycle applications.

"We can reduce the dose by 20% on average for patients of different sizes, even for super-obese patients," McCollough said. Patients will increasingly be more inclined to consult a professional who will receive the radiation dose before receiving an imaging diagnosis. “The concept may be too esoteric at the moment, but understanding the effective dose is, on the other hand, a multifaceted trade-off in risk,” she said. “It helps patients make decisions after comparing risks.”
