Are the doctors using excessively using computed tomography? CT Or more than 90 million times in 2023. According to a study just published ZaemagiAnd April 14, 2025. The name of the cat scan is harmless, but it actually represents ionized radiation similar to X-ray. According to the researchers, the CT scan will lead to more than 100,000 future cancer. Don’t understand it wrong though. Such imaging is absolutely essential. But this study raises important questions. Is the proposed CT scan absolutely needed or “if” is an additional test? What question should I ask ~ Before Is there a CT image?
How CT Images have gained popularity:
In 1980, there was 3 million CT scans. Harvard Health Publishing.
Research paper Archive Post On December 14, 2009, it reported:
“The use of computed tomography (CT) scans in the US (US) has more than three times since 1993, recording about 70 million scans every year.”
In 2023, 66 million Americans received 93 million scans. Obviously, the CT test was very popular in 21.castle century. Do they all need?
When scanning CT Be essential:
There are many situations when scanning CT Be critical. If an emergency room is suspected of bleeding (bleeding) stroke, a quick diagnosis must be a computed tomography of the head. Such scans are also excellent for detecting appendicitis, intestinal obstruction, amphemolia (lungs), kidney stones and lungs or colon cancer.
Have you ever scanned CT? Is it an essential or “if” scan to rule out serious things? This imaging can be very helpful only If it’s worth dangerous.
My personal experience of important CT image:
The value of this diagnostic tool can be said in experience. A few years ago, I had an amazing abdominal pain during a flight from California to North Carolina. The pain was too bad during the flight, so I asked the crew to ask for an emergency landing.
Still, I made it hard, and when we arrived home, a friend of gastrointestinal diseases headed straight to the emergency room of the nearest hospital. In a few minutes, I was scanning my abdomen. The diagnosis was Intussusception. My small intestine slipped into the intestines and caused the intestinal closure. I saved me for emergency abdominal surgery.
CT imaging is increasing!
December 14, 2009 scientists Zaemagi.
Background of computer tomography scan:
“Despite the big medical advantage, there is a concern about potential radiation risks.”
The contents they concluded are as follows.
“The rapid increase in the use of CT scan in the United States has raised concerns about potential cancer risks. This is because even small risks can be interpreted as many future cancer when many people are exposed. Our estimate is that about 29,000 future cancers can be related to the use of CT scan in the United States in 2007.”
Sue quickly until April 2025:
Research has been published Zaemagi (April 14, 2025) We anticipated the number of future cancers due to radiation exposure due to computed tomography (CT) test. The researchers used the data from the University of San Francisco, the University of California, and modeled the influence of radiation.
They were estimated roughly 103,000 cancer It is highly likely to be caused by 93 million scans of 60 million people in 2023. The risk is the highest in children and adolescents, but more adults receive CT scans.
Scientists conclude:
“CT can often save life, but potential damage is often overlooked, and even very small cancer risks will lead to a large number of future cancers given the use of a huge amount of CT in the United States.”
“In this study, about 5%of the annual cancer diagnosis or 100,000 cancers were expected to be caused by the use of CT in 2023. Despite the public interest in potential side effects, CT use has increased significantly in the United States since 2009. In 2023, 93 million CT tests were carried out in the United States. It is the creed of CT video and must be applied to compromise to alleviate potential damage. ”
The main author of this study told THE San Francisco Chronicle (April 14, 2025):
“The goal is not to surprise the patient, but whenever you need to think about every time you suggest CT? Why do you understand why they need and work with your doctor?
Dr. Rebecca Smith-Bindman is a professor of radiation and mechanics at the University of San Francisco.
As the first author of research She points out:
“CT can save life, but potential damage is often overlooked.
“Given the use of many CTs in the United States, many cancers can occur in the future if the current practice does not change.
“Our estimates are assumed to be equivalent to other important risk factors, such as alcohol consumption and excessive weight.” “Reduce the number of scans and reduce the dose per scan to save life.”
“There is an unacceptable change in the dose used in the current CT, and some patients receive excessive doses.”
How many radiation is involved in the CT scan?
When we first wrote about this problem about 16 years ago, we wrote:
“Radiation exposure from computed tomography has been diverse up to 13 times in background radiation of less than a year. Some experts compared the radiation of a single CT scan at 400 chest X-ray.The other experts compared them in 400 thoracic X-Ray.The other experts were the survivors of Nagasaki atoms of the Nagasaki atoms. As a result, the patient must absolutely agree.
Today, it is much more complicated. This is because there are various computer tomography scanners in the market. There is a heart scanner used to look at the heart. They can identify clogs and prepare for an arbitration of arterial arteries or plans to replace the valve.
The head CT imaging machine helps to diagnose brain tumors or stroke. Chest CT scanners can help you identify waste species or lung cancer.
Different types of machines use different radiation. Now there are low -capacity scanners and ultra -ultra -capacity CT scanners. It is a bit difficult to try and try quantitative numbers behind each machine.
Estimated Low capacity CT scanning machine:
“… It is safer for everyday testing by releasing 10 -fifth of the radiation of regular CT scan.”
Such low -dose equipment is especially useful when selecting the waste problem or checking the problem of the pediatric population.
that North American Radiation Society We suggest a time when ultra -low dose CT is appropriate.
“Denoised Ultra-Low Dose CT (ULDCT) can effectively diagnose pneumonia in patients with immunity by using only 2% of the radiation capacity of the standard CT. Radiation: Heart Chest Video (March 13, 2025). ”
Questions to ask questions before Agree to CT scan:
Assuming it’s not in an emergency, there are some questions you want to ask about the benefits and risks of CT video.
- Why are you ordering a current CT scan?
- How important is this image to analyze or diagnose my health problems?
- Is low -capacity CT scanning devices or ultra -high dose image equipment suitable for my situation? If so, can you ask for such a scan where this kind of equipment is located?
- Does my insurance pay low -capacity scan?
- Does the result of the CT image change my treatment plan?
- Delaying a scan adversely affects your health.
Of course, in an emergency, CT scan can be important and you need to ignore all such questions.
Final word:
I have received great benefits from CT scan when I was suffering from intelligence due to INTUSSUSCEPTION. It made the surgeon a quick diagnosis and in a timely manner to start the procedure.
How are you? Have you ever scanned CT? How was that procedure? Did you reveal something important? Or is it “if” initiative? Share your experience in the opinion section below. If you think it’s worth this article, share it with your friends and your family. You do not know when someone needs the questions that we need above. Ask a doctor who recommends scanning.
