A CT (Computed Tomography) scan is an imaging procedure that uses special X-ray equipment to create detailed pictures inside the body. The images created by a CT scan show more detail and can often diagnose medical conditions earlier and more accurately.
Doctors use this information to examine organs, bones, soft tissue, and blood vessels. To diagnose illnesses or injuries much quicker and improve treatment options available for patients.
During the Scan
- Patients typically lie on a table that slides into a large doughnut-shaped machine.
- They will ask them to remain still while they take scans from different angles of internal organs and structures once they have settled.
- Stay as relaxed as possible – any movement or breathing too quickly can make scans blurry or distort results.
- The entire process usually lasts between 15 minutes and an hour depending upon what’s being examined.
- In addition, most clinics use a contrast dye to highlight areas that need further focus which makes patients feel discomfort.
- Radiation: (Also called a useful beam) is the radiation emitted directly from the X-ray tube that is used for patient imaging.
- Primary Barrier: It is a wall, ceiling, floor, or other structure that will intercept radiation emitted directly from the X-ray tube.
- Secondary Radiation: Consists of X-rays scattered from the patient and other objects such as imaging hardware and leakage radiation from the protective housing of the X-ray tube.
- Barrier (Secondary): It is a wall, ceiling, floor, or other structure that will intercept and attenuate leakage and scattered radiation.
Radiation Exposure
CT scans are an important diagnostic tool, used to diagnose a wide range of medical conditions. However, the benefits from such imaging can be great, there is also the potential risk associated with radiation exposure.
These exposures can add up with repeated scans or multiple different types of images acquired at once. During a standard scan, there is up to 100 times more exposure than X-rays. Also, high doses can significantly increase their risk of developing certain types of cancers later in life.
When calculating the total dose for children or pregnant women, doctors must take into account not only this radiation exposure from one single exam but also any other prior irradiations encountered in their life as well.
We are regularly exposed to various kinds of radiation like radioactive materials, radon a radioactive gas. It comes from the natural breakdown of the uranium in soil, water, rocks, building blocks, and cosmic rays from outer space.
Countries vary in their background radiation. The largest source of background radiation is radon which is typically about 2 mSv per year, a natural gas found in our homes.
Location is also important, being at a higher altitude increases a person’s exposure. Radiation we get from the CT scan machines, and X-rays are ionizing radiation.
These forms of radiation can travel through living tissue and interact with molecules to form ions. After that causes damage in cells within that area, leading to potential health risks.
Ionizing radiation can damage the cells and the tissues, and sometimes they just do the job in the wrong way. They leave the small areas neglected which results in DNA mutation which later on in future develops the cancer cell.
The average radiation one should take is 3 millisieverts per year(mSv).
The extent of potential damage depends on several factors:
- type of radiation
- sensitivity of the affected tissues and organ
- manner and length of time exposed
- radioactive isotopes involved
- characteristics of the exposed person (age, gender, weight, etc)
Methods such as radiographs or X-rays involve very low doses while other techniques like CT scans or PET scans may require higher levels of exposure.
The amount of the measure of radiation exposure depends on the imaging test and the part of the body, the absorption rate will also vary depending on an individual’s age and weight.
- A single chest X-Ray exposes the patient to about 0.1mSv. People naturally expose themselves to the same amount of radiation over about 10 days.
- Mammogram exposes a woman to about 0.4 mSv; which is equal to about 7 weeks of natural exposure.
- Lower GI (Gastrointestinal) series using x-rays of the large intestine exposes a person to about 8 mSv, or equal to the amount expected over about 3 years.
- CT scan of the abdomen (belly) and pelvis exposes a person to about 10 mSv.
- PET/CT exposes a person to about 25 mSv of radiation. This is equal to about 8 years of average background radiation exposure.
Radiation exposure can also cause acute effects such as nausea and vomiting, skin redness, hair loss, radiation burns, acute radiation syndrome, or even death.
Excessive Radiation Exposure can increase the risk of cancer, during nuclear emergencies, it releases radioactive iodine, which if swallowed or breathed can develop thyroid cancer.
Ensure Radiation Safety for patients
- Limiting the total “beam–on” time
- Avoiding oblique lateral projections
- Collimation to limited beam size
- Selecting low dose rate protocol
- Use of exposure protocols for patient examinations including pediatric patients
- The use of DLP(Dose Lenght Product)in CT and DAP(Dose Area Product) values for IR (Interventional Radiology)procedures
- record-keeping patient’s doses for CT and IR procedures.
Does extra radiation increase a person’s cancer risk?
Radiation Exposure depends on various factors like age, health, height, weight, gender, and other factors. While research has yet to provide concrete answers, many studies have linked exposure to high levels of radiation with an increased possibility of health problems.
Those who voluntarily receive high-dose radiotherapy treatments can be at higher risks for short or long-term health effects related to cancer development. While it may not always lead directly to cancer formation.
Healthcare professionals should monitor exposure to large amounts of extra radiation with frequent checkups.
There is a growing concern that extra radiation such as MRI and CT scans might increase the risk of cancer in kids. Studies have found an increased risk of central nervous system tumors. It is especially for children who have several medical imaging tests within close succession.
However, doctors can minimize this potential risk by discussing other diagnostic modalities which do not involve radiation. In addition to monitoring usage for symptoms alone, it’s important to consider any additional risks associated with repeated exposure.
It’s important to consider this information when using any form of medical imaging. Healthcare professionals should supervise overexposure carefully to avoid potentially serious consequences later on in life.
Proper safety protocols must be followed to minimize the radiation impact of CT scan machines. Exposure to radiation increases a person’s risk of developing cancer or other illnesses and has an exponential effect.
It is important for healthcare workers to understand the implications of ionizing radiation so that they can take steps to mitigate its dangers and operate these machines safely. By doing this, we can ensure that all patients get access to timely treatments without compromising their health in any way.
Understanding the impact of Radiation Exposure from a new generation CT Scan Machine.
