It is also important for treatments that achieve the cure of lethal diseases; all of these being able to save so many lives or prevent a condition that could harm the person.

5 Risks of Different Radiology Technologies - Home

Out of risks

Radiation exams are out of risk, although the person is exposed to radiosondes during the analysis, the amount of radiation to which they are exposed is minimal and totally reliable.

In addition to providing much more detailed information on the atomic structure of the person being analyzed, compared to other methods such as exploration surgery.

X-rays are used to scan your body and find out if you have health issues that cannot be spotted by the naked eye. Despite the great benefits of X-rays, they do emit radiation and pose a risk of causing cancer. Below I’ve looked at how safe the three main types of X-ray are.

Are X-rays radioactive?

To get things out of the way, X-rays are not radioactive. X-rays are a type of electromagnetic radiation that occurs naturally and X-ray machines do not contain any radioactive material, meaning that even when they are energized there is no risk of you being contaminated.

Will X-rays give me cancer?

Because X-rays are a form of radiation, they classified as a carcinogen and this means that they are capable of causing cancer in living tissue. However, the risk of you getting cancer from an X-ray is small, with there being around a 1.2% chance of an X-ray causing cancer.

Which X-ray proceedure is most likely to cause cancer?

The cancer risk posed by X-rays depends on the part of your body being examined, with some areas receiving a higher concentration of radiation than others. Below are the different major body areas and how much natural background radiation (NBR) an X-ray on them is equivalent to:

  • Chest: 2.4 days of NBR
  • Skull: 12 days of NBR
  • Lumbar spine: 182 days of NBR
  • Head: 243 days of NBR
  • Upper gastrointestinal: 2 years of NBR
  • Barium enema: 2.7 years of NBR
  • Abdomen: 2.7 years of NBR

How safe is radiography?

Radiography is the most common type of X-ray that you can have, along with being the safest. Radiography is a type of imaging that lets physicians see the internal form of a life-form or object, giving the classic X-ray image. To create an image, electromagnetic radiation is projected towards an object.

What are the risks of fluoroscopy?

While radiography produces an internal image of an object, fluoroscopy is more like a movie of your insides. Fluoroscopy creates a continual image, making it possible for a radiographer or radiologist to see how your body’s organs are working. Though fluoroscopy does involve more radiation than radiography the amount is still minuscule.

Is computed tomography safe?

If you’ve ever seen a film or TV show where a patient is sent into a scanner, then they will be having an X-ray by computed tomography (CT). CT produces a 3-D image of your internal structure by sending a number of slice style rays over your body. Due to the large number of scans made during a single sitting, CT scans emit the most radiation of all X-rays but are still safe – hence why they are used.

While X-rays are a natural form of radiation and a type of carcinogenic, they are very safe and the benefits of having one vastly outweigh the risks of getting cancer. So next time you’re booked in for an X-ray, remember that the chances of your life being saved by one are much higher than the threat of getting cancer.

Nuclear medicine is a specialty where various radioactive materials are used, which through their gamma rays will emit the internal images of the body, especially the place you’re examining exactly.

It’s an alternative way to be able to visualize more deeply how the patient is and thus give a more accurate diagnosis. Here we leave you some facts about nuclear medicine you must know:

Normally this type of exam is applied to detect diseases or conditions such as respiratory problems, blood flow problems, bone evaluation and any fracture, tumor or infection that has been suffered; abnormalities in the brain, neurological disorders, cancer, and many other things.

The way nuclear medicine has benefited the world is incredible because through it millions of lives have been saved by detecting diseases on time or by applying radiation treatments. We hope it will continue to advance and we can find more advantages in nuclear medicine.

Radiology is one of the most sought after areas of medicine because it has become indispensable for the detection of many diseases, disorders and more with the passage of time. Maybe not surprisingly it really is a very difficult area, where the technologies are increasingly more complex and have more demands for those choosing this path.

You Must Be Physically Prepared

Study groups are a great way to study, because not only can you share what you know about many important subjects with other people and be able to learn from them in return, by doing it this way you’ll likely feel more motivated to study than doing it alone in your home or in the library.

Even with the importance of Radiology to medicine right now, according to some studies it’s expected by the beginning of 2020 that the area of Radiology will grow by more than 20% on a global scale due to the increasing demand that’ll make it more necessary than ever in the medical field.

Some people have entered these rooms, but surely many didn’t know of some things to do before entering. So here you have some things you should do before going into the x-ray room:

Consult With Your Doctor First

It’s advisable to arrive in advance for the exam appointment because usually you have to fill out some documents by hospital rules, and to know more about your medical history. And obviously, you must have the doctor’s order, which is where the technologist will be informed about the parts that will be examined.

X-rays mean that your body, or especially the part that’s being examined, is exposed to small doses of ionizing radiation, and all of this, to be able to have an internal image. If you need to make one, you just have to take into account these tips and you’ll be ready.

Radiology is one of the medical specialties that exist, where physical studies are carried out inside the body and these generate the images to give some diagnosis, treatment or prognosis.

It’s said radiation can cause some risks, especially if you already have certain conditions or diseases. For example, women who are pregnant and exposed to high radiation can have as a consequence a child with some kind of alteration in their development, genetic mutation or intellectual disability. It isn’t so common, but it has happened with extreme cases.

Many people don’t know the danger to which they are exposed, that’s why here we leave you some risks of different radiology technologies:

Here’s what’s known, a nuclear magnetic resonance will generate waves where internal images of the body that’s being analyzed can be obtained. This really becomes dangerous if exposed to something that has metal, for example, a pacemaker.


xrays - 5 Risks of Different Radiology Technologies

This is a treatment where it is used ionizing radiation; instead of x-rays, positively charged protons are used. It’s very common in treatments such as cancer. Some direct lesions that have been seen in very serious cases of exposure to radiation, such as hair loss, skin lesions or cataracts.

Nuclear Medicine

In nuclear medicine, radiotracers or radiopharmaceuticals are used by various routes through the body of the person, for the diagnosis and treatment of any disease. This can generate some allergic reaction in some people, but it isn’t so common.

CT Scans

mri magnetic resonance imaging2 - 5 Risks of Different Radiology Technologies

With the tomographies, people are exposed to X-rays in a part of the body that’s displayed on a computer so can detect the internal part. Here you’re exposing yourself to radiation, but the risk will depend on how many constant radiations you’re exposing yourself in some period of time.

It’s not that risky, because it’s really exposed to small amounts of radiation as long as they aren’t so followed and obviously depending on the part of your body where you’re examining and which of these forms is being examined.
