Radiologist Eduard Keller told about radiological research in the news radio show “Health Time”.
The most commonly used radiological examination, which almost everyone has to perform during their lifetime, is an X-ray. Although X-rays were discovered more than 100 years ago, this study is still considered a true classic.
“It simply came to our notice then. This is not a “written off” study. However, X-rays are harmful, unlike any kind of ultrasound-free ultrasound or magnetic resonance imaging. It is therefore necessary to choose who needs that investigation and it cannot be abused. This research has not lost its relevance yet, “said E. Keller.
According to the doctor, there is currently no better way to examine the lungs without an X-ray. Another possible option could be unless computed tomography, but it also uses the same X – rays, only 1000 times more.

“A simple x-ray when the question of whether a bone is broken or a healthy lung is a very good, quick test. Clearly, the x-ray was slightly pushed to the side by computed tomography, magnetic resonance imaging. However, it remained as an emergency examination, “the doctor said.
Echoscopy and MRI are considered harmless
Another commonly used study is ultrasound – This examination is often referred to by people as an ultrasound examination.
“It’s a very good study if you have a good machine and a good researcher because you need skills. A good researcher can use an ultrasound to examine small structures, even blood vessels, ”said E. Keller.
The doctor recalled how this study had changed in the 20 years since he began working. Now the interlocutor with a smile remembers a time when the machines were much worse than they are today.
Ultrasound examination

“About 20 years ago, when I started working, there was an old machine in the polyclinic, then there was complete despair. A man came with a cyst in the groin, she obviously felt it. I put on the sensor and it showed only a centimeter from the surface of the skin, nothing was possible to see. Such despair was that of horror.
Current devices are not even comparable. It’s the same as sitting in a 30-year-old car and the current one, “said a news radio interviewer.
X-rays were initially considered innocent, but it is now known that such tests cannot be abused. At that time, ultrasound examinations in terms of human exposure are among the innocent. There are essentially no limitations to this study.
And magnetic resonance imaging is not recommended during the first 3 months of pregnancy, even with an older pacemaker, although in general, this test is not thought to be harmful to humans.
“Magnetic resonance imaging is thought to be a harmless study. It has been used in Lithuania for about 20 years. The tissues that have the most water are best seen with this study. These are the lungs, the intestines, the bones will not be examined much. It is best suited for the brain, spine, joints, liver, pancreas, prostate, uterus. Even the heart can be examined by magnetic resonance, “said the interlocutor.

The doctor also recalled the curious situation that occurred when the patient was examined by magnetic resonance imaging.
“It simply came to our notice then. The technician said the patient would lower his leg, but he did not lower it. He repeated it several more times. Later, already angry and the door opened, he repeated the same thing. The man then said that he could not lower his leg because metal was placed in the thigh, and the magnet pulled the leg up with the metal, which prevented him from stretching it, “E. Keller recalled.
One of the more common fears of patients is that the magnet will “peel off” during a magnetic resonance imaging test. However, the doctor reassures that this is basically impossible, but older dentures can start to heat up as well as pull. However, the prostheses now in production have been non-magnetic for decades, so this study is safe.
The most harmful are X-ray and computed tomography examinations
According to the doctor, the most important of all radiological examinations should be considered before performing X-rays and computed tomography, as their frequent performance can have negative consequences.
The doctor also notes that computed tomography is the most commonly abused.
“It’s magnetic resonance on the wave, but it’s not harmful, so there’s nothing very bad. At that time, computed tomography has a lot of harmful rays, so this test is done more often than necessary and sent more often than necessary.
However, this is a trend not only in our country, but all over the world. Everyone wants to protect themselves, because if you release a person without diagnosing the disease, he will take you to court. As a result, it is better to give him rays. I think it would be possible to halve the number of these studies, “said Keller.
