Radiology is a branch of medicine to know the inside of the human body using imaging technology, both electromagnetic waves and mechanical waves. Doctors who specialize in radiology are referred to as radiologists or radiologists.
Radiologists themselves act as expert consultants who are tasked with recommending the required examinations, interpreting medical images from the results of examinations, and using test results to direct the treatment according to the patient's condition. One of the most well-known types of radiological examinations is X-rays using X-rays. Even so, radiological examination is not only that.

Radiological examination is an important procedure for diagnosing disease
In the medical world, radiology plays a very important role. Without imaging technology, the disease will be difficult to diagnose and the existing treatment will not work optimally. As a result, more and more people are sick and die because the disease is not diagnosed early.
The key is simple, the earlier the disease is diagnosed, the greater the chance for patients to experience recovery.
Some conditions that can be known through radiological examination are:
Division of the radiology field
Radiology can be divided into two different fields, namely:
1. Diagnostic radiology
Radiological diagnosis helps doctors and health staff to see the structure in your body using imaging technology. This was done for:
- Knowing the condition of the inside of the patient's body
- Diagnosing the causes of symptoms the patient complained
- Monitoring how well the patient's body responded to treatment
- Screening for various diseases, such as cancer, heart disease, lung disease, stroke, joint and bone disorders, epilepsy, strokes, infections, disorders of the thyroid gland, and so on.
The most common types of diagnostic radiological examinations include:
- Computed tomography also known as computerized axial tomography (CT / CAT) scans, including CT angiography
- Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA)
- Nuclear examinations, such as bone scan thyroid scan, ] and thallium heart stress test
- X-ray photo
- Positron emission tomography also called PET imaging, PET scan, or PET-CT when combined with CT
- Ultrasound (USG)
2. Radiology intervention
When to go to a radiologist?
Before someone is advised to consult radiologist, there are several stages of examination that must be undertaken. In the initial stage, a patient will first undergo an examination at a general practitioner. If at this stage the general practitioner finds some symptoms that lead to certain diseases that require further examination, the general practitioner will refer the patient to the radiologist. The same thing can happen if you go to a specialist doctor.
Later, the radiologist will conduct further examinations to establish the initial diagnosis made by general practitioners or specialists. To ensure a diagnosis, the radiologist will usually do the most appropriate examination to diagnose your complaint.
The results of examinations conducted by radiologists can provide additional information to general practitioners or specialists who provide referrals to radiology doctors.
Examination side effects with imaging technology
Although checks carried out with imaging technology are fairly safe, still there are several risks of possible side effects. Some of these include:
- Patients can experience nausea, vomiting, dizziness, itching on the skin, feeling a metallic sensation in the mouth due to contrast fluid injected into the body. In rare cases, contrast fluids can also cause blood pressure to experience a drastic decline, anaphylatic shock, and a heart attack.
- X-rays can affect the development and growth of infants and fetuses.
- There is a study that states that CT scan procedures can increase the risk of cancer and can damage DNA, especially in pediatric patients. However, this risk is very small to occur, possibly only 1 in 2,000 cases. So, CT scans are still considered a safe enough examination and can help doctors evaluate the condition of their patients.
- Contrast fluids can cause allergies in some people.
Technical preparation before radiology examination
Basically each procedure requires different preparation. Before undergoing a radiological examination, the doctor will usually tell what the patient must prepare. The following are some of the common things that are most often recommended by doctors:
- Wear comfortable and loose clothing to make it easy to open when the examination takes place. Even so, some hospitals will provide special clothes for patients to wear.
- Removing jewelry, watches, glasses, or metal-containing instruments on the body. If you have metallic implants in the body, such as the installation of a heart ring, or a nut in the bone, immediately report it to the doctor. Because, these objects will block X-rays to penetrate into the body.
- Patients may be asked by doctors not to eat and drink for several hours before the examination is done.
