Many people feel anxious when their doctor recommends radiological examinations, such as X-rays, CT scans, or other procedures that use radiation. This concern is understandable, as many myths surrounding medical radiation persist. However, when performed properly, medical radiation is safe and highly beneficial in supporting diagnosis and treatment.
Types of Radiology Examination
There are several types of radiological examinations that are commonly used, both to detect disease and to support medical procedures, including:
- X-ray photo
- Ultrasonography (USG)
- Fluoroscopy
- Computed Tomography/Computerized Axial Tomography (CT/CAT Scan)
- Positron Emission Tomography (PET Scan)
- Magnetic Resonance Imaging (MRI)
4 Myths and Facts About Medical Radiation You Need to Understand
Myth 1: Medical radiation is always dangerous
Fact: Radiation does have risks, but the amounts used in medical examinations are very small and strictly controlled according to international standards. The benefits far outweigh the risks.
Myth 2: One X-ray can cause cancer
Fact: The radiation dose from a single X-ray is very low, even less than the natural radiation exposure we receive daily from the environment. The risk of cancer from a single X-ray is virtually non-existent.
Myth 3: Radiology examinations are not acceptable for children
Fact: Radiological examinations may be performed on children with clear medical indications. Doctors will adjust the radiation dose to as low as reasonably achievable (the ALARA principle).
Myth 4: CT scans are more dangerous than MRIs
Fact: CT scans do use X-ray radiation, while MRIs do not. However, CT scans are very useful in emergency situations because they provide quick results. Both are safe when performed as directed by a doctor.
Why Not Be Afraid?
- All radiology procedures are performed under the supervision of a radiology specialist.
- The tools used comply with international safety standards.
- The radiation dose is adjusted to be as low as possible without reducing image quality.
- The risks are far less than the benefits in helping diagnose disease.
When is a Radiology Examination Needed?
Radiology plays a vital role in various medical fields. This examination is typically performed upon referral from another doctor who requires more detailed imaging to confirm a diagnosis or determine treatment options. Radiology results allow doctors to gain a clearer understanding of a patient's condition.
Some conditions that generally require radiological examination include:
- Fracture,
- Tear in the muscle,
- Suspected cancer or tumor,
- Pregnancy,
- Blockage in the arteries or blood vessels,
- The presence of foreign objects in the body,
- Trauma due to accident,
- And infection.
Radiology examinations are a crucial step in helping doctors obtain a more accurate picture of your health. Clear results allow for a more precise and expedited diagnosis and treatment. Therefore, if your doctor recommends radiology, don't hesitate to undergo it to ensure your health remains intact.
