X-ray

What is an X-ray (RTG)?

RTG is short for “Radiography,” a diagnostic imaging technique that uses X-rays (radiation) to obtain images of internal body structures. It is one of the most commonly used diagnostic techniques in medicine, allowing the detection of abnormalities in organs and bones, including fractures, cancerous changes, respiratory diseases, and abdominal issues.

Imaging tests include computed tomography (CT), commonly known as "scans," magnetic resonance imaging (MRI), and mammography.

Types of X-ray exams

The most commonly performed X-ray exams include:

• chest X-ray,
• abdominal X-ray,
• spinal X-ray,
• foot X-ray,
• knee X-ray,
• hand X-ray,
• elbow joint X-ray,
• cephalometric X-ray,
• panoramic dental X-ray,
• rib X-ray,
• dental X-ray,
• sinus X-ray,
• ankle joint X-ray,
• shoulder joint X-ray,
• hip joint X-ray.

Indications for X-ray

An X-ray may be ordered in cases of:

• headache, back pain, or limb pain that persists despite painkillers;
• suspected bone fracture;
• joint sprain;
• dislocation;
• swelling, bruising, or visible deformities on the body;
• difficulty moving;
• pain and stiffness around the injured area.

The X-ray procedure

If there are any concerns or questions about the procedure, the patient should consult the medical facility where the X-ray will take place. The medical staff will provide all necessary information to alleviate the patient's concerns.

FAQ

What does an X-ray exam look like?

The X-ray exam is performed by a radiologist and involves several steps necessary to obtain a precise image. The first step is preparing the patient by exposing the examined area, removing jewelry, and wearing a special protective apron. The patient is then positioned appropriately next to the X-ray machine.

The exam is conducted by a technician responsible for obtaining the correct image and positioning the patient properly. During the procedure, the patient must remain still to avoid a blurry image. After the X-ray, the radiologist interprets the image.

How to prepare for an X-ray?

An X-ray does not require special preparation. It is necessary to have a current referral from a doctor and inform the radiologist about any prior surgeries and pregnancy.

Make sure you are not wearing any metal objects, such as jewelry or clothing fasteners. It is also advisable to wear appropriate clothing that allows easy exposure of the area to be X-rayed, ensuring comfort during the examination.

Is an X-ray exam painful?

The X-ray exam is completely painless. Patients may experience discomfort while positioning the body in the area where pain is present.

How long does an X-ray exam take?

Standard X-ray exams typically take a few minutes. If additional positions or images are needed, the exam time may be extended.

For contrast-enhanced exams, the duration may also be slightly longer.

What are the contraindications for an X-ray?

There are several contraindications for an X-ray. The primary one is pregnancy, as the radiation can negatively affect a developing fetus. People with iodine or contrast allergies used in X-ray imaging should also avoid this type of examination.

What is the difference between an X-ray and an ultrasound?

X-rays and ultrasounds are two different diagnostic imaging methods. X-rays use radiation to create images of internal body structures, while ultrasounds use sound waves.

X-rays are more useful for diagnosing fractures, bone deformities, or internal organ problems. Ultrasound is more commonly used to examine soft tissues, pelvic organs, or during pregnancy to monitor fetal development.

Both methods have their applications and limitations. The choice of the exam depends solely on the attending physician and the patient’s health condition.

What is the difference between an X-ray and an MRI?

X-rays and magnetic resonance imaging (MRI) are two different medical imaging techniques. MRI uses a strong magnetic field and radio waves to obtain images of internal tissues and organs. This method is more precise and non-invasive.
