X-rays (X-ray studies)

X-ray explained in plain language: preparation, what to expect, safety considerations, and how clinicians use the results.

X-ray is a topic hub designed for quick orientation and deeper reading when needed.

Find practical steps, common questions, and links to detailed articles that explain causes, testing, and evidence-informed options.

What you can explore:

Indications: why the test is ordered and what it can show
Preparation steps and what to expect during the procedure
Safety and risks, including when alternatives may be preferred
How results are reported and how they guide next steps

Procedures are most useful when matched to symptoms and clinical questions.

If there are severe symptoms or red flags, do not delay urgent evaluation.

Bronchography

Bronchography allows doctors to assess the condition of the bronchi, identify possible changes such as tumors, structural abnormalities or obstructions, and helps in establishing diagnoses and planning treatment.

Excretory urography

Excretory urography (or intravenous urography, IVU) is a medical procedure used to visualize the urinary tract using x-rays.

Cystography

Barium X-ray: preparation, what it shows

X-ray examination is based on the fact that human tissues of different densities absorb the rays emitted by the X-ray tube differently.

Darkening on X-rays in adults and children

Quite often as part of diagnostic measures, the doctor prescribes a patient radiography. This procedure is performed to detect pathologies, damage to tissues and organs, as well as to clarify the results of other studies.

X-ray of the thoracic spine in two positions

Radiation exposure in X-rays

X-rays are a stream of electromagnetic oscillations with a length that falls within the range between ultraviolet and γ-rays. This wave variety has a specific effect on the human body.

X-ray of the sternum in 2 projections

Typically, a chest X-ray is performed for diagnostic purposes, but targeted visualization of the flat breastbone in the middle of its anterior wall - a sternal X-ray - may be required.
