Radiografii

Radiografii, also known as X-rays, are a non-invasive medical imaging technique that uses electromagnetic radiation to create images of the inside of the body. This technology relies on the principle that different tissues absorb X-rays to varying degrees. Dense tissues like bone absorb more X-rays, appearing white on the image, while softer tissues like air or fat absorb less, appearing in shades of gray and black.

The process involves an X-ray tube emitting a beam of X-rays that passes through the patient's body. A detector, typically a digital sensor or film, is placed on the opposite side to capture the X-rays that have been transmitted. The resulting image is a two-dimensional representation of the internal structures. Radiografii are commonly used to diagnose fractures, detect pneumonia, identify foreign objects, and screen for certain types of cancer, such as mammography for breast cancer.

While generally safe, X-rays involve exposure to ionizing radiation. Medical professionals adhere to strict protocols to minimize radiation dose to patients, using the lowest effective exposure and shielding sensitive areas when possible. The benefits of diagnostic information gained from radiografii typically far outweigh the minimal risks associated with radiation exposure. Interpretation of radiografii is performed by trained radiologists who analyze the images to identify abnormalities.
