Röntgensirontatutkimus

Röntgensirontatutkimus, also known as plain radiography or X-ray, is a widely used medical imaging technique that utilizes ionizing radiation to create images of the internal structures of the body. This non-invasive procedure involves passing a small dose of X-rays through the body onto a detector, which captures the resulting pattern of absorption. Dense tissues, such as bone, absorb more X-rays and appear white on the image, while less dense tissues like soft tissues appear in shades of gray, and air appears black.

The primary applications of röntgensirontatutkimus include the diagnosis of fractures and dislocations, detection of lung diseases like pneumonia and tuberculosis, identification of foreign bodies, and evaluation of abdominal conditions. It is often the first imaging modality used in many diagnostic pathways due to its accessibility, speed, and relatively low cost. The examination is typically performed by a radiographer, and the resulting images are interpreted by a radiologist who provides a diagnostic report. While generally safe, the radiation exposure necessitates careful consideration, especially for pregnant women and children.
