Here are the types of chest X-rays and their primary areas of use:

* PA Chest X-ray (Posterior-Anterior): An imaging method where X-rays enter from the patient's back and exit from the front, frequently used for routine evaluation of the lungs and heart.
* AP Chest X-ray (Anterior-Posterior): An imaging technique where X-rays enter from the patient's front and exit from the back, generally preferred for bedridden or critically ill patients.
* Telecardiography (Telegrafi): A special type of chest X-ray performed for a more detailed examination of heart and great vessel structures and a more accurate assessment of their dimensions.
* Decubitus X-ray: An imaging technique used to detect fluid accumulation or the presence of free air in the pleural space, with the patient lying on their side.
* Apicolordotic X-ray: A special projection used to visualize the upper (apical) parts of the lungs more clearly by minimizing the superposition of the clavicles and ribs.
* Fluoroscopy: A dynamic imaging method used to evaluate the movements of the lungs, diaphragm, and other intrathoracic structures in real-time (dynamically) and to examine pathologies.
