Computed tomography, based on X-rays, is used to image various parts of the body. It is a popular technique used to study bone lesions, especially in delicate and small areas, such as the ears and sinuses. With this method, we can obtain images with high accuracy. Additional 3D reconstruction is often used for bone and joint examinations. 3D images in color provide more information, which facilitates accurate diagnosis and treatment planning.
