What is the primary role of X-rays in medical diagnostics?

The primary role of X-rays in medical diagnostics is to visualize the internal structure of the body. X-ray imaging works by passing a controlled amount of radiation through the body, which then creates images based on the varying densities of tissues and structures within. Dense materials, such as bones, appear white on the X-ray film or digital image, while softer tissues allow more radiation to pass through, resulting in darker areas.

This capability makes X-rays invaluable for diagnosing conditions such as fractures, infections, and tumors, as they provide clear images of the skeletal system and certain soft tissues. Understanding the internal anatomy through X-rays allows healthcare professionals to make informed decisions about treatment and care planning. Other options, such as treating diseases or monitoring vital signs, pertain to different branches of medical practice and do not align with the primary function of X-ray imaging.
