Understanding X-ray Limitations: Penetration, Distortion & Radiation

Limited penetration: X-rays can only penetrate certain materials. They are readily absorbed by dense materials, such as bone and metal. This means x-rays cannot, for example, image structures deep within the body or see through dense objects.

Image distortion: X-rays can distort images due to magnification and scattering. This is particularly problematic in soft tissues where there isn’t much detail to begin with.

Ionizing radiation: X-rays utilize ionizing radiation. This means they have enough energy to knock electrons off of atoms, which can damage DNA and cause several health problems including cancer. As a result, x-ray imaging is kept to a minimum.

Lack of color and detail: X-rays images provide limited information when it comes to subtle tissue differences and can overlook structures that are the same density as the surrounding tissues.
