X-Ray vs. CT Scan: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 26, 2023
An x-ray is a single image capturing the internal structure using radiation, while a ct scan produces detailed, cross-sectional images from multiple x-ray angles.
Key Differences
An x-ray is a diagnostic tool that utilizes a controlled amount of radiation to visualize the internal structures of the body, including bones, some organs, and tissues. It generates a two-dimensional image. On the contrary, a ct scan, short for computed tomography scan, uses x-ray equipment to obtain images from different angles, processing them with computer technology to produce cross-sectional slices of the body.

X-rays are typically used for examining the skeletal system, detecting fractures, infections, and tumors. They are quicker and generally more accessible. In contrast, ct scans are often used to examine complex parts of the body, like the brain, lungs, and abdominal organs, offering more detailed information.

With x-rays, the patient is exposed to a minimal amount of radiation. The process is simple and fast. In a ct scan, however, the patient is exposed to a higher radiation dose, as multiple images are captured from various angles to create detailed slices of the area of interest.

While x-rays provide a broad overview of an area, they might not capture the nuances of soft tissues or the depth of structures. Ct scans, being more detailed, can offer three-dimensional reconstructions, proving invaluable in diagnosing internal injuries, tumors, and blood clots.

In essence, while both x-rays and ct scans use radiation to capture internal images, their purposes, processes, and details differ significantly, with ct scans offering more comprehensive insights into the body's interior.
