What is the difference between ct and xray?
A doctor has provided 1 answer
Contrast: An xray (also called radiograph) is done by sending xrays through a body part but only in one projection so there is overlap of body parts and contrast is not very good. Ct also uses xrays but the final cross-sectional image (slice) is reconstructed from a combination of xrays shot from multiple directions/projections; therefore, there is no overlap of body parts and much better contrast.
