Hyperdense materials can be useful for identifying abnormalities or structures of interest in imaging studies.
What is hyper attenuation on a ct scan?
Strictly speaking, the physics of CT scanning involves attenuation of the x-ray by tissues in a manner not always exactly congruent with density differences. Hyperattenuation is a better term than hyperdense for more white and bright on the image. Hyperdense: More dense than brain. Hyperdense on CT shows more white and bright, like bone. Hyperdense abnormalities may be blood if acute, calcium, metal artifact, some tumours
