Question

Quizplus · Accepted Answer

CT (computed tomography) measures the attenuation values of x-rays with the Hounsfield unit. The Hounsfield unit is a scale that is based on the attenuation values of soft tissue, bone, and air. It allows for the creation of detailed cross-sectional images of the body. Radionuclide scintigraphy and bone scans use different imaging techniques and do not measure attenuation values with the Hounsfield unit. X-rays also do not use the Hounsfield unit scale.
