What Is Attenuation In Radiology?

Attenuation Units. In radiology, attenuation is measured in Hounsfield Units (HU). The HU scale assigns values to different tissues, with air assigned a value of -1000 HU, water at 0 HU, and bone at around +1000 HU. This scale helps radiologists interpret images by quantifying the degree of attenuation. Attenuation in CT Scans
