What is the Hounsfield Unit (HU) range for dense bone?

The Hounsfield Unit (HU) scale measures radiodensity in CT imaging, where the scale is based on the attenuation of X-rays through various substances relative to water. Water is assigned a value of 0 HU, while air is typically -1000 HU.

Dense bone, due to its high mineral content and density, exhibits a significantly high attenuation of X-rays. Therefore, it generally falls in the range of +1500 to +2000 HU. This level of radiodensity is essential in clinical practice as it helps distinguish bone structures from other tissues in CT images, contributing to accurate diagnoses and treatment plans.

The other ranges provided do not accurately represent the attenuation properties of dense bone. The ranges for the other options are indicative of softer tissues or less dense materials. Understanding these nuances in Hounsfield Units is critical for interpreting CT scans effectively.
