What is the CT number associated with clotted blood?

50

60

70

75

The CT number associated with clotted blood is generally around 75 Hounsfield units. The Hounsfield scale is used in computed tomography (CT) to measure radiodensity, with water set at 0 Hounsfield units and air at approximately -1000. Different tissues and materials show distinct density levels due to their elemental composition and structure, and these densities are reflected through varying CT numbers.

Clotted blood has a composition that includes proteins and cells, leading to a higher density compared to plain water but not as dense as bone or calcified structures. This is why the CT number for clotted blood is reasonably high, around 75. Understanding this value is crucial for radiographers as it aids in differentiating clotted blood from other tissues in CT imaging, allowing for more accurate diagnosis and treatment planning.
