Spectral Computed Tomography (CT): A Clearer Way to See Inside the Body
Spectral Computed Tomography (CT), often called dual-energy CT or multi-energy CT, represents one of the most important advancements in modern diagnostic imaging. While traditional CT scanners measure the total X-ray attenuation passing through tissues, spectral CT takes this a step further by separating the X-ray beam into different energy levels. This gives radiologists a deeper, more detailed look at the composition of tissues, materials, and abnormalities inside the body.
At the core of spectral CT is the idea that different substances absorb X-rays differently depending on the energy of the beam. For example, calcium, iodine, and soft tissues each have unique energy-dependent signatures. By capturing data at multiple energy levels, a spectral CT scanner can distinguish between these materials with far greater accuracy than conventional CT. This results in clearer images, fewer artifacts, and more precise information about…
