High Resolution Computed Tomography

  • 12th May, 2021
  • 'High Resolution Computed Tomography' (HRCT) is a type of CT scan with specific techniques to enhance image resolution. It is used in the diagnosis of various health problems, most commonly lung diseases.
  • CT scans are more detailed than general X-rays, showing detailed images of any part of the body, including the bones, muscles, fat and organs. Internal organs, bone, soft tissue and blood vessels provide greater clarity and reveal more detail than regular X-rays.
  • HRCT is performed using a conventional CT scanner. Imaging parameters are chosen so as to maximize spatial resolution. The technique of HRCT was developed with relatively slow CT scanners, which didn't make use of multi-detector technology.
  • High Resolution Computed Tomography is used for diagnosis and assessment of interstitial lung disease such as pulmonary fibrosis, and other generalized lung diseases such as emphysema and bronchiectasis. These are the airways diseases.
