• Abstract:

  The pulmonary interstitium comprises the space that contains the connective tissue supporting the parenchyma, as well as the lymphatic network and veins. There are more than one hundred and eighty (180) diseases that can be included in the group of DIPs. Traditionally, they are classified into two large groups: known etiology and unknown etiology. In recent years, several studies have highlighted the value of Computed Tomography in the evaluation of interstitial lung diseases. Recently a beam-shaping energy filter (Silver Beam), which takes advantage of the photon attenuation properties of silver to selectively remove low-energy photons from a polychromatic X-ray beam, has been introduced onto the global clinical stage. The beam shaping energy filter (Silver Beam) proved to be of great value in the clinical routine in chest tomography in patients who have some type of ILD. The use of technology provided high diagnostic quality images, low noise and a considerable reduction in radiation dose when compared to the standard institutional protocol.
