AI Article Synopsis

  • HRCT (High-Resolution Computed Tomography) is acknowledged as a valuable tool for assessing diffuse lung diseases, particularly in identifying ground-glass opacity (GGO) but has limitations in evaluating detailed lung tissue changes.
  • The author categorized GGO into four distinct patterns and emphasized its relevance in the context of interstitial pneumonia, alongside discussing the "crazy-paving appearance."
  • The study also compares the imaging capabilities of 0.5 mm HRCT with Multidetector CT and introduces advanced imaging techniques like micro-CT and synchrotron radiation CT for lung assessments.

Article Abstract

The usefulness of HRCT in diffuse lung disease has already been established. However, it is not sufficient to evaluate the pathological changes of pulmonary parenchyma, often seen as ground-glass opacity(GGO). The author reviewed GGO, classified into four patterns, in light of each subject's pathological background, especially for interstitial pneumonia. Crazy-paving appearance was also reviewed. The imaging ability and usefulness of 0.5 mm HRCT were examined and compared with Multidetector CT. Finally, imaging with micro-CT and synchrotron radiation CT is discussed.
