Modern CT equipment enables a volume HRCT scan covering the whole lung tissue. HRCT slices can also be construc … High-Resolution Computed Tomography ( HRCT ) is an advanced imaging technique primarily used to obtain detailed images of the lungs. It leverages the principles of computed tomography (CT) but emphasizes fine imaging detail, which is critical for diagnosing and monitoring various lung diseases.
