Nov 21, 2024 · High-resolution CT (HRCT) of the chest, also referred to as HRCT chest or HRCT of the lungs has become routine. With progression of CT scanner technology, slice thickness …

Mar 23, 2023 · Expiratory high-resolution CT (HRCT) imaging corresponds to an additional CT acquisition performed as part of the HRCT chest protocol. It represents a scan performed with the patient on supine and images obtained at the end-expiration.

May 27, 2020 · High-resolution CT (HRCT) is a scanning protocol in which thin sections (usually 0.625 to 1.25 mm) are acquired and reconstructed using a sharp algorithm (e.g. bone algorithm).

May 22, 2024 · A combination of HRCT findings, exposure history, bronchoalveolar lavage lymphocytosis and histopathology can be used to determine the likelihood of hypersensitivity pneumonitis 14.

Jun 19, 2024 · UIP pattern (definite) probable UIP pattern indeterminate for UIP pattern alternative diagnosis This helps radiologists to determine the certainty of usual interstitial pneumonia (UIP) diagnosis based on HRCT chest findings. The importance of this guideline is that (definite) UIP pattern on chest HRCT precludes the need for tissue diagnosis 1,2,5.

Mar 17, 2025 · Cryptogenic organizing pneumonia (COP) is a disease of unknown etiology characterized on imaging by multifocal ground glass opacifications and/or consolidation. A wide variety of infectious as well as noninfectious causes may result in a similar histologic pattern.

Mar 23, 2023 · Prone high-resolution CT (HRCT) chest corresponds to an additional CT acquisition performed as part of an HRCT chest protocol. It represents a scan performed with the patient in a prone position and images obtained in full inspiration.

Feb 5, 2025 · The key differential is the usual interstitial pneumonia (UIP) pattern, with which there can be some overlap in imaging features 3. The features that favor the diagnosis of NSIP over UIP are symmetrical bilateral ground-glass opacities with fine reticulations and sparing of the immediate subpleural space.
