CategoriesMedical

HRCT stands for High-resolution computed tomography, a medical imaging abbreviation.

Thin-section CT of the lungs, using slices of about 1 mm or less and a sharp reconstruction algorithm, to evaluate interstitial lung disease, bronchiectasis and emphysema. Recognizable patterns such as usual interstitial pneumonia can establish pulmonary fibrosis without a biopsy.

Example: HRCT: basal subpleural honeycombing with traction bronchiectasis, a UIP pattern.

Usage notes

Usually performed without contrast and often with prone and expiratory images, which separate gravity-dependent lung collapse from true disease and reveal air trapping. Modern volumetric scanners produce HRCT-quality images within routine chest CT. Findings are described with Fleischner Society terminology.
