2024年3月8日 · An HRCT (high-resolution computed tomography) scan is a type of CT scan healthcare providers use to get detailed images of your lungs. Providers most commonly use it to diagnose and monitor interstitial lung diseases and conditions that affect your small airways and alveoli (air sacs). What is an HRCT (high-resolution computed tomography) scan?

2024年11月21日 · 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 of 0.5-0.625 mm can be obtained with a sharp reconstruction algorithm on all modern scanners. For interstitial lung disease additional scans are sometimes helpful:

High-resolution computed tomography (HRCT) is a method of examination which is more precise than chest 2-rat in the diagnosis and monitoring of diseases of the lung tissue and the airways. Modern CT equipment enables a volume HRCT scan covering the whole lung tissue.

High-resolution computed tomography (HRCT) is a CT technique in which spatial resolution is optimized. This permits imaging of the fine structure of the lung. For the purposes of this article, HRCT is considered distinct from thin-section CT.

2016年2月27日 · HRCT through the upper lobes demonstrates areas of consolidation in a subpleural and peribronchial distribution in association with areas of ground-glass opacification (left upper lobe).* Biopsy-proven organizing pneumonia.

2006年12月24日 · In this article a practical approach is given for the interpretation of HRCT examinations. Secundary lobules. The centrilobular artery (in blue: oxygen-poor blood) and the terminal bronchiole run in the center. Lymphatics and veins (in red: oxygen-rich blood) run within the interlobular septa.

High-Resolution Computed Tomography (HRCT) refers to a CT scan that gives a more precise cross-section image of the lungs than a regular chest CT and chest X-ray. HRCT Chest uses specific technologies for better image resolution with exquisite lung details ideal for assessment.

2020年5月27日 · 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). It has been classically used for: 1. Sundaram B, Chughtai AR, Kazerooni EA. Multidetector high-resolution computed tomography of the lungs: protocols and applications.

2016年9月3日 · High-resolution computed tomography (HRCT) is widely used in the evaluation of a variety of diffuse lung diseases. The goal of this introductory chapter is to discuss the basics of HRCT, including indications, technique, and normal …

2023年3月23日 · 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. It is a ...
