1 maj 2021 · A lung opacity is a frequently used term by radiologists on chest X-rays and essentially means a white spot of uncertain significance. The lungs are normally black on a chest X-ray so anything that blocks the X-rays from getting through will look white on an X-ray.

Pulmonary opacification represents the result of a decrease in the ratio of gas to soft tissue (blood, lung parenchyma and stroma) in the lung. When reviewing an area of increased attenuation (opacification) on a chest radiograph or CT it is vital to determine where the opacification is.

23 lut 2023 · Overview. There are 3 major patterns of pulmonary opacity: Airspace filling. Interstitial patterns. Atelectasis. Patterns. 1. Airspace filling. Localized = segmental. Diffuse or multifocal. 2. Interstitial patterns. Reticular—fine or coarse linear shadows. Reticulonodular. Nodular—small (2 to 3 mm), medium, large, or masses (>3 cm) 3. Atelectasis.
3 kwi 2024 · Ground-glass opacification/opacity (GGO) is a descriptive term referring to an area of increased attenuation in the lung on computed tomography (CT) with preserved bronchial and vascular markings. It is a non-specific sign with a wide etiology including infection, chronic interstitial disease and acute alveolar disease.
1 lut 2014 · Lung abnormalities with an increased density - also called opacities - are the most common. A practical approach is to divide these into four patterns: Consolidation. Interstitial. Nodules or masses. Atelectasis. In this article we will focus on this four-pattern approach.
A frontal chest radiograph and axial CT show features of ‘batwing’ alveolar pulmonary edema. Chest radiographic findings include bilateral opacities that extend in a fan shape outward from the hilum in a batwing; pattern. With worsening alveolar edema, the lung opacification becomes increasingly homogenous. Figure 4.
