Consolidation is defined as increased pulmonary opacity with obscuration of bronchial and vascular margins (as opposed to ground-glass opacity, in which such structures are visible through the lung opacity). Radiologists can readily identify pulmonary consolidation. However, it is included here to highlight consolidation as an imaging ...

2023年11月23日 · Chronic obstructive pulmonary disease (COPD) often leads to hyperinflated lungs. COPD is a long-term lung disease that makes it hard for air to flow in and out of the lungs. The two most common forms of COPD are emphysema and long-term bronchitis. Often the two conditions happen together.

2023年11月8日 · Overview. Atelectasis (at-uh-LEK-tuh-sis) is the collapse of a lung or part of a lung, also known as a lobe. It happens when tiny air sacs within the lung, called alveoli, lose air.

2002年8月1日 · Consolidation in the lung is seen on radiographs or computed tomography (CT) as increased areas of attenuation that obscure the underlying pulmonary vasculature. There are numerous causes of multifocal consolidative opacities. If the symptoms are acute (days to weeks), the most common causes include edema, pneumonia, and hemorrhage.

2020年11月1日 · Pulmonary consolidation is a non-specific pattern on computed tomography (CT) that is mostly due to acute pulmonary infection [1]. Consolidation is considered to be persistent when the opacity has failed to resolve by 50% in 2 weeks or completely in 4 weeks [1].

1996年4月1日 · The information of spectral wave analysis is helpful for understanding the underlying etiology of a pulmonary consolidation. Color Doppler US is useful in assessing the perfusion and reperfusion status of a pulmonary infarction. There are still other potential applications of this new technique in chest diseases that may need further exploration.

2008年1月1日 · Diffuse alveolar hemorrhage (DAH) with or without pulmonary capillaritis is the main pulmonary manifestation. 9, 13, 14 A small-vessel vasculitis causing DAH is reported in 10–30% of patients with MPA. 9 Pulmonary interstitial fibrosis can also be an initial manifestation of MPA and seems to be associated with a poorer prognosis. 15 Other ...

2000年1月1日 · Introduction. Pulmonary consolidation, which is frequently encountered in chest diseases, can have various causes, such as the filling of the air-space with fluid, as in simple pneumonia, obstructive pneumonia, pulmonary hemorrhage and pulmonary infarction, or with solid materials as in tumor consolidation.

1997年1月1日 · The distal flow resistance is lower in pulmonary vessels in cases of tumor consolidation than those with simple pneumonia. This characteristic "low-resistance tumor flow" indicates the presence of abnormal neovasculari- zation, which is frequently found in malignant tumors (Civardi et al. 1993; Yang 1996).
