2014年2月1日 · Atelectasis - collapse of a part of the lung due to a decrease in the amount of air in the alveoli resulting in volume loss and increased density. Here are the most common examples of these four patterns on a chest x-ray (click image to enlarge).
Atelectasis - StatPearls - NCBI Bookshelf
2024年2月26日 · Atelectasis occurs due to the partial or complete, reversible collapse of the small airways, resulting in impaired exchange of CO2 and O2, causing an intrapulmonary shunt (perfusion without ventilation).
Atelectasis - Diagnosis and treatment - Mayo Clinic
2023年11月8日 · A doctor's examination and plain chest X-ray may be all that's needed to diagnose atelectasis. But other tests may be done to confirm the source of symptoms or figure out the type or severity of atelectasis. These tests include: CT scan. A CT may be better than an X-ray at finding the cause and type of atelectasis. Oximetry.

2024年3月5日 · Atelectasis is defined as volume reduction of lung tissue, due to reduced aeration. The clinical significance of atelectasis varies widely depending on the cause, configuration, and severity. For example, a small amount of dependent atelectasis is commonly seen, with minimal clinical significance.
Atelectasis chest x ray - wikidoc
Findings on an x-ray suggestive of atelectasis include displacement of fissures, rib crowding, elevation of ipsilateral diaphragm, volume loss on ipsilateral hemithorax, hilar displacement and compensatory hyperlucency of the remaining lobes.
What Is Atelectasis? - Radiology In Plain English
2022年11月16日 · Atelectasis on chest X-ray will appear as a white area of lung with loss of volume. The normally dark air filled lung will become white and lose volume. It loses volume because it is not filled with air.
Atelectasis - Chest Radiology
Atelectasis is almost always associated with a linear increased density on chest x-ray. The apex tends to be at the hilum. The density is associated with volume loss. Some indirect signs of volume loss include vascular crowding or fissural, tracheal, or …
Atelectasis – Undergraduate Diagnostic Imaging Fundamentals
On x-rays and CT scans, reduced volume is seen, accompanied by increased opacity (chest radiograph) or attenuation (CT scan) in the affected part of the lung. Atelectasis is often associated with abnormal displacement of fissures, bronchi, vessels, diaphragm, heart, or mediastinum. The distribution can be subsegmental, segmental, or lobar.
