What does homogeneous opacification mean?

Homogeneous opacification (as a lobar-type pneumonia or as a mass) cavitation is common and can mimic the appearance of a bronchogenic carcinoma focal fibrosis (± contraction) may be severe there are associated pleural effusions, pleural thickening, empyema formation and disease extension into the contiguous soft …

What is inhomogeneous opacity in lungs?

The presence of inhomogeneous lung density in HRCT examination can be result of ground glass opacities, air-trapping, and mosaic perfusion. These signs are visible only on HRCT scans and are involved with gravitational effect and respiratory mechanism.

Is opacity in lungs treatment?

However, recent studies have found that patients with pulmonary ground-glass opacity (GGO) have a better prognosis. Considering its low invasiveness, sublobar resection may be an appropriate treatment of choice. Low-dose computed tomography (CT) is recommended for the high-risk groups of lung cancer.

How do you treat lung opacity?

The current main treatment methods for pulmonary multifocal GGO are forming a troika including the following: surgery, stereotactic body radiation therapy (SBRT), and thermal tumor ablation (including radiofrequency ablation, microwave ablation, and cryoablation).

What is the meaning of opacity in medical terms?

o·pac·i·ty (ō-pas’i-tē), 1. A lack of transparency; an opaque or nontransparent area. 2. On a radiograph, a more transparent area is interpreted as an opacity to x-rays in the body.

What does homogeneous appearance mean?

V2 Vocabulary Building Dictionary Use homogeneous to describe anything that is uniform in appearance or nature, and use heterogeneous to describe things that vary in nature and appearance. Homogeneous can also refer to a mathematical equation in which all of the terms are of the same degree.

What does homogeneous mean in medical terms?

uniform structure
Medical Definition of homogeneous : of uniform structure or composition throughout.

What does opacity mean on chest xray?

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.

What opacities means?

Definition of opacity 1a : obscurity of sense : unintelligibility. b : the quality or state of being mentally obtuse : dullness. 2 : the quality or state of a body that makes it impervious to the rays of light broadly : the relative capacity of matter to obstruct the transmission of radiant energy.

What is opacity in chest xray?

What does an opacity on the lung mean?

Definition. Pulmonary opacity is a nonspecific term describing an area of increased pulmonary attenuation caused by an intraparenchymal process. There are various types of pulmonary opacities, easily categorized as extensive, nodular, reticular, or cystic.

What does opacities in the chest X-ray indicate?

Therefore, an opacity on a chest X-ray in a patient with cough and fever presenting to the emergency room will most likely be a pneumonia. A more rounded opacity in a long time smoker is more likely to be a cancer. White opacities in both lungs in someone known to have heart failure is most likely edema or fluid in the lungs.

What is the difference between non-homogeneous and opacity?

In a simple way of answering your question, non-homogeneous means not the same. So an opacity is a dense material of some kind. So in a frontal view X-ray, you may be looking at a calcification that is angled funny to give it a non homogeneous look. You would need a ct to confirm.

What does modular opacities on a chest radiograph mean?

The radiologist interpreting your chest radiograph saw some modular opacities in at top of the lungs (apices). Bear in mind that the chest radiograph is a 2D representation of a complex 3D structure. This means that overlapping normal structures can appear like abnormalities.

What causes a homogeneous opacity of the lungs?

A homogeneous opacity of both lung fields can naturally also be caused by bilateral pleural effusions. The bilateral effusions may be different in quantity (Fig. 6.29), especially in cardiac decompensation and subsequent pulmonary venous congestion. Do You Know Other Causes for a Diffuse Homogeneous Opacity of the Lung?
