What is basal area of lung?
portion of a structure which forms its base-the bottom part or part opposite the apex of the structure-or a branch serving that portion of the structure; e.g., the basal part of the lungs (formed by the four basal bronchopulmonary segments of each side) served by basal parts of the right and left pulmonary arteries.
What are lung fields?
Lung field defines a region-of-interest in which specific radiologic signs such as septal lines, pulmonary opacities, cavities, consolidations, and lung nodules are searched by a chest radiographic computer-aided diagnostic system. Thus, its precise segmentation is extremely important.
What are the lungs posterior to?
Anteriorly it is related to the sternum, and posteriorly it is related to the vertebra. The diaphragmatic surface (base) is concave and rests on the dome of the diaphragm; the right dome is also higher than the left dome because of the liver. The right and left lung anatomy are similar but asymmetrical.
What does lung fields are clear means?
• Normal CXR – A normal chest X-ray means clear lung. fields and no abnormality detected. Participants with. normal CXR have no radiological basis for undergoing bacteriological examination.
Which aspect of the lung is known as the apex?
The cardiac notch is an indentation on the surface of the left lung, and it allows space for the heart (Figure 1). The apex of the lung is the superior region, whereas the base is the opposite region near the diaphragm.
What are the four lung fields?
The areas of the lungs that can be listened to using a stethoscope are called the lung fields, and these are the posterior, lateral, and anterior lung fields.
How many lung fields are there?
The left and right lung are divided into six lung regions marked (a) to (f). Lung region (a-c) correspond to upper, middle and lower lung field of the right lung, and region (d-f) correspond to upper, middle and lower lung field of the left lung, respectively.
Are the lungs posterior to the ribs?
“the lungs are deep to the rib cage.” close to the origin of the body part or the point of attatchement of a limb to the body trunk. “The elbow is proximal to the wrist.” farther from the origin of a body part or the point of attachement of a limb to the body trunk.
What are the different basal segments in the right lung?
In the Right Lung 1 Superior segment. 2 Medial basal segment. 3 Anterior basal segment. 4 Lateral basal segment. 5 Posterior basal segment .
What is the anterior margin of the left lung?
ANTERIOR BORDER – 1. Corresponds to the anterior (Costomediastinal) line of pleural reflection. 2. It is deeply notched in the left lung posterior to 5thcostal cartilage by the pericardium costal cartilage by the pericardium and extends vertically downwards to form
What are the different parts of the right lung?
Right lung 1 right upper lobe apical segment (B1) posterior segment (B2) anterior segment (B3) 2 right middle lobe (or more correctly – just middle lobe) lateral segment (B4) medial segment (B5) 3 right lower lobe superior segment (B6) medial segment (B7) anterior segment (B8) lateral segment (B9) posterior segment (B10)
What are the different lobes of the lungs?
Bilaterally, the upper lobes have apical, posterior and anterior segments and the lower lobes superior (apical) and 4 basal segments (anterior, medial, posterior and lateral). With this basic symmetric anatomy shared between the lungs, there are a few differences that can be described:
