Since the division of the lobes and segments of the lung on CT scan is limited to its relations with the structures of the pulmonary hilum and the interlober fissures, we attempted to put the division on the anatomical basis of segmental structures. The topographicul relationship of the ...
Similarly the volume, alveolar ventilation and effective blood flow of lobes and segments can be determined by simple single-breath manoeuvres at bronchoscopy using a respiratory mass spectrometer. The radio-isotope and spectrometric tests can be obtained in the same breath. The spectrometric tests can...
results are then superimposed to 2D views in standard colors: "Bulla" = black, "Inflated" = blue, "Infiltrated" = yellow, "Collapsed" = pink and "Vessel" = red. In addition, spatial reconstruction (3D) of the diseased lung segments is available. The total results of the segmentation ...
Lung density and attenuation are partially determined by the volume of blood present within pulmonary vessels. Thus, regional differences in lung perfusion in patients with airways disease or pulmonary vascular disease can result in in...
The lungs are made up of lobes, with two on the left and three on the right. Each lung lobe is divided into small branches called lung segments. The technique uses 3D computed tomography, which allows doctors to conduct more precise surgeries under a thoracoscope and thus preserve more heal...
Segments, lobes, or an entire lung are no longer aerated and undergo partial (dystelectasis) or complete collapse (atelectasis). This is manifest as patchy or homogeneous pulmonary opacification of lobar or segmental distribution. Right upper lobe atelectasis left upper lobe atelectasis Left low ...
Lung cancer is considered more serious among other prevailing cancer types. One of the reasons for it is that it is usually not diagnosed until it has spread and by that time it becomes very difficult to treat. Early detection of lung cancer can signific
and mathematical shape correspondence between subjects, anatomical landmarks were placed at the lung apices, dome of the diaphragm, the edge of the lung base, and the edge of anterior segments. Additional pseudo-landmarks were regularly-spaced between these points. The generic mesh was ...
mosaic perfusion or mosaic oligemia, although the former term is most appropriate. This can result from airways or vascular disease. Areas of relatively decreased lung opacity seen on HRCT can be of varying sizes and sometimes appear to correspond to lobules, segments, lobes, or an entire lung...
