The phrase "air lung" is not correct and does not have a clear meaning in written English.
It is not a standard term and may cause confusion, as it does not refer to a recognized concept or object.
Example: "The doctor explained that the air lung is a fictional device used in the story."
Alternatives: "respiratory system" or "lung capacity".
These MRAC attenuation maps include air, lung, fat, and soft tissue attenuation coefficients.
The Philips Ingenuity TF PET/MR Philips International B.V.., Amsterdam, The Netherlands) uses a T1-weighted image acquisition for three-class tissue separation (air, lung, tissue) and body delineation [1], whereas the Siemens Biograph mMR (Siemens AG, Erlangen, Germany) uses a two-point Dixon MR sequence to separate the tissues in four classes (air, lung, fat and soft tissue) [2]-[4].
Commercially available systems often employ correction schemes based on segmenting the body into different tissue classes (air, lung tissue, fat-, and water-like soft tissue), e.g. by using a dual time-point Dixon sequence.
A standard two-point Dixon sequence (pre-Gadolinium) was performed for AM generation, resulting in AM images of four different tissue classes (air, lung, fat-, and water-like soft tissue).
The standard procedure implemented for the Siemens Biograph mMR scanner (Siemens Healthineers, Erlangen, Germany) is based on MR-based segmentation of different tissue classes (air, lung, fat, water; ±bone for brain imaging) and voxel-wise application of typical attenuation values.
All voxels in the field of view were classified into one of the four tissue compartments air, lung, fat, and water in order to provide an attenuation map of the volume covered by MRI.
Attenuation maps (AM) were generated from MR data (standard Dixon sequence-based segmentation of air, lungs, fat-, and water-like tissue).
Moreover, New Delhi's mature trees improve air quality by filtering city air: Lungs of Delhi and parks absorb 85percentt of air pollution and city trees by as much as 70percentt.
In addition, Equation 2 has one weakness, as remaining body volume (VT) is obtained by subtracting plumage air volume (VFs) and respiratory air (lungs + air sacs) volume (VLs) from total body volume (VB).
Make sure the machine detected alveolar air (lungs) as opposed to mouth alcohol.
The pulmonary surfactant is a protein-lipid mixture that spreads into a film at the air-lung interface.
