With regard to the accuracy of visual evaluation, on comparing the difference in overlapping among original images with the difference in overlapping between warped moving and fixed images, we found that the later overlapping images showed exactly aligned lung volumes, with a well-matched lung boundar...
Lung volumes refer to a measured amount of air which enters or leaves the lungs during specific breathing maneuvers. Tidal volume is the amount of... See full answer below.Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our expert...
PFT- The pulmonary function testing system allows for a comprehensive assessment of the lungs. All lung volumes and spirometry equivalent test results are completed in a matter of minutes; allowing for high throughput and quicker results.

Thevalues comparing the total lung volumes on expiratory CT in the supine/standing/sitting positions and the functional residual capacity on PFT were 0.83/0.85/0.82, respectively. Thevalues comparing the total lung volume changes from expiration to inspiration on CT in the supine/standing/sitting ...
the inflammatory response of the lung can be quantified by measuring inflammatory markers.11–13Lung function measurement in preterm infants onrespiratory supportis still restricted to research protocols despite major progress in equipment technology.14The measurement of lung volumes such asfunctional residua...
simple and vital first step in preoperative assessment is the chest CT scan, which the patient would have already received. This can be used to count the number of lung segments, determine the extent of surgery required (ie, lobectomy versus pneumonectomy), and predict postoperative lung volumes...
Obstructive lung disease: When there is an obstruction of airflow, the path of air becomes halted earlier than expected at high lung volumes. This condition leads to trapped air in the lungs. Compliance can be normal or increased. PFTs usually reveal a low FEV1/FVC ratio as FEV1 is reduced...

These three GLI equations (spirometry, DLCO and lung volumes) are internally consistent, providing a single suite of PFT equations which will avoid discordant results between PFTs and potential misclassification of physiological phenotypes. The GLI equations include the largest samples of healthy ...
PFT An MRI-compatible spirometer was used to standardize lung volumes and breathing movements during the MRI (MasterSceen Pneumo spirometer, CareFusion, Houten, the Netherlands). Before MRI, FVC and forced expiratory volume in one second (FEV1) were measured according to ATS/ERS standards [23,24...
