PURPOSE: To assess the presence and extent of @entity2874 ( @entity2874 ) on chest high-resolution CT (HRCT) in @entity370 and to correlate such findings with patterns, lesion extent on inspiratory CT and pulmonary function tests (PFT). MATERIAL AND METHODS: Thirty @entity1 with @entity370 underwent inspiratory and expiratory HRCT and PFT. HRCT images were evaluated for presence, distribution and @entity2874 extent as well as the predominant HRCT pattern and the extent of lesions at inspiration. Attenuation difference in the @entity2874 regions at expiration and at inspiration were calculated. The presence and extent of @entity2874 were correlated with PFT, extent of involvement and predominant inspiratory patterns. RESULTS: @entity2874 was present in 25/30 @entity1 with no lung zone predilection. @entity2874 was the only CT indication of @entity10070 in 3/30 @entity1 who also had normal PFT. Attenuation difference between inspiration and expiration ranged from -40 HU to 106 HU. In 2 @entity1 , a paradoxical @entity536 was observed at expiration. A significant correlation was found between @entity2874 extent at expiration, with residual volume-total lung capacity ratio and residual volume. CONCLUSION: @entity2874 is an additional HRCT finding in @entity370 . @entity2874 may involve any lung zone, including @entity5513 and may be the only CT feature of @entity10070 . Strong correlation is only found with PFT values that are specific for incomplete lung emptying at expiration.
