1) Its cause could be edema, cells like neutrophils or even early changes of fibrosis in which the underlying pulmonary alteration is below the limit of resolution
of the HRCT image.
As the calculated angular separation--19 arcseconds--doesn't change in the time error interval, it is very relevant because it indicates quite precisely the limit of resolution
Next, let us consider a superior limit of resolution
assuming the use of the steepest curve in Fig.
