So I received my hrct scan results of lungs which I guess is a very detailed test and the results were as follows: NO PARENCHYMAL LUNG DISEASE IS IDENTIFIED. NO FINDINGS TO ACCOUNT FOR THE PATIENT'S CLINICAL SYMPTOMS ARE APPARENT. So is this good? Does this mean no serious structural lung damage? Maybe my chest pressure and o2 level dropping is cardiac related? Maybe @dr mannino can provide some input. Thank you
