Ventilation—perfusion study was performed in fifteen subjects with the provisional diagnosis of bronchiectasis. Ventilation study was done by radioaerosols and perfusion by radiolabelled human serum albumin (HSA) microspheres. Abnormal aerosol-perfusion scans were observed in all the cases. The bronchographically proved bronchiectatic segments were found to be represented by matched ventilation—perfusion defects conforming to bronchopulmonary segmental anatomy on scans in all cases. Although definite diagnosis of bronchiectasis was possible only by bronchography, additional information regarding the extent of the disease and associated chronic obstructive airways disease by V/Q scanning was helpful in selecting suitable candidates for surgery.
