The aim was to describe lung perfusion SPECT (LPS) findings in children with chronic pulmonary damage. Material and Method: We revised 106 LPS of children (age:3.9 ± 3.3 yr) with chronic pulmonary damage, performed with a two headed gammacamera. The most common clinical diagnosis were adenovirus bronchopneumonia sequelae (ADV)(29%), unknown origin chronic pulmonary damage (UOPD) (21%), bronchopulmonary dysplasia (BPD)(15%), and chronic obstructed bronchitis (COB)(14%). Severity of pulmonary

Pattern of involvement and Score were correlated with diagnosis and gender. Results: Ninety one percent (96/106) of LPS were abnormal (62% boys). Fifty two (54%) showed bilateral alterations, being this finding (p:0.019) more frequent in boys. ADV group showed mainly a mixed bilateral pattern (35%), UOPD a focal unilateral pattern (32%), COB a diffuse unilateral pattern (33%), and BPD a normal pattern (25%). Miscellaneous and UOPD showed the highest score values, and BPD and COB the lowest ones. Conclusion: In this population, LPS is abnormal in high proportion, with some differential characteristics according gender and original diagnosis.
