[High-resolution computed tomography of the lungs in pediatric XXXX ].

Since the introduction of the high-resolution technique more than ten years ago, HRCT has become an established modality for diagnosing @entity17220 . This is especially true for the diagnosis of @entity358 in adults. Experience in HRCT of the lungs is limited in pediatric @entity1 . This review gives an overview of frequent and less frequent HRCT findings in @entity358 in childhood. A purely reticular pattern is rarely observed in @entity1 . @entity358 associated with overinflation are relatively frequent. Paired inspiratory-expiratory scans combine morphological analysis with functional information and have improved the diagnosis of air trapping, e. g. in post-infectious @entity4154 or @entity2107 . Especially in @entity1 the high radiation exposure is a problem. Even when applying a low-dose protocol the radiation dose of HRCT will still exceed the dose of a chest X-ray by 100 times. The indication for pediatric @entity358 is limited to selected cases and it should be decided in agreement with the pediatric radiologists and the pediatric pulmonologists.
