Clinical Trial Summary

This study investigates the use of hyperpolarized 129Xe magnetic resonance imaging (MRI) in children with primary ciliary dyskinesia (PCD) in detecting ventilation defects. The investigators will establish the feasibility and reliability of this test and how it changes compared to other pulmonary function tests.

Clinical Trial Description

Primary Ciliary Dyskinesia (PCD) is an autosomal recessive inherited disorder caused by defects in ciliary structure and/or function. Prevention or delaying disease progression requires medical therapies and routine lung function monitoring, with the goal of early initiation of medical therapies. Of course, this is contingent on recognizing early lung disease. Current investigations for monitoring lung disease include pulmonary function tests (PFT), chest x rays and chest CTs. But each of these modalities are either not sensitive enough or expose the patient to ionizing radiation. The investigators believe that hyperpolarized 129Xe MRI (HP Xe-MRI), new imaging modality, will be more sensitive then current tests and also avoid the need for ionizing radiation. To evaluate this, The investigators will compare HP Xe-MRI to PFT, when the patient is well and during a pulmonary exacerbation that is being treated. ;
