Crude SRP or radiolabelled ones showed the same aerodynamic size distribution and output as a conventional molecular tracer, as sodium fluoride. With MR and GC imaging approaches, the nebulised dose represented about 50% of the initial dose of nanoparticles placed in the nebuliser. Results expressed as proportions of the deposited aerosol showed approximately a regional aerosol deposition of 50% of the deposited dose in the lungs and 50% in the upper airways. Each technique assessed a homogeneous pattern of deposited nanoparticles in Lungs. MR observed a strong signal enhancement with the SRP, similar to the one obtained with a commonly used MRI contrast agent, gadoterate meglumine.Conclusion: As a known theranostic approach by intravenous administration, SRP appeared to be easily aerosolised with a conventional nebuliser. The present work proves that pulmonary administration of SRP is feasible in a human-like model and allows multimodal imaging with MR and GC imaging. This work presents the proof of concept of SRP nebulisation and aims to generate preclinical data for the potential clinical transfer of SRP for pulmonary delivery.Keywords: aerosol, pulmonary delivery, ex vivo model, MRI, SPECT/CT, theranosticMontigaud YPourchez JLeclerc LTillement OClotagatide ABal CPinaud NIchinose NZhang BPerinel SLux FCrémillieux YPrevot NDove Medical Pressarticleaerosolpulmonary deliveryex vivo modelmrispect/cttheranosticMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 15, Pp 7251-7262 (2020)
