PREPARATION AND USE OF ⁶⁸GA-COMPRISING PARTICLES FOR LUNG VENTILATION/PERFUSION AND PET IMAGING AND QUANTIFICATION

摘要

The invention provides a preparation of a ventilation/perfusion imaging agent comprising positron emitting ⁶⁸Ga, produced, from a ⁶⁸Ge/⁶⁸Ga generator. The agent provides high quality images and quantification that make PET examinations available to improve the management of patients under critical conditions such as pulmonary embolism. Assessment of the ventilation distribution is part of the evaluation of lung function prior to lung resection and is also part of the diagnosis of pulmonary emboli.
