Tc99m-MAA Bronchial Artery Injection During Bronchial Embolization for Pulmonary Mass Induced Hemoptysis for Dosimetry Planning

This research study will evaluate the administration of a particle called macro-aggregated albumin (MAA) labelled with the radiotracer technetium 99m (Tc99m) as a proxy to estimate the anticipated dose of radiation to tumor and adjacent structures. Administration of this labeled MAA will not have a therapeutic benefit on the participant's cancer. Administration will help researchers determine if arterial administration of radiation may be feasible for lung cancer in the future.
