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

Tc99m-MAA is a particle that is used to assess blood flow distribution and has a similar size to the particles that are utilized for arterial delivery of radiation therapy, also called radioembolization. Tc99m-MAA is currently used to estimate radiation dosimetry prior to arterial radiotherapy administration for liver malignancies.
