About

Gallium-68 DOTATATE is a radioactive tracer, a type of imaging drug that is labeled with a radioactive tag and injected into the body, which is approved by the U.S. Food and Drug Administration (FDA) to diagnose certain tumors. The study will see how the tracer is taken up in your heart before and after treatment using an imaging scan called Positron Emission Tomography / Computed Tomography (PET/CT). Investigators are doing this research study to find out if DOTATATE can help doctors diagnose people with cardiac (heart) sarcoidosis better as well as serve as a follow-up monitoring tool for a response to therapy.

    1. High degree A-V nodal block
    2. Complete bundle branch block
    3. Reduced left or right ventricular systolic fusion
    4. Any cardiac arrhythmia
    5. Chest pain, dyspnea or syncope without clear etiology

  3. Currently taking the medication Octreotide
  4. Currently on total parenteral nutrition (TPN)
  5. Inability to tolerate imaging procedures in the opinion of an investigator or treating physician
  6. Any current medical condition, illness, or disorder as assessed by medical record review and/or self-reported that is considered by a physician investigator to be a condition that could compromise participant safety or successful participation in the study
