Mitochondrial ImagingImaging Mitochondrial Complex-I in Cocaine Use Disorder: a [F-18]BCPP-EF PET Study

Cocaine use disorders (CUD)

1. Males or females between 18 and 45 years old.
2. fulfill DSM-5 criteria for moderate or severe (4+ criteria) cocaine use disorder.
3. No lifetime DSM-5 schizophrenia, schizoaffective disorder, bipolar disorder, and developmental disorders.

6. Not currently on psychotropic or medical medications that can influence binding to MC-I (e.g., metformin) or CGM (e.g., insulin, GLP-1 agonists), or increase the risks associated with an arterial line (e.g., warfarin, clopidogrel, aspirin, naproxen, ibuprofen, etc.).
7. No comorbid medical disorders that can influence the PET outcome measures (for example, MC-I binding is altered in Parkinson' disease, mild or major neurocognitive disorders, mitochondrial disorders, immune disorders; and CGM is altered in diabetes, severe hyperlipidemia, hypertension, obesity), or are a contraindication for blood sampling (anemia), or placement of an arterial line (history of deep vein thrombosis, pulmonary embolism, thrombocytopenia or thrombocytosis).
8. Not currently pregnant or breast-feeding.
9. Not currently employed as radiation worker; or has not participated in a radiation-related research protocol within the previous year such that the total cumulative annual radiation dose (i.e., from participation in previous radioactive drug studies and this study) would exceed the radiation dose limits specified in the FDA regulations (i.e., 21 CFR 361.1) that govern the research use of radiotracers.
10. No medical or psychiatric contraindications to undergo an MRI scan (such as ferromagnetic tattoos/piercings, implants, medical equipment, history of gunshot, and claustrophobia).

Healthy controls (HC)

1. Males or females between 18 and 45 years old.
2. No DSM-5 psychiatric or substance use disorder other than tobacco use disorder
