Bipiperidinyl compounds and salts thereof are disclosed. The compounds include high affinity ligands for σ
1
receptors. Some compounds are also highly selective for σ
1
receptor compared to σ
2
receptor. Compounds can comprise radioisotopes, including
18
F or
11
C. Radiolabeled compounds can be used as probes for imaging distribution of σ
1
receptor in a subject such as a human using positron emission tomography (PET) scanning.
