Described herein are compounds, compositions, and methods for diagnosing and/or monitoring pathogenic disease using positron emission tomography. Also described are conjugates of the formula B-L-P, wherein B is a radical of a targeting agent selected from vitamin receptor binding ligands (such as folate), PSMA binding ligands, or PSMA inhibitors; L is a divalent linker comprising aspartic acid, lysine, or arginine, and P is a radical of an imaging agent or radiotherapy agent, such as a radionuclide or radionuclide containing group, or a radical of a compound capable of binding a radionuclide, such as a metal chelating group. 在此描述了用于使用正电子发射断层术诊断和/或监测病原性疾病的化合物、组合物以及方法。还描述了具有化学式B-L-P的共轭物，其中B是选自维生素受体结合配体(诸如叶酸)、PSMA结合配体、或PSMA抑制剂的靶向剂的自由基；L是二价接头，该二价接头包含天冬氨酸、赖氨酸、或精氨酸，并且P是显像剂或放射治疗剂，诸如放射性核素或含放射性核素基团的自由基，或者是能够结合放射性核素诸如金属螯合基团的化合物的自由基。
