    • The disclosure relates to a radioisotope-labelled compound having a structure according to formula I, wherein a wavy line indicates a single bond between a non-nodal carbon atom of a polycyclic aromatic system and an R1 substituent selected from a hydrogen; a halogen; a hydroxy; a protected hydroxy; a C1-4 alkoxy; a nitro group; an amino group; an amino group having 1 hydrogen replaced with a C1-C6 alkyl group; an amino group having 2 hydrogens replaced with a C1-C6 alkyl group; an amino group having 2 hydrogen atoms replaced with C2-5 alkylene to form a heterocyclic ring; a chain C1-6 carbon group; a chain C1-6 carbon group having a substituent selected from a halogen, carboxyl, a formyl, and a C1-4 alkanesulfonic; a phenyl group; a phenyl group having 1-5 substituents independently selected from halogens, a chain C1-6 carbon, a halogenated chain C1-6 carbon substituent, a hydroxy, a protected hydroxy, a C1-4 alkoxy, and an amino group having 1-2 atoms of hydrogen replaced with C1-6 alkyl; wherein R2 is a chain aliphatic substituent having: a total of 1-16 carbon atoms, an atom of 18F fluorine radioisotope replacing a hydrogen atom at one of the carbon atoms, and a —CH2 fragment as a terminal member of a chain, wherein the chain connects to one of a hydrogen, a phenyl group, and a phenyl group having 1-3 substituents selected from halogens and C1-6 alkyl, and wherein if the chain contains at least 2 carbon atoms and there is a bivalent link between the chain carbon atoms, then the bivalent link is selected from the group consisting of an oxygen atom —O—, a sulfur atom —S—, and a C3-6 cycloalkylene; wherein R3 and R4 are combined to form a bivalent butadienyl-1,3 substituent whose terminal carbon atoms are linked to adjacent non-nodal carbon atoms of a B ring to form an aromatic C ring fused with an A and B ring system, having R1 substituents at non-nodal carbon atoms; wherein n is an integer of 9; wherein X− is a pharmaceutically acceptable counter ion selected from: an anion of a mono-basic inorganic acid, a mononegative anion of a multi-basic inorganic acid, an anion of an alkane carboxylic acid, an anion of an aliphatic sulfonic acid, an anion of an aromatic sulfonic acid, an anion of an acidic amino acid, a hydrate thereof, and a solvate thereof.
