Abstract: Use of a radiolabelled form of 7-chloro-?/?,5-trimethyl-4-oxo-3-phenyl-3,5-dihydro-4/?/?pyridazino[4,5-b]indole-1-acetamide as a biomarker for the detection, in an individual, of PBR levels associated with normal and pathological conditions. Method for the detection of PBR levels associated with normal and pathological conditions. Diagnostic kit.
