[123I]beta-CIT single-photon emission tomography in DOPA-responsive dystonia.
The radiotracer [123I]beta-CIT is a sensitive marker of dopamine uptake sites that can be used to visualize dopaminergic nerve endings in vivo in the human brain. We report on [123I]beta-CIT single-photon emission computed tomography (SPECT) findings in a patient with DOPA-responsive dystonia (DRD). [123I]beta-CIT SPECT showed a striatal radiotracer uptake in the upper range of normal, indicating intact dopamine transporters and structural integrity of nigrostriatal neurons. This differentiates DRD from clinically similar cases with juvenile-onset parkinsonism with dystonia that have a considerable poorer prognosis. [123I]-beta-CIT SPECT may provide a method equally as useful as fluorodopa positron emission tomography in DRD.
