We describe two cases of right hyperglycemia hemichorea (HGHC) with identical Tc-99m TRODAT-1/ Tc-99m ECD scan findings. While the brain MRI showed signal alterations within the left putamen, there was evidence of hyperperfusion on Tc-99m TRODAT-1 but hypoperfusion on Tc-99m ECD within the left putamen, in association with hyperperfusion within left thalamus on Tc-99m ECD. The discrepancy betwe...

Major depressive disorder (MDD) and Parkinson's disease (PD) share symptoms such as tremor. Bupropion, a norepinephrine-dopamine reuptake inhibitor, shows weak dopamine transporter (DAT) occupancy. We report here on a patient with MDD whose hand tremors might have been misdiagnosed as PD by single-photon emission computed tomography (SPECT) under bupropion use. A 66-year-old male patient with M...

Parkinsonism in cerebrotendinous xanthomatosis (CTX) is rare. There are no published studies with imaging findings of dopamine transporter using (99m)Tc-[2-[[2-[[[3-(4-chlorophenyl)-8-methyl-8-azabicyclo [3,2,1] oct-2-yl] methyl] (2-mercaptoethyl) amino] ethyl] amino]-ethanethiolato(3-)-N2,N2,S2,S2]oxo-[1R-(exo-exo)] ((99m)Tc-TRODAT-1) SPECT in CTX patients. This report is on the clinical detai...

Objective(s): To evaluate the role of Tc-99m TRODAT-1 Single Photon Emission Computed Tomography (SPECT) in Parkinson’s Disease (PD) by assessing the correlation of clinical disease severity, disease duration and age at onset of disease with specific uptake ratio of Tc-99m TRODAT-1 in striatum.Methods: The study included 63 patients in age range of 40-72 years with clinical diagnosis of PD and ...

UNLABELLED The aim of this study was to use brain SPECT to differentiate vascular parkinsonism (VP) from Parkinson's disease. METHODS Fourteen VP patients (age range, 59-87 y; mean age, 70 +/- 7.5 y), 30 Parkinson's disease patients (age range, 54-84 y; mean age, 65 +/- 8.8 y), and 26 healthy (control) individuals (age range, 50-85 y; mean age, 60 +/- 9 y) were examined. A 925-MBq (25 mCi) do...

OBJECTIVE Studies of laboratory animals have shown that administration of antidepressants of all pharmacological classes produces changes in dopamine transporter binding affinity. These observations suggest that dopamine transporter function may play a critical role in the pathophysiology of depression. The present study was an examination of the availability of brain dopamine transporter sites...

We evaluated the diagnostic accuracy of SPECT imaging using [(99m)Tc]TRODAT-1 (TRODAT), a relatively inexpensive technetium-labeled dopamine transporter ligand, in distinguishing 29 patients with early PD from 38 healthy volunteers. Mean TRODAT uptake values were significantly decreased in the caudate (p=0.0097) and anterior and posterior putamen (p < 0.0001) of PD patients compared to controls...

Introduction: 99mTc-TRODAT-1 is a promising new radiopharmaceutical with the potential for routine use as the radiopharmaceutical for dopamine transporters scintigraphy as far as its image quality and daily availability are concerned. Here we describe the development of a freeze-dried kit formulation based on the tricine exchange labeling approach for the preparation of this radiopha...
