[ 1 ] - 99mTc-TRODAT-1 SPECT Imaging in Early and Late Onset Parkinson’s Disease

Objective(s): 99mTc-TRODAT-1, which binds to the dopamine transporter, could be used to image the dopaminergic system in diagnosis of Parkinson’s disease (PD). PD can be classified into two groups: late onset Parkinson’s disease (LOPD) and early onset Parkinson’s disease (EOPD). In this study we tried to determine the TRODAT SPECT findings in EOPD as compared to LOPD.Methods: Fifteen patients w...

[ 2 ] - A wandering spleen detected by 99mTc-denatured RBC scan

A 23 day old infant patient underwent 99mTc-denatured RBC scanning for locating possible ectopic spleen in our department.  The scan showed no tracer activity in normal splenic bed in the left upper quadrant and an ectopic spleen was shown on the right side of abdomen inferior to the liver. 99mTc-denatured RBC scan is an easy and available method for splenic localization i...

[ 3 ] - Extra-striatal Uptake of 99mTc-TRODAT SPECT in a Cerebral Meningioma: A Case Report

We reported a 71 years old woman, with history of rest and postural tremor, bradykinesia and memory problems. In her dynamic MRI, a contrastenhanced tumor in the cerebellopontine (CP) angle was found which was compatible with a meningioma. 99mTc-TRODAT SPECT showed decreased activity in the left putamen, indicating idiopathic Parkinson disease. There was also a focus of increased activity on th...

[ 4 ] - Negative 99mTc-MIBI uptake in a parathyroid carcinoma: A case report

A 34 year old woman with malaise, polyuria and nocturia as well as nausea and vomiting referred to perform a thyroid scan due to right thyroid lobe mass. The scan showed a cold nodule in the right thyroid lobe. Serum calcium of 16.9, serum phosphorus of 1.8 and PTH of 1156 were noticed in laboratory tests. Parathyroid scan with 99mTc-MIBI showed no abnormal tracer activity in the nec...
