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...
متن کاملIncidental detection of probable meningioma in brain scintigraphy using 99mTc-TRODAT-1.
An 84-year-old woman underwent a dopamine transporter (DAT) study to investigate a non-levodopa-responsive parkinsonism. A SPECT brain scan was conducted four hours after intravenous administration of 1110 MBq (megabecquerels) equivalent to 30 mCi (millicuries) of 99mTc–TRODAT-1. The study revealed a significant uptake deficit of radiopharmaceuticals in the striatum. The semi-quantitative analy...
متن کاملDiagnostic accuracy of [99mTc]TRODAT-1 SPECT imaging in early Parkinson's disease.
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...
متن کاملExtra-osseous 99mTc methylene diphosphonate uptake detected enlargement of the knee joint in patient with polyarthritis
Bone scintigraphy is a nuclear scanning test used to find abnormalities in the skeleton. Certain abnormal processes involving soft tissues can also cause skeletal accumulation of radiotracer during bone scintigraphy. We present a case of periarticular knee soft tissue 99mTc methylene diphosphonate uptake in a patient with asymmetric polyarthritis. A 33-year-old patient with asymmetric polyarthr...
متن کاملFully Automated Quantification of the Striatal Uptake Ratio of [99mTc]-TRODAT with SPECT Imaging: Evaluation of the Diagnostic Performance in Parkinson's Disease and the Temporal Regression of Striatal Tracer Uptake
PURPOSE We aimed at improving the existing methods for the fully automatic quantification of striatal uptake of [(99m)Tc]-TRODAT with SPECT imaging. PROCEDURES A normal [(99m)Tc]-TRODAT template was first formed based on 28 healthy controls. Images from PD patients (n = 365) and nPD subjects (28 healthy controls and 33 essential tremor patients) were spatially normalized to the normal templat...
