To examine theeffects on the brain of 2-month treatment withamethylphenidate extended-release formulation (OROS-MPH) using [Tc-] TRODAT-1SPECT in a sample of treatment-naïve adolescents with Attention Deficit/Hyperactivity Disorder (ADHD). In addition, to assess whether risk alleles (homozygosity for 10-repeat allele at the DAT1 gene were associated with alterations in striatal DAT availability.

Parkinson's disease (PD) and Parkinson plus syndromes (PPS) are neurodegenerative movement disorders caused by loss of dopamine in the basal ganglia. The diagnosis of both PD and PPS is complex as it ...
99mTc-TRODAT-1 is a type of drug that can bind to dopamine transporters in living organisms and is often used in SPCT imaging for observation of changes in the activity uptake of dopamine in the stria...
We studied the presynaptic nigrostriatal dopaminergic function using single photon emission computed tomography (SPECT) imaging of a 99mTc-TRODAT-1 (TRODAT) scan in a dopa-responsive dystonia (DRD) f...
Planar whole-body imaging with I-radiolabeled metaiodobenzylguanidine (I-MIBG) is routinely used in the follow-up evaluation of neuroblastoma. In recent years, SPECT with integrated low-dose CT (SPECT...
The diagnostic performance of SPECT-only imaging for takotsubo cardiomyopathy (TC) is limited due to the lack of coronary artery distribution information. The aim of this study was to evaluate the dia...
This study evaluates SPECT image data acquired from Spectrum Dynamics' multi-purpose CZT SPECT camera. All subjects will undergo routine clinical Anger SPECT imaging and an additional SPEC...
This study will examine changes in brain dopamine transporter activity before and after antidepressant therapy.
This is a multiple-center Phase 2 study designed to expand the patient safety and clinical information using 99m Tc-Ec-DG with Spect/CT imaging, to develop procedures and methods for evalu...
An Evaluation of the Safety of Escalating Doses of Tc 99m Tilmanocept by Intravenous (IV) Injection and Skeletal Joint Imaging With SPECT in Subjects With Active Rheumatoid Arthritis (RA) and Healthy Controls
Prospective, open-label, multicenter, dose escalation, safety study of injected Tc 99m tilmanocept in the detection of and assessment of localization to skeletal joints in subjects with an...
This study will use SPECT/CT imaging to assess the effect of percutaneous revascularization treatments in patients with Peripheral arterial disease and diabetes mellitus, in whom the disea...
The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
Longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States during the 1994-95 school year. The Add Health cohort has been followed into young adulthood. (from http://www.cpc.unc.edu/projects/addhealth accessed 08/2012)
A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.
Field of psychology involving the study of normal and abnormal behavior of adolescents. It includes mental processes as well as observable responses.
The study of NUTRITION PROCESSES as well as the components of food, their actions, interaction, and balance in relation to health and disease of children, infants or adolescents.
Psychiatry is the study of mental disorders and their diagnosis, management and prevention. Conditions include schizophrenia, severe depression and panic disorders among others. There are pharmaceutical treatments as well as other therapies to help...
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
