“…The tracer is chemically incorporated to a biologically active molecule, typically a substance such as glucose, which can be metabolized by the body cells. [46]. PET produces mainly functional and physiological information; anatomical structures are, in turn, difficult to identify.…”

Stroke has been considered as one of the main causes of death and of motor and cognitive sequels. Especially, many patients with upper limb hemiparesis improved their motor action and showed meaningful cortical changes after treatment with constraint-induced movement therapy. Therefore, this review aims to verify the literature about neuroimaging and behavioral evidences in the cortical reorganization through the use of the constraint-induced movement therapy. So, we conducted the literature research in indexed journals from many databases like Pubmed, Medline, Cochrane Database, Lilacs and Scielo. We concluded that the behavioral and neuroimaging studies using traditional and modified constraint-induced movement therapy promote cortical reorganization.

“…Therefore, in most cases a true representation of biological and physiological processes can be obtained after in vivo administration, generating a molecular image. Hence, the majority of radiotracers are labelled with one of the four common positron emitters carbon-11, oxygen-15, nitrogen-13 and fluorine-18 by replacing the atoms of oxygen, carbon, nitrogen or hydrogen in the compound [49].…”

Positron Emission Tomography (PET) is a diagnostic imaging procedure used regularly to acquire essential clinical information. The PET-CT hybrid, which consists of two scanning machines: PET scanner and an x-ray Computed Tomography (CT). At present these represent the technological hierarchy of Nuclear Medicine, occupying an important position in diagnostics. In fact, PET-CT has the capability to evaluate diseases through a simultaneous functional and morphostructural analysis. This allows for an earlier diagnosis of the disease state which is crucial for obtaining the required information to provide a more reliable prognosis and therapy. Presently, the most frequently used PET radiotracer [ 18 F]fluorodeoxyglucose (FDG) has a major role in oncology. Useful information is being regularly obtained by using both FDG and a selection of radiotracer compounds to evaluate some of the most important biological processes. Thus, creating an opening for 'Molecular Imaging' and providing a platform for a potential revolution in the clinical diagnostic field. In this review, we hope to present the most interesting technicalogical and methodological advances in clinical diagnostics for oncology, neurology, and cardiology. A particular attention is dedicated to the applications of PET in neuropsychiatric diseases and its connections with receptor imaging.

“…Images of metabolic activity in space are then reconstructed by computer analysis, often in modern scanners, alowing to visualize the radiotracer distribution in the body, and subtle changes in physiological performance in vivo (Ribeiro et al, 2007). PET is common imaging modality for clinical use in oncology and in many neurological diseases (Wiebe, 2007;Carter and Kotlyarov, 2007;Lomena and Soler, 2005). A new application for the nuclear imaging techniques is the study of psychological and physiological responses to stress.…”

A new application for the nuclear imaging techniques is the study of organic responses to stress. Neuroimaging techniques allow the assessment of brain activation changes in association with the metabolic responses to stress. In this paper, a review of general effects of the stress on organic activity is made, emphasizing important advances introduced by studies using PET and fMRI. The importance of the hypothalamus-pituitary-adrenal axis to onset the adequate psychical and organic responses to sustain the homeostasis during the stress is discussed, as well as the possibility of traumatic stressing experiences have negative effects on the brain.
