Functional magnetic resonance imaging

MRI is a medical imaging technique used to visualize detailed internal structures of the body and makes use of the property of nuclear magnetic resonance (NMR) to image nuclei of atoms inside the body. MRI is used over other medical imaging techniques, such as computed tomography (CT) or X-rays, since it provides contrast between the soft tissues of the body, making it especially useful in imaging the brain. Additionally, CT is considered to be unhelpful in cases of intractable epilepsy [29]. Conventional

see what they see, and what they think. Until recently, this hope was just that, a dream. But now, using magnetic resonance imaging, statistical analysis programs, and a new encoding model, scientists have turned this dream into a reality. MRIs use strong magnetic fields to trigger and measure a charge in the tissue scanned, which is then translated to an image of the scanned area. Functional MRIs expand on this technique by using the change in charge in specific parts of the brain to measure the

considering an accuracy of the polygraph test in order to detect deception that has limitation. Deceit detection should be more reliable by evaluating the function of the brain individually correlated to lying (Kozel et al, 2005). Functional magnetic resonance imaging (fMRI), the medical instrument, was altered to complete the missing pieces of the scientific puzzle. If fMRI can meet the standards of legal reliability, it will be the new aspect of lie detection (Langleben and Moriarty, 2013). The

According to Klein (2010) functional neuroimaging technologies, such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), have revolutionized neuroscience, and provided crucial tools that link cognitive psychology and traditional neuroscientific models in the diagnosis and treatment of brain disorders (Klein, 2010; Sabb & Bilder, 2006). Neuroimaging refers to a collection of techniques that allow scientists to investigate the functions of the brain through the detection

(40 mg/m 2). Response assessment and brachytherapy preplanning MRI were performed within a week of completing IG-IMRT. Subsequently, all patients underwent template guided high dose rate pelvic interstitial brachytherapy (20 Gy/5 #/ 3 days). MR Imaging Methodology: MRI protocol was standardized in all cases. MRI was performed on the 3.0-T system (GE Signa 3.0T HDx, GE Healthcare, Milwaukee, WI) using a torso phased-array with the patient in the supine position. We approximately used 60 ml of bacteriostatic

that allow a better understanding of the brain. Methods like Magnetic Resonance Imaging (MRI) offer to the scientists the capability of exploring the brain from a deep perspective combining both a good spatial and time resolution (Nelson, 2008). Furthermore, the MRI images not only allow the study of the anatomy of the brain (i.e. structural images), but also the activation of different areas when a task is being performed (i.e. functional MRI). For example MRI images can be utilized to do comparisons

Abstract BACKGROUND: autism is a pervasive developmental disorder of children, characterized by impaired communication, excessive rigidity, emotional detachment and neurological disorders.it involves delaying in many basic skills. Autism appears at the age of breastfeeding or before the child reaches the age of three.many autistic children have attention defect and dificultis in concentration. What are the brain abnormalities in autistic individual cause lack of attention? Many studies found abnormalities

One of the principal problems for defining and diagnosing concussion, is that there is not a universally acceptable definition for concussion. In the article, the author refers to concussion as a “mild traumatic brain injury (MTBI) that results in a temporary loss of neurologic function without apparent structural damage, and may or may not involve loss of consciousness (LOC)” (Mennella, 2016). Concussions are considered a great concern in healthcare because according to the Center for Diseases

advantage of not requiring surgical intervention. An example of this scientific observation is in the work of (Parvizi et al 2011): who in their analysis of one hundred patients using EEG (Electroencephalogram) video monitoring and MRI (Magnetic Resonance Imaging), where able to confirm, “Regardless of the type of seizures (gelastic epilepsy-only or gelastic epilepsy-plus), or the presence of precocious puberty or cognitive impairment, we found no correlation between the duration of disease and the

maintaining their viability. Several imaging technologies are being utilized to progress stem cell therapies. Such modalities include “positron emission tomography (PET), computed tomography (CT), single photon emission CT (SPECT), ultrasound (US), bioluminescence imaging (BLI), fluorescence imaging (FLI), [and] magnetic resonance imaging (MRI),”(Cho, Wang, Mao, & Chan, 2016) while “MRI and PET are the most widely investigated and developed”(Cho et al., 2016). Each imaging modality has their own advantages
