Magnetic resonance imaging

direct cause of jaundice then axial imaging such as computed tomography (CT) or magnetic resonance imaging (MRI) will be performed. Tumors can be identified and staged by endoscopic studies determined by where the lesion is. If the lesion is within the proximal biliary tree then a percutaneous transhepatic cholangiography (PTC) can be used. If the lesion is within the distal biliary tree, endoscopic ultrasound (EUS) should be used. Ultimately, no matter what imaging technique is used, true…

Schizophrenia is a life-threatening disease that affects one's thinking, perception, personality, and behavior. Schizophrenia develops from neurotransmitters such as serotonin and dopamine, which affect the brain. This disorder is diagnosed by CT scans and MRI’s that may show the brain and why patient’s symptoms are caused. Some patients with schizophrenia develop symptoms like sleep apnea, hallucinations, delusions, problems with emotions, making decisions, and more. Symptoms are divided into…

episode. Here, patient also stated he refused for any treatment after first recovery because he has very good recovery first time. Fuller, (2015), point out that history of stroke increase 5% risk of reoccurrence within 3 years. Thus, timely manner imaging techniques such as MRI or functional MRI, is helpful to detect soft tissue changes after first episodes to current…

Chapter two, “The Neuroscience of Learning and Memory”, was an overview of how our brain functions and how it is developed. Neuroscience is the study of the brain and the rest of the nervous system. Reading through the section of what brains are like, it was interesting the difference between the Central nervous system and the Peripheral nervous system. The Central nervous system only consists of the brain and the spinal cord, but the Peripheral nervous system consists of motor and sensory…

Overview Stroke and hemorrhagic stroke A stroke is a brain attack. It is caused when blood flow to an area of brain is cut off. Brain cells are deprived of oxygen and begin to die. After that, abilities for the brain cells in that area to memory and muscle control are lost. There are two main kinds of strokes: ischemic stroke and hemorrhagic stroke. Ischemic stroke is the main kind of strokes and it takes up to 80% of all strokes. It is caused by a blockage of blood flow of part of the brain…

Catching Cancer Early Do you aware about the most dangerous and deadly diseases that exist in our life? Surely, there are many terrifying diseases that attack people and lead to the death such as HIV (Human Immunodeficiency Virus), Ebola, and Cancer. Therefore, this essay is going to inform you about the most risky disease which is cancer, the causes and the symptoms of cancer, and about the new technology or way which use to detect or catch cancer. What is Cancer? Cancer is known as the most…

multiple sclerosis, Alzheimer's disease, headaches, stroke, or injury (Webmdcom, 2015)." Neurologist are certified by the Board of Psychiatry and Neurology. "A neurologist can order or interpret tests such as a computed tomography (CT) scan, magnetic resonance imaging (MRI), or lumbar puncture to diagnose problems and may conduct tests to evaluate how well a nerve or muscle is working. A neurologist can prescribe medicines to treat diseases or may refer a person to another specialist if needed…

thinking, and other cognitive processes. (Ciccarelli & White, 2005.) The neuroscientists that study this field of cognitive perspective use tools that image the structure and activity of the living brain for example, the magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and positron emission tomography…

to the diagnosis of child abuse, and a more aggressive approach toward the identification and prosecution of offending individuals. Radiologic imaging plays a key role in the diagnosis of child abuse. The imaging has evolved with the advent of nuclear medicine, ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI). These imaging modalities helps to provide evidence for the prosecution or defense of offenders by understanding…

normal state, even in the absence of a headache the cerebral cortex, mainly the occipital cortex of a migraineur’s brain is in a state of hyper excitability. These findings are proven in studies involving transcranial magnetic stimulation with functional magnetic resonance imaging (MRI). This finding justifies the distinctive vulnerability of the brain of patients with migraine to headaches. The cortical spreading depression (CSD) theory defines the process involving in MA. CSD is a precise…
