Positron Emission Tomography Analysis

Words: 160

Pages: 1

Positron emission tomography, (PET), is an invasive brain imaging method. It involves injecting a patient with a radioactive isotope and this then accumulates in blood vessels within the brain. When this part of the brain is activated, the radioactive isotope moves quickly to that area. The positrons emitted from this are measured by a scanning machine. A computer system analyses this data and turns it into visual representations of the activity levels within different areas of the brain. PET has average spatial resolution - active areas within the brain are able to be detected within 5-10mm. PET however has lots of limitations. One is that it's temporal resolution is ver poor. It can't detect the quick alterations in brain activity that is

see inside the body. Various distinctive imaging exams can be utilized to give this view such as X-ray, magnetic resonance imaging, ultrasound, computed tomography scan, and positron emission tomography scan. Moreover, without analysis, there is no treatment, so radiology is basic to an analysis of numerous illnesses, especially cancer. Early analysis spares lives (4). There is a type of rays that help to treat, it called radiation therapy. Radiation therapy utilizes high-vitality beams to treat…

Positron Emission Tomography and Radioactive Tracers Essay

Radioactive tracers Introduction Transportation, whether in plants or animals is the key to the efficient assimilation of the nutrients that the organisms synthesise, get from their environment or digest. The study of these processes helps us in many ways. The study of transport mechanisms in plants helps us to understand the uptake of the various types of substances and their passage through the plants. This has helped a great deal in developing fungicides, pesticides, growth regulators…

Essay on Radiology: X-ray and Body

Humanity, constantly learning, growing, and facing more challenges each second of the day. Whether the challenges are mental or purely physical, we have found more efficient, safer, and easier ways of doing the tasks we may face. From moving cargo to sending information via the Internet. Probably the greatest accomplishments we have made, are in the studies of medicine/treatment; to be specific, the study of radiology. Radiology is the process of working and viewing inside the human body…

Epilepsy: Central Nervous System

1. Name of condition Epilepsy is a condition of recurrent, unprovoked seizures which are paroxysmal transient disturbance of nervous system function that results from the abnormal electric activity of the brain. • Can be categorized into two main types or groups, depending on the site of the seizures: partial (focal) seizures and generalized seizures. 2. Etiology: causative agent There are many plausible causes of epilepsy. These causes include genetic, acquired and provoking factors. Epilepsy…

POSITRON EMISSION TOMOGRAPHY: A radioactive substance (usually an isotope incorporated into a sugar like molecule) that releases radioactive particles called positrons is injected and travels to specialized areas of the body. PULMONARY PERFUSION SCAN: Radioactive particles are injected intravenously and travel rapidly to areas of the…

Not only does play influence thinking and analysis, but it also influences adolescent human brain development. Recent neurological research strongly supports the link between play and cognitive development (Frost, 1998) and that children who have had no experience in play suffer cognitive development…

The patient then lies down on an exam table and is passed through the PET scan, which looks like a large donut. Rings in the machine detect the emission of energy from the radioactive substance in the body. X-ray What is a X-ray scan An X-ray, a type of high-energy electromagnetic radiation, is often used for medical imaging. X-ray technology may be used to examine many parts of the body.
