which are quickly vacated from the body. 152Tb with a half like of 17.5 hours emits positrons perfect for postitron emission tomography imaging. 155Tb emits gamma rays and has a half life of 5.32 days with relatively low energies of 86.55 and 105.3 keV respectively, it is being tested for diagnostic purposes for positron emission tomography and single-photon emission computed tomography cameras. 161Tb produces beta minus particles and is being tested for therapeutic purposes while showing great promise

the heart muscle functions; a low dose of radioactive agent is used for this study called a radiotracer. There are two different types of techniques used for myocardial perfusion imaging. The first is, single photon emission computed tomography (SPECT) and the second, positron emission tomography (PET). Myocardial perfusion imaging is commonly done for patients whose experience some type of chest discomfort, a recent myocardial infarction, or it may be used to access the blood flow to the myocardium

Other uses of nuclear power included Military: The US Navy has all submarines and aircraft carriers moving by nuclear propulsion this lowers petroleum oil use (ships and aircrafts) by 15%. The US Military has several Nuclear Weapons Types: Warheads:The term warhead refers to the explosive and/or toxic material that is delivered by a missile, rocket, or torpedo;Bombs, Atomic Demolition Munition(ADM) ,Artillery Shell,ASW (anti-submarine warfare),ASW warhead,ASW warhead / Bomb, Torpedoes,Inter-continental

This paper attempts to analyze different imaging modalities as they pertain to the targeting and tracking of stem cells within the body. Nuclear medicine modalities, positron emission tomography (PET) and single photon emission computed tomography (SPECT), are utilized to image the physiological changes within the body and the migration of stem cells. Magnetic resonance imaging (MRI) can be used to target and track stem cells while maintaining their viability. Although these modalities are effective

atomic number but different in atomic mass.because of their characteristic nature of producing radiation and their energies. Isotopes are used in various areas like industries, agriculture, medical field and research centers. They are decayed by emission of energy in the form of alpha, beta (electron) beta plus (positron) and gamma rays. (1) Types of radiation Alpha particles cannot be used for measurement from outside the body because they are such low penetrating power. A sheet of paper stops alpha

Positron Emission Tomography Positron Emission Tomography is a scanning technique that allows us to measure in detail the functioning of distinct areas of the human brain while the patient is comfortable, conscious and alert. PET represents a type of functional imaging, unlike X-rays or CT scans, which show only structural details within the brain. The differences between these types of imaging don’t end there. In both X-rays and CT scans, a form of radiation is emitted and travels through the

The Impact of DaTscan on the Diagnosis and Management of Movement Disorders: A Retrospective Study. New and evolving diagnostic tests are always exciting. Especially if these tests could possibly lead us to a cure for those diseases that currently have only treatment, but no cures. Parkinson 's is a progressively degenerative disease, which affects millions of people every year. Patients suffering from Parkinson 's incur high costs from drug therapy, fall-related injuries, and hospitalizations

Through the decades, researchers have tried to solve the mystery of the enigmatic prefrontal cortex. Along with the famous case of Phineas Gage (Harlow,1848), many studies have attempted to answer the burning question of either or not lesions to the prefrontal cortex lead to an antisocial behavior. The PFC, which is found in the frontal lobe and has an executive function, helps us have an appropriate response to social situations. Why is it important to study this matter? Because we are social creatures

2.3 β-particle emission radionuclides Β-particles are high energy electrons which are ejected from the nucleus with a range of energies up to a maximal value.12 β-emitters are heavily researched and are a widely accessible form of radionuclide therapy. The LET of β-emitting particles is high enough to kill cancerous cells, but is considered low compared to α-emitters which have a lot more particles in the higher energy levels. Β-particle emitters deposit their energy over a much larger range (1mm
