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 particles. Beta particles have

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

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

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

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

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

that is being investigated is the PET scan. The PET scan functions as a result of the specific atomic properties of positrons which are subatomic particles that have the opposite charge of electrons but the same mass. The PET scanner detects these positrons which are emanated by the radioactive chemicals attached to a chemical the body naturally metabolizes (Positron Emission Tomography, 2014). The PET scan is used in the fields of oncology, neurology, and cardiology to determine the flow of blood,

Carcinoma misdiagnosed as acne Basal cell carcinoma (BCC) is the most common type of skin cancer. Acne is a common skin disease characterized by blockage and/or inflammation of hair follicles and their sebaceous gland. The similarities in presentation and localization between BCC and acne may cause misdiagnosis. Researchers from Department of Plastic and Reconstructive Surgery, Denmark reported a case of 53‐year‐old Caucasian male. He was presented with a subcutaneous swelling in his right axilla

techniques, such as x-rays, computed tomography (CT) or (CAT), magnetic resonance imaging (MRI), nuclear medicine, positron emission tomography (PET) and ultrasound. Computed tomography, commonly known as CT or CAT scan, is a painless, non-invasive diagnostic tool that uses a specialized form of X-ray coupled with computer technology to produce cross-sectional images (slices) of soft tissue, organs, bone and blood vessels in any area of your body. Positron emission tomography (PET) is a noninvasive, diagnostic
