What are radiopharmaceuticals and their effect in medicine? Radiopharmaceuticals are pharmaceutical compounds comprising of radioisotopes and organic carrier molecules, they’re derived to assist diagnostic and therapeutic procedures in the medical industry. The composition of radioactive pharmaceuticals is dependent on the intended physiological purpose concerning a specific organ. The radioisotope, within the radiopharmaceutical, emits gamma radiation through its decay (to obtain stability) whilst

Introduction: Iodine-131 is a synthetic radioisotope of the element Iodine and is commonly formed in nuclear reactors. Other isotopes of Iodine include iodine-129, iodine-124 and 123 which is commonly used in medical imaging and the less common iodine-125 which can be used to treat cancerous tissue.1 As Iodine-131 is a radioisotope it undergoes radioactive decay in order to stabilise itself. Iodine-131 undergoes a type of radioactive decay called beta negative decay (-), where a neutron in the

roll when your dealing with emotions, but its purpose is so much more than anyone realizes when it comes to our body. It helps regulate our body and its systems to keep us moving and healthy in our day-to-day lives. So when having to deal with a nuclear cardiac study to test its function and anatomy, it is something that can be just as complex when providing a proper data for diagnosis for your physician. You want to ask yourself three vital questions: What is the best protocol, How do we prove to

There are three different types of radiation, alpha radiation, beta radiation and gamma radiation all which can, in general terms can benefit human by usage in medical procedures to detect errors in the human body. However these radiation can also be the cause of defects and errors in the human anatomy. Alpha particles - Alpha particles are helium nuclei that contains two protons and two neutrons. Alpha particles are positively charged. They can’t travel easily through thin materials and can be

Introduction Positron emission tomography is used for research and medical diagnosis of soft tissue in humans and animals. It uses radioactive drug tracers that are swallowed, injected, or inhaled into the body, to produce radioactive emissions that are then detected with a computer tomographer (Mayo Clinic 2013). This computer tomographer creates an image much like a camera makes an image on film, when exposed to light (Denniston 2014). The scans are then used to produce three dimensional images

Tatsuya Tsunemi Radioactive Isotopes What is a radioisotope? An isotope means that same chemical elements but they are able to gain and lose some neutrons and it means they have different mass numbers but that are all still the same element because they all have same atomic number and same amount of electrons. Some of them are stable and unstable and unstable ones start radioactive decay by time because of some reasons which includes they cannot keep staying together, they have too many or too

Myocardial Perfusion Imaging is also known as (MPI). It is an imaging modality used in nuclear medicine to demonstrate 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

1. * Ultrasound techniques are used to detect structure inside the body. A gel is used when a 1MHz transducer is placed on the skin to avoid acoustic mismatch at the skin-transducer interface. (a) Define acoustic mismatch (in this particular case). Acoustic mismatch, by definition, is the discrepancy between the acoustic impedances of two or more mediums (MacLennan, 2006). This occurs when a propagated soundwave, passing through one medium, travels into another medium of unequal impedance. In the

“spacecrafts, pacemakers, underwater systems, electric automobiles, and remote monitoring systems” (source 6), the atomic battery has existed for over a century and is growing to benefit our world. The atomic battery generates electricity from a nuclear reaction, utilizing the radioactive decay of specific elements. The atomic battery is certainly not meant for households or as a source of common battery use, but rather powerful equipment needing to run for long, extended periods. Atomic batteries
