Essays on Nuclear Medicine

I am currently seeking to change my major from Pharmacy to Nuclear medicine technology. One day I realised that the major I chose was not exactly what I wanted to do in my life, because it would not be able to satisfy my ambitions and plans in my life. What is more, I clearly understand that it is easier and better for me to change it now than to spend more time for what I do not want to do. As soon as my major now will define my profession in the future, I have realized that I want ...

Introduction

Radiation detectors are widely applied in numerous fields for early detection and mitigation of radiation effects within premises. The advantages associated with the application of radiation detectors are tremendous not only in the medical field but also other professional fields where radiation detectors are employed. Owing to these positive benefits of radiation detectors, their application for various functions across different fields has grown at an alarming rate ever since their inception. Radiation detectors come in numerous types and shapes (Owens and Peacock, 2004). Nuclear medicine is notorious for the application of radiation detectors as compared to other professional fields. ...

Single-photon emission computed tomography (SPECT scintigraphy) utilizes nuclear medicine along with gamma rays to get three-dimensional images (NLM, n.d.) of an internal part of the body such as heart with an objective of diagnosing a problem.

SPECT

In SPECT, a gamma-emitting radioisotope is administered into the bloodstream of a patient with the help of injection (Boyd, 2014; Hademenos, 1998). The radioisotope is, usually, a simple soluble ion as, for example, isotope of gallium(III) (Sharma, Prior, Belinsky, Kruh, & Piwnica-Worms, 2005; Wadas, Wong, Weisman, & Anderson, 2010). Most often, a marker radioisotope is also bound to a particular ligand ...

Abstract

This research project is focused on investigation and simulation of radiation detector failures. This technical device are used in Nuclear Medicine where the problem associated with detection canceled to major damage to staff and patients. Investigation focused on the determination of failure cause for detectors and other equipment like monitors and so on and assessment of post-detection actions Simulation focused on the determination of a mathematical equation of detector failure prediction and assessment of suitability of the detectors (optional) The first phase will result in the list of major failure causes referred to detectors and the associated equipment. The ...

Introduction

The only proven strategy to fight any form of cancer is early detection based on evidence and researchers. Based on current evidence, low-dose computed tomography (CT) is highly recommended for patients with high risk for lung cancer. Many researchers state the potential advantages of CT screening in such patients over conventional screening methods. The American Cancer Society and American Lung Cancer Association, early detection and CT screening is one of the best and only proven methods to fight lung cancer across all age groups. In the US, Lung Cancer is the lead cause of cancer-associated death with an alarming ...

Positron Emission Tomography (PET), in recent years, has experienced accelerated development and has become an established method for medical research and clinical routine diagnostics. The development and availability of radiopharmaceuticals specific for particular diseases is one of the major driving forces for the expansion of PET (Fani et al, 2008, pg. 1). Currently, DOTA peptides such as DOTATOC, DOTATATE and DOTA-NOC among others are being promoted for routine clinical use in nuclear medicine. The increase in the knowledge of purification and the concentration of the eluate and the complex ligand chemistry has led to the (68) Ga-labeled pharmaceuticals with a ...

Question 1: Rationale and Comparative Advantages

The technology behind PET-MRI presents a major stride in terms of nuclear medicine. Since the inception of nuclear medicine as a discipline, the overall medical domain has received a huge boost in terms of precision in diagnosis and treatment (Boss at al., 2010). However, the PET-MRI is the most recent advancement in this field and is promising to impact on medicine in a very positive manner. The contemporary world is faced by a myriad of intricate health conditions that require an equally sophisticated approach. It is the technologies such as the PER-MRI that hold the key to the 21st century medicine. PET-MRI is a hybrid ...

Introduction

Physics refers to the branch of science that primarily deals with nature and properties of matter and energy. Its key components are heat, mechanics, light, sound, magnetism, structural orientation of atoms, and electricity. Any technology we use in our daily lives has a relation to physics. Physics is more of the backbone for most daily life activities. Examples include electric light in our homes, cell phones, , computer, CD player plasma TV set, wrist watches, radio, and working of our vehicles. Physics plays a key role in the production of energy. These various energies are then transformed into electricity for eventual ...

The treatment, diagnosis and radioactivity for imaging can be conducted using nuclear medicine that is a particular area of contemporary medicine. The small quantities of the radioactive substance are injected into the body by means of a number of techniques of imaging. The injected substance can then be traced using some sensing device specifically for the kind of radiation released from the substance. In cases where the diseased tissues go beyond normal surgical methods, the radiation is applied to get rid of dead tissues (Christian & Waterstram, 2013). There are different kinds of radiation used in the field of medicine. Most ...

Introduction about the Radioisotopes

In this paper, a trainee is going to learn about the operation and handling of radioisotopes. Nuclear medicine is a branch of medicine using the radiation to analyze the function of the organs. This information is used by the physicians to have an accurate diagnosis. The radioisotopes are used to determine the affected organs in our body. The problems, like, thyroid, organs, bones, and many other organs can be easily imaged using this device. Over 10, 000 hospitals are currently using the radioisotopes in the medical field. The radioisotopes are the common isotopes used for diagnosis in technetium – 99. In the ...

Nuclear medicine is a technique used in diagnosing and treating diseases using small amounts of radioactive materials. The technique utilizes the radioactive decay process and relies on radionuclides which are described as radioactive isotopes that can be traced by a gamma camera connected to a computerized system. The amounts of radionuclides introduced into the body is carefully selected to ensure that it only offers the accurate diagnosis and treatment results without exposing the patient to levels of radioactive material that would be harmful to them (Nuclear Medicine). These radionuclides are introduced in the body through several methods. It can be done through ...

Nuclear medicine is the use of radioactive isotopes to diagnose and treat patients. It is considered a functional measurement method, as the imaging is based on cellular function and physiology, rather than structure, like an X-ray (Prvulovich & Bomanji, 1998). The kind of radiation that is measured in nuclear medicine is gamma rays. Patients are prepared for a nuclear medicine procedure by having an amount of tracer isotope administered that is just enough to obtain the sought for information before its decay. The World Nuclear Association reports that in the United States each year there are about 18 million nuclear medicine procedures ...

I. Natural Radioactivity

Radioactivity is a natural phenomenon occurring in isotopes of elements with atomic numbers 20 and higher. This takes place in isotopes of elements with unstable atomic nuclei. Radiation-emitting isotopes are called radioisotopes. When an atom has an unstable nucleus, the number of protons and neutrons are not balanced and there are either too many protons or there are too few of it. This imbalance causes the nuclei to spontaneously decompose to form a more stable nucleus. During this process, energy or particles are released and this is known as radiation. There are three types of radiation. These are either in ...
