what radiographer need to know covid-19
0 likes100 views
Medical imaging plays an important role in diagnosing COVID-19 patients, especially those most severely affected. Chest radiographs should be the first-line imaging tool, while chest CT should only be used for critically ill patients or when chest radiographs are inconclusive. As radiographers work on the frontlines, they need to be aware of COVID-19 risks and engage in strategies to reduce risks like using personal protective equipment. Radiography practices must adjust to recommendations like limiting medical imaging to critically ill patients and adopting protocols for low dose CT and infection control to safely diagnose COVID-19 while reducing radiation exposure and infection risks for radiology departments.

This document summarizes evidence for medications that can be used to lower the risk of colorectal cancer (CRC) through chemoprevention. It finds strong evidence that aspirin can prevent colorectal neoplasia for individuals at cardiovascular risk who are not at high risk of bleeding. While observational studies support metformin, more robust trial data is still needed. Non-aspirin NSAIDs, calcium, vitamin D, folic acid, and statins either have safety issues or lack proven efficacy for CRC chemoprevention. Future studies should evaluate combinations of medications to uncover potential synergistic effects.Woundontology Consortium

Health, human development and overall wellbeing are highly intertwined and the coronavirus disease (COVID-19) makes this most implicit especially for the low and middle-income countries. More than ever, there is a need to develop a functional health system that fosters social economic political development in developing countries such as Kenya. This paper makes a case for expanded social-psychological interventions patterns for the management of COVID-19. The aim is to develop a model for health-care investment amidst COVID-19 and provide the operations and structure of strategies leading to successful management of the epidemic. This involves a comprehensive social-psychological approach in the health-care system that fosters improved health and wellbeing through a more wide-ranging understanding to enhance the involvement of the individual, family, community and nations. The framework examines the various intervention strategies in COVID-19 as well as the underlying engrossment in the strategies with an aim of successfully involving the individual in a systematic social psychological understanding of COVID-19. The model provided is relevant to health-care strategies in post-COVID-19.Supporting rare cancer patients' journey through national cancer control plans

油
The document discusses a parathyroid scan, which is used to localize hyperfunctioning parathyroid tissue, such as adenomas or hyperplasia. It involves injecting the patient intravenously with technetium-99m sestamibi or tetrofosmin and taking images of the neck and mediastinum at 15-20 minutes and 2 hours later. The scan is contraindicated in pregnant women or those on calcium or thyroid medication. It requires a gamma camera and involves positioning the patient supine with their neck extended for anterior and optional oblique views.Radionuclide Production - Nuclear Medicine
Radionuclide Production - Nuclear Medicine@Saudi_nmc
油
This document discusses different methods of radionuclide production, including reactors, cyclotrons, and generators. Reactors produce radionuclides like 90Sr, 99Mo, 131I, and 133Xe through fission of uranium or plutonium fuel rods. Cyclotrons bombard stable nuclei with particles like protons or alpha particles to produce radionuclides. Common generators include the 99mTc generator, which extracts 99mTc from its 99Mo parent with half lives of 67 hours and 6 hours respectively, and the 81Rb/81Kr generator, which uses a membrane to extract the short-lived 81Kr daughter from its 81Rb parent with half lives of 4.Mechanisms of radiopharmaceutical localization
Mechanisms of radiopharmaceutical localization@Saudi_nmc
油
Radiopharmaceuticals localize in tissues and organs through various mechanisms. These mechanisms include capillary blockade, phagocytosis, compartmental localization, cellular migration, active transport, chemisorption, cell sequestration, simple diffusion, receptor binding, metabolic trapping, and antigen/antibody reactions. The mechanism of localization depends on factors like the radioisotope used, its emission characteristics, and achieving a high target to non-target ratio. Understanding these mechanisms is important for producing high quality images and therapeutic results.Factors affecting the biodistribution of radiopharmaceuticals
Factors affecting the biodistribution of radiopharmaceuticals@Saudi_nmc
油
This document discusses factors that can affect the biodistribution of radiopharmaceuticals used in nuclear medicine imaging and therapy. It describes 4 main categories of factors: 1) those related to radiopharmaceutical preparation and formulation such as radiochemical impurities, 2) factors caused by administration techniques like infiltrated injections or blood clots, 3) pathophysiological and biochemical changes in the patient, and 4) medical procedures previously received by the patient like radiation therapy. Understanding these factors is important to avoid misinterpretations from scans with altered biodistribution patterns.Nuclear Medicine Formulas

Radiation Safety in the Workplace@Saudi_nmc
油
This document discusses radiation safety in the workplace. It defines radiation and different types including alpha, beta, gamma, and x-rays. About 150,000 Canadians are monitored annually for workplace radiation exposure, mostly in healthcare and nuclear power. Radiation is either ionizing, with enough energy to remove electrons from atoms, or non-ionizing. The key units discussed are activity (decays per second), half-life (time for half of atoms to decay), various dose units like gray and sievert, and limits like effective dose limits of 50 mSv per year for nuclear workers. Both acute high doses and chronic low doses are addressed, noting cancer risk increases with increased radiation exposure.Detection of Gamma Radiation
Detection of Gamma Radiation@Saudi_nmc
油
Detection of gamma radiation is used to study properties of atomic nuclei. Two common detectors are scintillation detectors and semiconductor detectors. Scintillation detectors use scintillation materials that emit visible light when struck by gamma rays, while semiconductor detectors use depletion regions in germanium crystals. Both detectors require amplification and signal processing electronics to analyze the energy deposited by gamma rays. Key measurements involve determining the energy spectrum of gamma ray sources and identifying peaks and edges that reveal information about nuclear properties and interactions.Radiation Basics
Radiation Basics@Saudi_nmc
油
Radiation comes in different forms, including ionizing radiation which can damage DNA and cause cell mutations. Ionizing radiation is emitted during radioactive decay and comes from both natural and man-made sources. Exposure to ionizing radiation, even at low doses, increases cancer risks as it can cause unpredictable damage at the cellular level. Radioactive materials also bioaccumulate up food chains, increasing exposure risks for humans. Protecting against radiation exposure and limiting contamination of the environment are therefore important public health issues.SPECT Scan
SPECT Scan@Saudi_nmc
油
A SPECT scan uses radioactive tracers and computed tomography to show blood flow to organs and tissues. A small amount of radioactive tracer is injected and detected as it passes through the body. Images are created as the tracer is detected, allowing visualization of blood flow. SPECT scans are commonly used to examine the brain, bones, and to detect tumors.Recently uploaded (20)

Creatines Untold Story and How 30-Year-Old Lessons Can Shape the Future
Creatines Untold Story and How 30-Year-Old Lessons Can Shape the FutureSteve Jennings
油
Creatine burst into the public consciousness in 1992 when an investigative reporter inside the Olympic Village in Barcelona caught wind of British athletes using a product called Ergomax C150. This led to an explosion of interest in and questions about the ingredient after high-profile British athletes won multiple gold medals.
I developed Ergomax C150, working closely with the late and great Dr. Roger Harris (1944 2024), and Prof. Erik Hultman (1925 2011), the pioneering scientists behind the landmark studies of creatine and athletic performance in the early 1990s.
Thirty years on, these are the slides I used at the Sports & Active Nutrition Summit 2025 to share the story, the lessons from that time, and how and why creatine will play a pivotal role in tomorrows high-growth active nutrition and healthspan categories.

what radiographer need to know covid-19
- 1. COVID-19 in the radiology department: What radiographers need to know Abstract Objectives The aim is to review current literature related to the diagnosis, management, and follow-up of suspected and confirmed Covid-19 cases. Key findings Medical Imaging plays an important auxiliary role in the diagnosis of Covid-19 patients, mainly those most seriously affected. Practice differs widely among different countries, mainly due to the variability of access to resources (viral testing and imaging equipment, specialised staff, protective equipment). It has been now well-documented that chest radiographs should be the first-line imaging tool and chest CT should only be reserved for critically ill patients, or when chest radiograph and clinical presentation may be inconclusive. Conclusion As radiographers work on the frontline, they should be aware of the potential risks associated with Covid-19 and engage in optimal strategies to reduce these. Their role in vetting, conducting and often reporting the imaging examinations is vital, as well as their contribution in patient safety and care. Medical Imaging should be limited to critically ill patients, and where it may have an impact on the patient management plan. Implications for practice At the time of publication, this review offers the most up-to-date recommendations for clinical practitioners in radiology departments, including radiographers. Radiography practice has to significantly adjust to these new requirements to support optimal and safe imaging practices for the diagnosis of Covid-19. The adoption of low dose CT, rigorous infection control protocols and optimal use of personal protective equipment may reduce the potential risks of radiation exposure and infection, respectively, within Radiology departments.
