    Advanced Nuclear Medicine Through Research Advanced Nuclear Medicine Through Research Presentation Transcript

    • Advancing Nuclear Medicine through Research
      Jennifer McKenzie, CNMT
      NUCM 480
    • What is Nuclear Medicine?
      Nuclear medicine specialists use safe, painless, and cost-effective techniques to image the body and treat disease.
      Nuclear medicine imaging is unique, because it provides doctors with information about both structure and function.
      It is a way to gather medical information that would otherwise be unavailable, require surgery, or necessitate more expensive diagnostic tests.
      Nuclear Medicine imaging procedures often identify abnormalities very early in the progress of a disease long before many medical problems are apparent with other diagnostic tests.
    • Who is it for?
      Today, nuclear medicine offers procedures that are essential in many medical specialties, from pediatrics to cardiology to psychiatry.
      New and innovative nuclear medicine treatments that target and pinpoint molecular levels within the body are revolutionizing our understanding of and approach to a range of diseases and conditions.
    • Patient Care Practices
      Nuclear medicine is divided into two major areas: diagnostics and therapeutics.
      The diagnostic side is mature, while the therapeutic side of nuclear medicine is in its infancy.
      Over 100 diagnostic radiopharmaceutical products are available.
      The largest number of these radiopharmaceuticals have applications in cardiology, followed by oncology and neurology.
      A few radiopharmaceuticals have applications in other areas, such as infection imaging and nephrology.
      We use evidence based medicine and patient care practice information to help shape the future of our field as we continually strive to provide patients with the best health care possible.
    • Research in
      Nuclear Medicine
      There is no doubt that Nuclear Medicine is a field that witnesses impressive technological progress and changes
      Clinical research is critical to this progress
      Some of the effects of both current and past research in Nuclear Medicine include:
      Improved diagnostic testing
      Better imaging drugs and radiopharmaceuticals
      Better treatment therapies
      Safer patient care practices
    • Development of Imaging Equipment
      Over the years, nuclear medicine has seen tremendous advances in the way we diagnose disease within the body
      Exploratory surgery used to be the way doctors investigated health problems
      Since the 1950s, nuclear technologies have offered an array of different techniques without the pain of surgery
      Scanners have evolved from single planar to SPECT to PET and now to SPECT/CT and PET/CT
      PET/MRI and PEM (positron emission mammography) are two others that will soon become more readily available
    • Timeline of Imaging Equipment
      1951 – a scintillation detector to “scan” the distribution of radioiodine within the thyroid gland was invented
      1954 – photorecording system for radionuclide scanning was invented
      1958 – scintillation camera was invented that made it possible to conduct dynamic studies
      1959 – first rectilinear scanner
      1962 – emission reconstruction tomography was introduced
      Later to be known as SPECT and PET
      1976 – the first general purpose SPECT camera was developed
      1983 – first successful PET scan was performed
      2008 – the first hybrid PET/MRI system for humans was installed
      Without research, none of this would be possible or available today!

    • Diagnostic
      Radiopharmaceuticals
      Molecular imaging at a cellular level is currently the main focus in the research of diagnostic radiopharmaceuticals[5]
      Another focus is working towards the development of new agents for diagnosis with 99mTc radiolabeled drugs[5]
      Shifting from conventional radiolabeling to a new method that yields a high specific activity, high stability, and site-specific radiopharmaceutical[5]
      This research allows us to provide safer diagnostic procedures with less radiation exposure to the patients.
    • Advancements with
      Radiopharmaceuticals
      The first radiopharmaceutical approved by the FDA for use was I-131 for the treatment of thyroid cancer[1]
      Since the first discovery that nuclear radiopharmaceuticals could have a diagnostic and therapeutic effect on the treatment of disease, many clinical trials have been conducted.
      It’s through those clinical trials that new drugs have been developed and utilized for the treatment and diagnosis of disease
      In the early years, diagnostics largely concentrated on bone scanning and cardiology[4]
      This has now changed with the changing market and oncology is a rapidly growing and promising area for nuclear medicine research[4]
    • Radioisotope Clinical Trials
      These are important advancements in current nuclear medicine climate
      What do Clinical Trails Accomplish?
      What results have they had?
      Clinical trials are a step in medical research conducted to allow safety (or more specifically, information about adverse drug reactions and adverse effects of other treatments) and efficacy data to be collected for health interventions
      e.g., drugs, diagnostics, devices, therapy protocols
      There is new progress made by using clinical trials almost every day, they include advancements in :
      Treatment of pain in cancer therapy
      Treatment of adverse drug reactions
      Monitoring of recovering organs or diseased organs and pathological processes
      Diagnoses
      Emergent treatment options
    • Therapeutic
      Radiopharmaceuticals Research
      Nuclear Therapy and Treatment for cancer patients are two major areas where nuclear medicine research efforts have been taken.
      Radionuclide therapy using unsealed radiotherapeudic agents is a fast emerging molecular modality
      Some of these therapies include:
      Re-188/186
      Sm-153
      Y-90
      Ho-166
      Lu-177
      Yb-175
    • Yttrium 90
      Received FDA approval in 2000 for treatment of Liver Tumors, mainly those who could not undergo surgical resection of the tumor itself.
      New Research
      A study done in 2011 by the Society of Interventional Radiology found alternative methods of radioisotope administration for Liver tumors with Yttrium 90 therapy which extended the patents lives further than the original protocol used in 2000 [7]
      Yttrium 90 research has helped reduce mortality and morbidity from Liver tumors, and give cancer patients a better quality of life.
    • Bone Pain Palliation
      Making patients comfortable while they are dealing with pain from bone metastases is a big research area for nuclear medicine
      Some new drugs that are being research and developed:
      Re-186
      Sm-153-Lu-177
      Yb-175
      What does this mean for patients?
      Advancements in treating patients with bone pain from cancer metastases help reduce suffering and morbidity in cancer patients. These advancements were not present 20 years ago in this field, and would not be present today without research progress.
    • The Forefront of Nuclear Medicine Research
      Yttrium-90 and Bone Pain Palliation Research are just two of the hundreds of research and clinical trials being conducted today.
      There is also a huge amount of research being done within the PET and oncology setting and the SNM is at the forefront of most of the research that is being conducted today.
      They provide a forum for nuclear medicine latest and most definitive scientific investigation[1]
      The Society journals, The Journal of Nuclear Medicine and The Journal of Nuclear Medicine Technologists, are the international standards in the publication of peer reviewed research in clinical and basic nuclear science.
      New research in the field is fostered by Society fellowships and through the efforts of the Education and Research Foundation.
    • Conclusion
      With the medical climate progressing in technological advances each year, and new disease processes becoming apparent, medicine must keep up.
      Medical staff needs to use the advances in research to contribute to maximal patient care.
      Nuclear Medicine is a rapidly advancing field that has undergone numerous changes over the past 30 years. It is more exciting and challenging than ever, and continues to be an area where new advances are made every day thanks to research efforts across the world.
