Nuclear Chemistry By: Giovanni Nunez Daniel Nemariam Andrew Wang Njweng Yangni Zainil Kadiwal Daniel Nemariam Introduction Nuclear Medicine is the used of using radiation to fight and cure diseases. Nuclear medicine has made many advancement in nuclear energy. The main one is the ability to fight cancer really well. Giovanni Nuñez Nuclear Medicine Nuclear Medicine is the branch of medicine that uses nuclear properties for diagnosis and therapy. In other words take images of the body and treat disease. Giovanni Nuñez Timeline of events that lead to modern Nuclear Medicine Henri Becquerel (1852-1908) French Physicist discovered radioactivity in 1896\ Wilhelm Röentgen (1845-1923) German physicist who discovered X-rays in 1895. Pierre Curie (1859-1906)French physicist who, along with his wife Marie Sklodowska Curie, isolated polonium and radium in 1898. Giovanni Nuñez Time line continued Revigorator After its discovery by Marie and Pierre Curie in 1898, radium was considered a "cureall" until the early 1920s Marshall Brucer (1913-1994) A "Father of Nuclear Medicine" and first president of the Society of Nuclear Medicine Hal Anger American inventor of the scintillation scanning camera in 1958 Giovanni Nuñez History of the X-Ray In 1895, Wilhelm Konrad Roentgen a professor of Physics, He discovered mysterious ray when he put a vacuum tube near a photographic plate. Theses ray went through skin and muscle but were absorb by bone. The rays would bounce off a metallic target and the rays could be focus on photographic film. Giovanni Nuñez Future of Nuclear Medicine The Future of Nuclear Medicine In the near future development of radiopharmaceuticals, or nuclear medicine, will be used to detect cancer and create genetically engineered antibodies to fight of cancer. Daniel Nemariam History of Nuclear Medicine The beginning of Nuclear Medicine in 1902 by Pierre Curie and his wife Marie Sklodowska Curie. They discovered a substance that gave off more radio activity than others. This substance was made of 2 elements radium and polonium. Daniel Nemariam History When the curies discovered radium it was said that is was the beginning of the nuclear age Irene Joliot-Curie the daughter of Pierre and Marie create artificial radiation Daniel Nemariam History Back then the curie didn’t now the effect of too much radiation. Too much handling of radiation caused scaring on Marie curie hands. The effect of radiation brought the cancerous disease leukemia and Maria and Irene died before the age of 70 http://gtm-media.discoveryeducation.com/videos/11876/chp898113_700k.asf Andrew Wang Radiology Is the field of diagnosing and treating disease and injury by using medical imaging techniques. Some of the equipment used are x-rays, computed topography, magnetic Andrew Wang Radiology a person who studies this field is called a radiologist you must first go though 4 years of medical education in radiation safety/protection, radiation effects on the human body, appropriate performance and interpretation of duality radiological medical imaging examinations 1 to 2 years of specialized training in a particular subspecialty of radiology is beneficial What is radiation therapy? What is radiation therapy? treats cancer kill cancer cells , shrink tumors 2 types *External beam radiationregular X-rays Njweng Yangni Internal radiation or Brach therapyradioactive substances placed within the tumor beside (carcinogens) to kill the cancer cells *patients usually stay in the hospital for about a day * permanent or temporary Andrew Wang Radiation therapy Advantage Kills cancer cells The amount of radiation that a patient gets is determine by the doctor. Disadvantage Hair loss Rash Vomiting Nausea diarrhea what is chemotherapy? -use of drugs to kill cancer cells Njweng Yangni How does chemotherapy work? the drugs interfere with the cancer cells ability to divide What is the difference between radiation and chemo? chemo: chemical agents;medical oncologist -radiation:; radiation oncologist Andrew Wang Chemicals Some of the Chemical used are alkalizing/cross-linking agents, antibiotics, ant metabolites/inhibitors, hormones, cytokines How do X-rays work? Goes through nonmetallic materials Smash of concentrated beam of electrons and a metal plate. The result: x-rays X-rays secondary plate to prevent the scattering of electrons- shows parts that contain metals ,growths, bone and mineral deposits-foreign objects contrast agents shows veins and arteries Njweng Yangni MRI Zainil Kadiwal MRI stands for Magnetic resonance imaging MR imaging uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. CAT Zainil Kadiwal Stands for Computed Tomography CT imaging uses special x-ray equipment to produce multiple images or pictures of the inside of the body The CT scanner is typically a large machine with a hole, or tunnel, in the center A major advantage of CT is that it is able to image bone, soft tissue and blood vessels all at the same time. PET Zainil Kadiwal Stands for Positron Emission Tomography PET scans are used most often to detect cancer and to examine the effects of cancer therapy. The radioactive may expose radiation to the fetus in patients who are pregnant. Difference between PET and CAT scan Zainil Kadiwal CT scans of internal organs, bone, soft tissue and blood vessels provide greater clarity than conventional x-ray exams. PET scans are used most often to detect cancer Daniel Nemariam Summary Nuclear medicine has made many advances in curing or fighting diseases like cancer. If technology in the medical field keeps grow soon they will be able to find a cure for cancer.
