Nuclear Medicine: Nt1310 Unit 9 Final Paper

Positron emission tomography or pet, it is an advanced tomographic functional imaging modality. This technique depends on detecting gamma ray produced by radio tracer like 18 F "FDG" flouro deoxyglucose through pair production resulting in a pair of gamma-ray each with 511 Kev energy an 180° "add picture of annihilation event ".

Participation in the MD Anderson 1st Year Medical Student Program would provide a research based experience that would catalyze my goals for the future. Investigations with results that could prove practical towards my patients at the bedside are of great interest to me. This has sparked my attention towards translational medicine as a promising area of investigation. I believe the field of radiomics in particular has tremendous potential for clinical applications in direct patient care, especially in the field of oncology. Radiomics lies at the juncture of what I believe to be extremely exciting science in the coming future of personalized medicine. This is what prompted me to approach Dr. Rivka Colen (desired mentor), of the Department of Diagnostic Radiology, to conduct research in her lab. An interplay between research and clinical treatment such as the way Dr. Colen implements will be one of the grounds that I intend to structure my own practice around. The MD Anderson 1st Year Medical Student Program would help me achieve the first steps towards conducting research in my career as a physician-scientist. After this research experience, I hope to have a better understanding of my place in the world of

The objectives of the specific department are to have an open relationship amongst technologists, nurses, and radiologists as well as to have knowledge of the individual procedures as equipment to ensure proper patient care and safety. This ensures that patients are not only safe physically but the technologist know the effects of radiation and know the proper steps to minimize those and the nurses also know the proper protocols to ensure adequate comfort but to also have the knowledge and skills to handle an emergency situation.

Radiation exposure has been proven to be detrimental to both the patients’ health and the technicians. If exposed to too much radiation, it can eventually cause cancer. Radiation deals more with the patient since they are the ones being tested to see what is wrong and where the pain is coming from. The technicians are suppose to take all safety precautions to protect both themselves and the patients’.

Dental radiographs are important tools in the diagnosis of oral diseases. It helps the dentist to employ appropriate treatment regimen for patient’s dental conditions, and plays a continual important role in dental practice. Radiation dosage from such dental radiographs are low and are thought to present minimal risk (Enabulele & Igbinedion, 2013)

If you think back to grade school, then you remember them always asking what you want to be when you get older. Most children will tell you a firefighter, astronaut, pilot, princess, or something else that they say just because they are young. The time has come for puberty, an increase in maturity levels, and to narrow down what career field to choose.Recently, I have taken a few tests to review who I am and what field will work best for me. A reality check hit me harder than a bug getting hit by a bus. The tests predicted that a career in health services would fancy my future. The first thing to catch my eye was the therapeutic services tab. Once I actually did some digging through all the various careers I finally found radiology therapy.

Many people may worry that dental radiographs are not safe, because we all know that radiation exposure can cause cancer, which is the mutation of cells. While cancer caused by radiation is a very valid concern, the amount of radiation a patient would be exposed to during a dental radiograph would usually be too low to pose a health risk depending on the tissues that are to be examined and the size of patient. Subsequently, many techniques are used in the dental office to make sure that patients and employees are protected as much as possible from the risk of radiation exposure.

This website gives information about Napalm bomb. In this website historical information is given as well as its production and its effect on Americans. As anyone can see on the left hand side that it is directly linked to some social websites for direct sharing therefore it is very helpful. Another thing is anyone can directly print a topic from this website. It gives extra information as well. As you can see the options on the dashboard which are facts, events, question and media, these option provide information on the given topic. In “media” option there are videos as well which can be helpful for anyone.

Part 2: Describe the methodology and critically evaluate the results for TWO specified quality assurance (QA) tests you have undertaken on your MRI scanner.

MRI is considered a safe way for screening because it does not use radiation unlike other methods of screening. Moreover, there are few risks that results from the MRI scan for those who have implants that contains metals because the magnet in the MRI can cause problems such as the implanted pins or screws to move in the body (Kim, S., 2015).

Radiographers should always apply the As Low As Reasonably Achievable or ALARA principle when undertaking a medical X-ray exposure. There are evidences that demonstrate that diagnostic X-ray procedures have the ability to induce cancer and genetic effects, although the risk is known to be very low. Hence, it is the responsibility of radiographers to always ensure to minimise this risk by minimising the radiation dose to the patient, ultimately producing the best diagnostic image and delivering the highest quality of care.

A CT scan, CT standing for computed tomography, uses X-Rays from many different angels to make a detailed picture of the structures inside the body. It allows doctors to see what is happening inside the body without having to cut somebody open. A CT scan is taken in a donut shaped ring and a bed, the bed gets rolled into the scanner. An MRI, standing for magnetic resonance imagining, use strong magnetic fields to make photos of the organs in a person's body without cutting the body open. An MRI machine does not use X-rays to make photos. MRI scans take much longer time t produce a detailed photo and is a lot more noisy than CT scans. Another difference between MRI scans and CT scans is that CT scans are suitable for bone injuries, lung and chest imagining and cancer detection. While MRI scans are suitable for soft tissue evaluation, e.g., ligament and tendon injury, spinal cord injury, brain tumors, etc.

A calendar quarter means any 3-month period determined as follows: The first period of any year may begin on any date in January: provided, that the second, third, and fourth periods accordingly begin on the same date in April, July, and October, respectively, and that the fourth period extends into January of the succeeding year (29 CFR 1910 OSHA General Industry Regulations, 2014). Rem means a measure of the dose of any ionizing radiation to body tissue in terms of its estimated biological effect relative to a dose of 1 roentgen (r) of X-rays (1 millirem (mrem)=0.001 rem). The relation of the rem to other dose units depends upon the biological effect under consideration and upon the conditions for irradiation (29 CFR 1910 OSHA General Industry

potentially overlapping parts such as WM, GM and CSF.MRI is one of the common ways to visualize brain structure. Automatic segmentation of MR images is very useful for research and clinical study of much neurological pathology. The MRI scan is more reliable than CT scan for diagnosis because it does not affect the human body as it does not use any kind of radiation. MRI shares a common advantage with CT of high spatial resolution images but without ionizing radiation exposure. It possesses good contrast resolution for different tissues.

This test can recognise changes done to internal organs faster than a normal x-rays. It is known as a more improved measure but it works just like an x-ray. The procedure of this scan starts when the doctor gives a patient a special injection of a substance that can help find out whether there are chances or damages done to organs such the spleen and others. It also uses a special computing software which allows the doctor to find the perfect image of the damaged organ and where exact is the damage done on that object.
