“YOU’RE GLOWING! Nuclear Medicine Application” At some point in our lives a doctor will decide they need a better idea of what is going on inside your body. They will send you to the medical imaging department for an x-ray, CAT (Computerized Axial Tomography) scan or an MRI (Magnetic Resonance Imaging) scan. Those big words might be scary but thanks to medical radiation, we can have a better diagnosis. X-rays create a grayscale image of whatever they pass through. Denser tissue creates a whiter image on the x-ray. (Pettigrew) Whatever part needs to be examined will be positioned over film or detector linked to a computer. (McCarthy) X-rays can be used as radiography, mammography, CT (computed tomography), fluoroscopy and lastly, radiation therapy in cancer treatment. (Pettigrew) In some cases a contrast agent may be used to provide clearer images of organs or tissue. X-rays provide a noninvasive painless procedure to aid a doctor's diagnosis. (Division of Human Resources Management) They can provide an update on therapy, support medical and surgical treatment and guide medical staff as they insert catheters, stents, or other devices in the body, also treat tumors, remove blood clots or blockages (Division of Human Resources Management) Since x-rays use ionizing radiation to generate images of the body there is some risk involved with their use. “Ionizing radiation is a form of radiation that has enough energy to potentially cause damage to DNA.” (Pettigrew) Risks from exposure to ionizing radiation includes a small increase of possibility that the person will develop cancer later in life or tissue effects such as cataracts, skin reddening and hair loss, which occurs at a high level of radiation exposure and in this case, it’s rare.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
