X-ray computed tomography

class, I had never experienced getting an x-ray or any other type of radiation modality growing up. I became interested in the science and anatomy aspect of radiation sciences and also was amazed at how a machine could produce images of bones, babies in the womb, arteries, etc. I traveled to Mercy Hospital in Iowa City for my first job shadowing experience where I observed several barium studies of the upper gastrointestinal tract. I also observed x-ray, CT, and MRI. Afterwards…

the structure and in vitro brain functions (in certain nerve cells in the brain tissue culture), with the introduction of non-invasive neuroimaging techniques (X-ray computed tomography - CT, magnetic resonance imaging - MRI, magnetic resonance spectroscopy, and functional MRI - fMRI, SPECT - OFET or the SPECT, positron emission tomography - PET) in order to clearly see and quantify many parameters lifetime structure, local blood flow and brain metabolism in health and disease, as well as…

with you on the inside. A Radiologist is a medical doctor (MD) or doctors of osteopathic medicine (DOs) who specialize in using medical imaging techniques that help diagnose and treat diseases and injuries. The medical imaging that they use would be x-rays, CTs,…

Computed tomography (CT) is a computerized method that uses a computer to process the data collected from the passage of x-ray beams through the region of interest. The multislice CT (MSCT) means CT that the system equipped with multiple rows of CT detectors to create images of multiple sections. The data obtained from the patient will be transformed into “cuts” or cross-sectional slices of the human body (Romans, 2011). In early 1970, they use a single slice CT scan that contributes too many…

Imaging is a specialty of medicine that uses nonionizing and ionizing radiation for diagnosing and intervention of disease. Diagnostic Imaging uses imaging techniques, such as magnetic resonance imaging (MRI), X-ray radiography, computed tomography (CT), nuclear medicine, positron emission tomography (PET) and ultrasound to image inside the human anatomy in to diagnose abnormalities and disease. The meaning of imaging in radiology is to create a picture of the inside configuration of a thick…

My ideal chosen career for the future is to be a radiologic technologist. According to the occupational outlook handbook, a radiologic technologist is an individual who executes diagnostic imaging examinations. In 2012 there were around 199,200 individuals working as radiologic technologists. Typically, radiologic technologists work in health care facilities, roughly 55% of them being employed by general medical and surgical hospitals that are state hospitals, local hospitals, or private…

CT scans is essentially a more in –depth X-ray that uses computer technology to gather a more detailed image that is cross-sectional. A CT scan offers the physician insight as to size, shape and longitudinal location of structures that lie deep inside the body such as organs, tissues and tumors…

experiences which affect their lives in either positive or negative ways. To be more specific, the field of photography is a field which has had some major technological advancements with imaging, resulting in the discovery of radiographs, computed tomography and magnetic resonance imaging. The chain reaction of advancements from photography to medicine has helped the world in increasing life expectancies, discoveries of deadly diseases, and curing health conditions. As things evolve, society…

people being over exposed to radiation, when it can be so easily prevented? Unborn children are having full “babygram”, which is an x-ray of an infant’s entire body, and leaving sensitive organs exposed with no shielding (Bogdanich & Rebelo, 2011). Many other procedures that are commonly done are computed tomography, magnetic resonance imaging, and positron emission tomography. Radiologic technicians are trained and certified to perform such procedures on delicate persons, so information…

MRI and CT scans are important in the medical field because they distinguish between healthy and unhealthy tissue in the human body. Doctors use these tests so they can see through a picture what is wrong with a patient. Even though both tests are important and helpful, they have their pros and cons. Many people may think that MRI’s and CT’s are similar because they both provide images on the inside of the human body. These two machines work differently and are used differently. MRI scans are…
