Magnetic Resonance Imaging (Mri) and Computed Tomography...

Magnetic Resonance Imaging (MRI) and Computed Tomography Scan (CT) Modern medical technology allows physicians to capture detailed images of the body for diagnosing and treatment planning of various health issues. Radiologists use imaging technologies to diagnose or treat diseases. Interventional radiology is the performance of medical procedures with the guidance of imaging technologies. Acquisition of medical imaging is usually performed by a radiologic technologist and the results are interpreted by Radiologists, medical doctors that specialize in radiology. While Magnetic Resonance Imaging (MRI) and Computed Tomography Scan (CT) are useful for diagnosing and treating illnesses, each has their own health risks and benefits.†¦show more content†¦When radiological examination is recommended by a physician, the expected benefit received from the test will outweigh the potential radiation risks involved. MRI uses strong magnetic fields to align atomic nuclei (usually hydrogen protons) within body tissues, then uses a radio signal to dist urb the axis of rotation of these nuclei and observes the radio frequency signal generated as the nuclei return to their baseline states.MRI scans do not expose patients to radiation, but the high force magnetic field used can cause significant problems if proper precautions are not met. Magnetic force used can cause metallic devices or implants to malfunction or be dislocated with the body. Images can be distorted by metal and electronic objects outside the body, due to interfere with the magnetic field of the MRI unit. Over exposure and unnecessary use of these imaging modalities can cause health risk. The expected benefits received from possible early and the ability to evaluate and properly treat diseases outweighs the potential radiation risk. Discuss the risks versus benefits of radiology treatment prior to having a CT or MRI with a physician, and explore whether possible alternative imaging methods may be available to diagnose the condition. Although risks are involved with each type of imaging the most important reason they are useful for diagnosing and treating illnesses is because the detection and treatment of disease and illness can saveShow MoreRelatedImaging Research Paper729 Words   |  3 PagesOther Imaging Methods Hospitals, Doctor offices, and many more use lots of different imaging methods daily to check on different parts of your body. From doing an X-ray to check on your bones, to a CT scan to check on the brain for hemorrhages, tumors, and atrophy. To an MRI is used to image soft tissues of the body like the heart and lungs (Timberlake, Karen p. 340). In this research paper, I will talk about 2 more different imaging methods and come more in depth with X-rays, CT scans, and MRI’sRead MoreOsteoporosis1166 Words   |  5 PagesDiagnostic assessment for osteoporosis includes patient’s history, laboratory tests, and measurements of BMD (Akyol, Alayli, Diren, Cengiz, Canturk, 2008). Imaging techniques utilized in diagnosing osteoporosis are X-ray, computed tomography (CT), magnetic resonance imaging, and ultrasonography. The two main goals of diagnostic imaging of osteoporosis are identifying the presence of osteoporosis, and quantifying the bone mass using semi-quantitative or quantitative methods (Guglielmi et al., 2011)Read MoreHow has Technology Changed the field of Radiology? Essay1414 Words   |  6 Pagescomfortably in the radiology department, has been the major key to this progress†(Gerson 66). The core of radiology’s vast development consists of four diagnostic techniques: computed tomography (CT), digital subtraction angiography (DSA), ultrasonography, and magnetic resonance imaging (MRI). These methods of diagnostic imaging provide accurate information that was not seen before. Amid this information advancement, radiologists have broadened their role of diagnostician. Gerson writes, â€Å"With the adventRead MoreA Short History of MRI2254 Words   |  10 Pagesï » ¿What is MRI? Magnetic resonance imaging (MRI) is a sophisticated computerized imaging technique, which has been a clinical diagnostic tool since 1980. MRI is used to create images with extraordinary detail of the body or brain by applying nuclear magnetic resonance phenomena. The distribution of hydrogen nuclei (protons), found in cellular water, depends on the tissue type and whether or not the tissue is healthy or diseased. MRI measures and records changes in the magnetic properties of theseRead MoreEssay Magnetic Resonance Imaging927 Words   |  4 PagesMagnetic Resonance Imaging Magnetic resonance imaging has the potential of totally replacing computed tomography. If history was rewritten, and CT invented after MRI, nobody would bother to pursue CT. --Philip Drew (Mattson and Simon, 1996) WHAT IT IS Magnetic Resonance Imaging, or commonly known as MRI, is a technique used in medicine for producing images of tissues inside the body. It is an important diagnostic tool because it enables physicians to identify abnormal tissue without openingRead MoreMagnetic Resonance Imaging And The Health Field1926 Words   |  8 Pagesthe advent of magnetic resonance imaging applications in the health field forty years ago the technology has become a staple in hospitals all around the world. Magnetic resonance imaging commonly known to one of the safest forms of attaining pictures of the human anatomy. Although magnetic resonance technology is popular amongst health care providers for decades, until recently, scientists could not get the optimum image of some critical parts of the human anatomy. The magnetic resonance technologyRead MoreThe Risks And Hazards Associated With Risk Reduction And Safety Will Be Discussed2175 Words   |  9 Pagesall imaging modalities. This essay looks at Computed Tomography(CT), Magnetic Resonance Imagine (MRI) and Ultrasound (US), modalities used disease and pathology diagnosis. It will look at the scientific principles. Comparing the risks and hazards associated with each modality when examining pregnant patients. Risk reduction and safety will be discussed. Scientific Principles Computed Tomography CT is cross-sectional image acquisition using the x-ray beam transmission measurements. Unlike MRI andRead MoreWhat Is Magnetic Resonance Imaging?1525 Words   |  7 PagesWhat is Magnetic Resonance Imaging? Magnetic Resonance imaging (MRI) is a test that uses a magnetic field and beats of radio wave energy to take pictures of organs and structures inside the body. MRI gives distinctive data about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan. MRI imaging can also demonstrate issues that can t be seen with other imaging strategies. Magnetic Resonance Imaging (MRI) works by measuring the way that hydrogen particlesRead MoreThe Physics Of Magnetic Resonance Spectroscopy1005 Words   |  5 PagesMagnetic resonance imaging, or MRI, is an applied form of Nuclear Magnetic Resonance spectroscopy (NMR).
