X-rays is one type of electromagnetic radiation that can send waves through the body which makes us see through the body tissue but it doesn’t go through the bone. Therefore it is used in hospitals to see if a person has a broken bone or any diseases. Because it can go through clothes and the human skin it is also used in airports to see if anybody has a knife or anything dangerous with them. X-rays were first discovered by German scientist Wilhelm Conrad Roentgen in 1985. Roentgen found x-rays…

Introduction An MRI (or Magnetic Resonance Imaging) scan is a radiology technique that uses a large magnet, radio waves, and a computer to look at organs and structures inside our bodies. Single MRI images are called slices can be stored on a computer or printed on film. An MRI combines images to create a 3-D picture of your internal structures. The MRI scanner is a tube surrounded by a huge circular magnet. The patient is placed on a moveable bed that is inserted into the magnet. An MRI…

For my three health careers I chose radiologist, pediatric oncologist and athletic trainer. I do not necessarily want to go in the medical field, but if I were to I would want to work in one of these three careers. All three jobs require skills, reasoning and intuitive thinking. You might find yourself in a situation that demands fast thinking and problem solving, so you need to be prepared. The first career I chose was a radiologist. To become a radiologist you must obtain a Bachelor's Degree…

discussing how Medical Imaging uses wave behavior, why it is needed, and how it captures information and energy. I will also be explaining the differences between the types of Medical Imaging and how the MRI Scan is used in the medical field today. Understanding Medical Imaging Medical Imaging has several different technologies that are used to view the human body. There are different types of Medical Imaging such as MRI, X-ray, CT, ultrasound, mammography, molecular imaging, and Pet Scan.…

team. All these developments over countless decades has led to the ability to diagnose and treat cancer earlier and has saved thousands of lives in the process. [14] [15] 2.2 Basic Processes of Magnetic Resonance Imaging (MRI) As previously mentioned MRI is such a pioneering imaging technique it has aided in the diagnosis of early health conditions and aliments and helped to save millions of lives globally. The basic fundamentals of the principles of MRI use some basic physics to more complex…

The best imagining device that would be best to use to localize the tumor in the man’s brain is the MRI. This is because the MRI, which is also known as the Magnetic Resonance Imaging, is a scanner that uses a powerful magnet and radio waves linked to a computer to create remarkably clear and detailed cross sectional images of the body. The MRI machine can be used to view, monitor or diagnose various things. It can be used to identify and monitor abnormalities of the brain and spinal cord, and…

How exactly do medical imaging and geometry relate to each other, you may ask. They are certainly different things, but maybe not as different as people might believe. The property that connects these two subjects is 3D reconstruction, which plays a major role in the geometry aspect of medical imaging. First of all, I should explain specifically what 3D reconstruction is: the use of numerical approximation to rebuild 2D images by a computer taking the 2D data slices, reading the data, and…

Numerous articles support either modality. The research will be based on the analysis of the different articles and criticising the validity of each argument. They both share similarities in the patient preparation. CT colonography as well as barium enema require bowel preparation, the bowel need to be free from any faeces as its presence can mimic pathology and impair diagnosis. CT colonography offers cross sectional images and allows three dimensional reconstruction. This feature results in…

One beautiful, sunny day in late fall when the leaves were changing colors and there was a little chill in the air, my sister and I were in her jeep with our mom scouring the area for sales. Tonya, my sister, treated us to Hardees biscuits to eat while on our search. We were all excited about different items we purchased from the various sales. The day was feeling like another normal day to look for yard sales with my family. As I stared out the window, thoughts of the peaceful day flooded my…

It was recorded that 12 out of 35 patients, suffered from extrahepatic tumour. This was revealed by PET/CT combined and by CT scan single-handedly. The extrahepatic tumours in two of the patients were not detected by PET and PET/CT; those were recorded to have node of 2 –cm lymph in the hepatoduodenal ligament. It is furthermore, true that both forms of the scans (CT and PET/CT) reported extrahepatic tumour in patients that did not have it at all. The CT scan reported it in 3 out of 23 patients,…
