Medical imaging

MRI stands for Magnetic Resonance Imaging. Dictionary.com defines it as a noninvasive diagnostic procedure employing an MR scanner to obtain detailed sectional images of the internal structure of the body. From my own prior knowledge, Magnetic Resonance Imaging is a technique that uses a magnetic field and radio waves to create detailed images of the organs and tissues within the human body. The idea for Magnetic Resonance Imaging was initially conceived by Damadian in 1971 after he recognized…

The Technology of Radiology There is a lot of technology included in Radiology. Radiologists are medical doctors that diagnose and treat diseases “using medical imaging technologies.” They use many different tools and machines to diagnose and treat people. Some of the technology used in radiology are catheters, wires, small instruments and tools, scanners, and remote viewing systems. The three most common scans are CT, MRI, and PET. There are many different types of x-rays, the most well known…

Nuclear energy plays an important in the medical field. Nuclear energy in medicine has been discovered more than 50 years ago and it has been widely-used ever since. The first use of nuclear energy in the medical field is for medical imaging which is a way of creating visual representation of what is going on in our body. Medical imaging began when Wilhem Rontgen discovered x-ray in 1895. However, at that time, the dangers of radiation was not known yet. Fast forward about 20 years later,…

Many different modalities are used in interventional imaging such as: computed tomography, fluoroscopy, magnetic resonance, and ultrasound (Farrell, p. 375, 2014). With the advances in imaging technology, interventional radiology (IR) is a quickly growing, and becoming a popular advanced specialty. IR is a form of minimally invasive imaging that is used to assist in procedures. Interventional radiology can be used to treat as well as diagnose disease. There are many types of disease that can…

expertise of a radiologist together with the knowledge of therapeutic intervention using advanced techniques using a range of imaging guidance modalities such as X-ray fluoroscopy, ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) to accurately treat a medical condition. By the same token, Baum and Baum (2014, p. S76) implies that using the same diagnostic imaging tools that transformed medicine also assist the physician by applying…

1.Please explain how medical magnetic resonance imaging (MRI) exploits the magnetic properties of the nucleus. MRI exploits the process known as nuclear magnetic resonance (NMR). In fact the technique used to be called simply NMR or NMR imaging, but the “nuclear” was dropped because of the connotation of radiation hazards from unstable nuclear sources, although there is no logical rationale for such fear. In NMR, a sample of material is placed in a strong magnetic field. The nuclei in the sample…

and one of the major organs in human body strongly correlated to neural and the skeletal system it plays an important role in various oncological, neurological and orthopaedic studies. 1.2.1. Vertebra Localization in CT Images Not only studies or medical applications involving the investigation of vertebral body pathologies,…

for a short period of time change the way x-rays or other imaging devices act together with the body. When put into the body before the beginning of an imaging exam, contrast materials cause certain structures or tissues in the body seem different on the images than they would if no contrast material had been dispensed. By advancing the view of particular organs, blood vessels or tissues, contrast materials aid physicians identify medical…

Diagnostic testing for the patient with acute appendicitis included magnetic resonance imaging (MRI) and a Karl Storz image of the appendix. An MRI is a non-invasive technique in which the patient is placed in a magnetic field to examine their body anatomy (Pagana & Pagana, 2014). This form of diagnostic testing provides healthcare professionals with imaging on a specific area of the body with the ability to differentiate between blood vessels, necrotic, and healthy tissue (Pagana & Pagana,…

Through The Eyes of a Diagnostic Medical Sonographer A diagnostic medical sonographer is a profession in which special imaging equipment is used to direct sound waves into a patient’s body, which can then asses and diagnose various medical conditions. Most people assume a sonographer is someone who only works with pregnant women and performs ultra sounds. The majority of people do not realize the various modalities involved in sonography. There are about eleven different areas of study…
