Technology : A Beneficial Driving Force For Providing Quality Patient Care And Assisting Physicians With Complex Cases

If you are this type of doctor you have to make sure all of the scanning images are very clear and readable. Next, you have to decide which images show the healthiest or pathological areas. Then, you have to observe and read over the results and care of the patient during the scanning procedures and make sure you get the correct data for the right person. They

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 opening the body through surgery. MRI lets physicians see through bones and organs. MRI does not expose the patient to radiation, unlike tests that use X-rays. MRI provides an unparallel view inside the human body. It is the method of choice for the

Healthcare has evolved tremendously over the last few decades. Technology, being one of the biggest impacts has reached new heights and has advanced our learning and knowledge to places unimaginable. Many different modalities take place in the health field to ensure the greatest treatment for everyone with improving outcomes. Three modalities that have enhanced and have taken special roles in 3-D imaging include, CT scans, MRI, and Ultrasound; each with their own advantages and disadvantages. These modalities all require training, are cost effective, and take a specific amount of time to obtain all the necessary information. These same modalities have different traits regarding the use of radiation, contrast, evidence

New advances in diagnostic imaging (DI) technology has produced an increased efficiency within DI departments, allowing for an increased number of examinations completed. This increased efficiency however has also lead to an increase in the workload placed on radiologists, the doctor specialized in diagnostic image interpretation, causing an increased wait time for patients to get their images read. The limited number of radiologists throughout the different areas of Canada leads to increased wait times for patients’ results, creating a bottle neck within patient care in the DI department. Although radiologist’s have increased depth of knowledge regarding specialty procedures, as well as a broad range of knowledge regarding all the different diagnostic modalities used, it is not always required. Radiographers, the health care professional responsible for performing the examinations, must also understand the different pathologies as well as their appearance as part of their educational requirements. You,

In fact, medical imaging made it possible to identify diverse abnormalities in humans. These images can be obtained from Computed Tomography (CT), Magnetic Resonance Imaging (MRI), X-Rays, Ultrasound, positron emission tomography (PET), etc. Analyzing these images usually requires special programs and a user to run the software. All the images that are obtained, using different techniques, contain important and useful information for the physician to make a decision. MRIs are widely used by physicians and

Radiology allows physicians to look closely into the interior of the living human body without cutting it open and has transformed the way patients and physicians view health and disease. Radiology is the key diagnostic tool for many diseases that can be located in the brain, heart, and other organs or bone. It has an important role in monitoring treatment and predicting outcome. Radiologists have been strongly associated with technological developments and have been in charge of the evaluation of the strengths and weakness of different investigations. Radiologists have advanced the knowledge of the appropriate unified imaging design to expand clinical effectiveness. They have also been responsible for the performance of these development into the clinical setting and provide the best use of asserts and healthcare resources.

Last of the diagnostic imaging tools is the MRI. MRI, which stands for Magnetic Resonance Imaging, was a technique developed in the 1950?s by Felix Bloch, and is the most versatile, powerful, and sensitive tool in use. The process of MRI was originally called NRI, Nuclear Resonance Imaging, but was found to be to confusing due to the fact that MRI?s don?t use radioactivity and ionizing radiation. The MRI generates a very powerful electromagnetic field, which allows the radiologist to generate thin-section images of any part of the body. Also it can take these images from any direction or angle, and is done without and surgical invasion. Another plus side to the MRI is the time it takes to perform, where as a CAT scan may take 30-60 min. A MRI may only take 15 minutes max. The MRI also creates ?maps? of biochemical compounds within a cross-section of the body. These maps give basic biomedical and anatomical information that provides new knowledge and may allow early diagnosis of many diseases.

According to Dr. Lee, a professor at Baylor College of Medicine, a combination of tools in ultrasound provide a more dynamic way of seeing things in different ways than that of traditional ultrasound. For example, maximum intensity projection lets doctors visualize fetal bony structures, while 3D inversion mode gives them the ability to examine fluid-filled structures. Doctors use these tools in combination when viewing surface details such as features of the babies face, allowing them to search for genetic syndrome. Combinations of these tools make it easier for physicians and parents to understand birth defects and

A poor quality image impedes adequate reading which may lead to mis-diagnosis. For fluoroscopic procedures such as barium enemas, cardiac imaging and the examination of blood supply (angiography), the radiologist is involved in acquiring the individual images that comprise the investigation in addition to radio-diagnosis. However, with Computerised Tomography (CT) and Magnetic Resonance Imaging

A radiologic technologists (radiographers) mission is to produce good-quality diagnostic images for the radiologist to read and give

Transducers can now deliver both 3D/4D and 2D images with just the click of a button. The ultra-thin, target beam provides tissue uniformity, resulting in less artifacts. Current transducers can also take images from two planes simultaneously without rotating the transducer in which takes away the risk of losing tiny objects. Transducers now provide medical instrument navigation, which helps guide medical tools during internal procedures. Unlike old transducers, new technology allows transducers to provide high resolution images, even in the most difficult anatomy. Leading to early detection and treatment of tumors. These improvements have allowed physicals to see things that are a lot smaller and deeper, which were unable to be seen before. With these technological improvements physicians can see in much more clearer definition. “Everyone is so use to ultrasound pictures being fuzzy,” said Tomo Hasegawa, director, ultrasound business unit, Toshiba America Medical Systems. “With enhancement in computer technology, we’re starting to get images that are so clear, people don’t even realize its ultrasound.”

The MRI is an extraordinary machine that changed medical imaging forever, but even more extraordinary is how it functions. Magnetic Resonance Imaging is used to make a detailed image of the human body in order to diagnose disease and injury. It uses a very powerful magnet to align the nuclei of atoms in the body and a variable magnetic field which causes the atoms to produce an image, or resonate. The human body is made of mostly water. Water molecules have hydrogen nuclei that align in the magnetic field. The machine applies magnetic field of about 0.2 to 0.3 teslas, which is about a thousand times stronger than a fridge magnet. The protons in

Medical imaging is a technique used to recreate images coming from different devices. These visualizations of the interior structure of the body are of great importance in regards to the medical field, because these images are used for diagnosing or treating several diseases. In addition, medical imaging is a powerful tool that helps to in analyzing mechanical and chemical properties of an organ or tissue. In fact, medical imaging made it possible to identify diverse abnormalities in humans. These images can be obtained from Computed Tomography (CT), Magnetic Resonance Imaging (MRI), X-Rays, Ultrasound, positron emission tomography (PET), etc.

Chapter 1 is an introduction to the thesis and provides an overview of the relevant current context of medical image interpretation literature and background of topic.

Modern medicine has undergone major advancements over the past years. One of these developments include the capacity to retrieve crucial information about the human body and its health beyond the use of manual diagnostic techniques. This is referred to as Medical or Diagnostic Imaging.
