The Role of Computer-Aided Detection in Diagnostic Medical Imaging

One of the main reasons for choosing a healthcare career in todays society, aside from the basic need for a self sustaining income, is the opportunity to make differences in peoples lives. With the demand for healthcare professionals and alternative medicines on the rise, so is the need for adequately educated trained personnel. Diagnostic Medical Sonography is becoming an increasingly attractive alternative to radiologic procedures such as x-ray and magnetic resonance imaging (MRI). Accounting for approximately 50,300 jobs in the United States in 2008, compared to the 214,000 jobs held by radiologic technicians, according to

Within PFCH, the Radiology Group leverages these technologies to view the interior of the physical human, enabling them to provide both diagnosis and treatment. The graphical capability as well as the ease of use that the Apple Macintosh operating systems provide PFCH’s staff not only the ability to support the growing need of MRI’s (Magnetic Resonance Imaging), CT Scanning (Computed Tomography) also known as Cat Scan, Projection Radiography, Mammography, PET Scanning (Positron Emission Tomography) as well as Sonograms. PFCH currently employs Modality Viewing Stations and two Apple 30 inch monitors.

I have always desired a career that would allow me to improve the lives of those around me while caring for a family of my own. I desire to feel successful through continual learning and challenge. Radiologic Technology will provide me this with ever changing tasks with different circumstances and challenges that require problem solving, critical thinking, and determination. Radiologic Technology will allow me to have interaction on a personal level with patients and their families and provide the opportunity to improve their lives by searching for the things that don’t appear on the

When it comes to medical imaging, there are several different options to choose from for different testing. There are similarities and differences; pros and cons to each. This paper will discuss MRI, CT, and ultrasound. They each have important things to know regarding radiation dose, cost, and reasons to use one over another.

The articles by Branstetter, Bartholmai and Channin (2004) and Kohli, Dreyer and Geis (2015) make an important contribution to the knowledge base of radiology informatics. The overall delivery of health care has benefited greatly from the technology explosion that has affected almost every industry. This benefit has been highly visible in the practice of radiology. The introductions of radiology information systems, voice recognition dictation systems, and picture archiving and communication systems (PACS) led to significant advancements in workflow efficiencies. To this end, both articles examine informatics innovations of the past several decades that have immensely enhanced

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

Radiologic Technologist have a huge role when it comes to the diagnoses of a patient, it is because of their work that doctors are able to have an accurate diagnoses (Institute for Career Research 2010)

Computed tomography (CT) degree programs teach students how to use X-rays, technology and software to gather anatomic information from patients. CAT machines take pictures of a sectional plane of the body and present it as a 3D l image.

Up until the 1970’s, physicians had access to several different imaging systems such as CT (Computed Tomography) and MRI (Magnetic Resonance Imaging), but these types of imaging only allowed physicians to see the internal structures of the body, not how they functioned. With the advent of PET, the physicians are now able to see and record these functions.

Radiology is where the frontiers of

To me practicing medicine has always been a challenge of gathering information, assessing the problem, focusing my attention and solving the puzzle; the combination which as I later discovered, encompasses the very core of radiology.

The first modality is radiography which utilizes x-rays to generate images. Mammography and Computed Tomography (CT) also use x-rays. Depending on which test is used, hard or soft tissue can be visualized. Classical radiography is used to create images of hard tissue like bones, and can be used to diagnose broken bones. Radiography can provide projections of the human body that showcase the depth and position of the anatomy. Screen-film radiography and digital radiography have spatial resolutions of .08 and .17 mm respectively. Temporal resolution for radiography is typically less than half a second. Despite the fact that radiography is relatively cheap and fast compared to other modalities, there are concerns of being wrongfully or overly exposed to radiation which may lead to an increased risk of cancer in the patient. Mammography is a specialized form of radiography that is designed to image breasts to aid in diagnosing breast cancer. It can be used to showcase glandular and fatty tissues, the skin line, and any cancerous or calcified masses. Mammography is the preferred method of detecting break cancer due to its high sensitivity and benefit to risk ratio. CT is another form of radiography that can create highly detailed, 3-D

As with any other radiographic method, optimum interpretable diagnostic images can only be achieved with careful quality assurance in patient positioning, in selecting appropriate exposure parameters and during processing.

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.
