[MSIT] the fact that X-rays are not used in MRI make it much safer for the patients as the radiation hazard is not there. Also, MRI provides greater contrast between the different tissues in comparison to a CT scanner offering more detailed anatomical review, better diagnostics, and improved interventional radiology. By adjusting the contrast mechanisms and other imaging parameters, the MRI allows the radiologist to obtain a highly detailed image of a particular region of study. Particularly, the MRI is highly effective as a diagnostic tool for studying the anatomy and abnormalities in the brain, spinal column and other vital regions enabling the easy identification of pathological tissues. The availability of super magnetic contrasting agents has further improved the visualization and the quality of the images. [Joseph P. Hornak]
Interventional Radiology
By the 1970's, new advancements and improvements in imaging techniques extended their application to interventional procedures in different clinical settings. Primary among these is vascular interventional radiology involving procedures such as angiography, angioplasty, chemoembolization, RF ablation (radio frequency ablation), Biopsy, etc. Today, these aforementioned interventional methods have greatly helped patients in the treatment of a wide range of cardiac conditions and cancer care. Guided procedures such as angioplasty are a quick, immediate and less invasive treatment for people suffering from blocks in heart valves. Catheterization procedure such as AV node ablation is one of the common methods for treating electrophysiological defects in the heart muscle. In cancer care, imaging guided biopsies are used to obtain tissue samples without affecting adjacent tissues. For example Transjugular liver biopsy is used to identify hepatic carcinoma without having to go through the Glisson's capsule. This procedure reduces the chances of liver bleeding. Using radiographic guidance Transcatheter chemoembolization, gene therapy and tumor ablation procedures are done effectively improving the quality of life for the patients. Similarly, image guided aspiration procedures are very effective alternatives for fluid draining under less invasive settings which would otherwise involve surgical raining. Currently Radio frequency ablation techniques are in vogue in the treatment of liver cancers and the...
Harnessing Unstructured Data in Radiology The harnessing of unstructured data is vital to moving the field of radiology forward. There are methods used for the mining of unstructured data, with one of the most common being Natural Language Processing (NLP). However, there are some difficulties with the use of NLP in the radiology field, because NLP lacks the capacity to analyze free-text radiology reports and images. There is too much uncertainty
Radiology and Cyberspace The creation of 'cyberspace,' or the sharing of information through email, on the Internet and on websites, has had a profound impact on nearly every field of human endeavor. Medical science, and particularly Radiology, has been particularly affected and enhanced by new technology. Radiology, by its very nature, has always been a leader in the use of emerging technology in the medical field. Now, new technology developed during
He proposed this technique as the solution to the problem of why some people do better than others in certain tasks, He likewise suggested cataloguing the differences in the size of the functional areas among individuals and correlating these with different talents and skills (Krotz 2001). Van Essen believed that his technique would ultimately lead to what makes people human or unique. Brain mapping charts and determines specific areas, such
History of Magnetic Resonance Imaging (MRI) Getting an MRI scan may someday become as common as getting an X-ray. - Davis Meltzer, 1987 According to Gould (2004), on July 3, 1977, an event took place that would forever alter the landscape of modern medicine, although outside the scientific research community, this event hardly attracted any notice at all. The event in question was the first MRI exam ever performed on a human
Very near the beginning of World War II, Karl Dussik began exploring ultrasound technology for diagnostic purposes by "attempted to locate brain tumors and the cerebral ventricles by measuring the transmission of ultrasound beam through the skull" (Woo 7). This experiment produced disappointing results, and the development of this apparatus was not pursued further because of the elaborate set-up, and lack of clear visual representations of the brain. However, at about
Future of Radiology and X-Ray Technologists By tracing the historical development of radiography as a distinct field of diagnostic treatment, along with the evolving role of X-ray technologists in the delivery of quality health care within the public hospital/private practice model, it is possible to identify the attributes of this field that make it a foundational science within the practice of modern medicine. The ever-expanding ranks of X-ray technologists now
