The article written by Shagam entitled “Functional Magnetic Resonance Imaging” and published in the July-August 2007 Issue of Radiologic Technology proffered pertinent issues relative to understanding the process and importance of functional magnetic resonance (fMR) imaging, particularly focusing on the physiology of cognition, memory, emotion and creativity. The purpose of the essay is to critique the article in terms of encompassing crucial elements and in exuding strengths or eminent weaknesses in achieving its defined objectives and in arriving at valid conclusions.
Initially, the author did not explicitly state the purpose for writing the article since a discussion on what fMR imaging is in general was immediately presented. It could thereby be presumed that the article is a descriptive narrative and qualitative study that presents crucial concerns relative to fMR imaging, as a whole. As observed, the author enumerated a fourteen point learning objective that readers should be able to exemplify after reading the article.
The importance of the article in the field of imaging, detection, or future trends is relevant as it provided vast applications for medical practitioners in terms of accurately allowing “researchers and clinicians literally to watch the brain in action. To create these images, researchers measure the fluctuations in brain metabolism and blood flow that occur in response to sensory and cognitive stimuli”....
477). The key concepts that were presented included an overview of fMR imaging; a description of blood-oxygenation-level dependent contrast; its clinical applications, patient safety and research facilities. Likewise, fMR imaging’s manifestation and implication as a window to the brain was expounded in its role in areas such as clinical diagnosis, treatment, and monitoring. The strengths of the article therefore could be evaluated in terms of providing the contents in a clear structure complete with headings and sub-headings; the use of figures that enhanced illustrative details of examples of fMR imaging weighted images, complex molecule, as well as activation process and healthy controls; the use of tabular illustrations that highlight summarized details; and contentions supported by a total of 40 references from reputable and authoritative sources. It is commendable to note that all references were published within the 10-year time frame where the oldest source was dated in 1998; therefore, readers are assured that contents are still applicable in contemporary setting. The author likewise used a comprehensible language to enable readers from various academic backgrounds to understand the contents being discussed. Relevant terms were duly defined and significant contemporary statistics were provided to increase credibility and validity of the discourse. On the other hand, one weakness was likewise noted: the authoritativeness of the author herself, being a freelance medical writer and not an active medical practitioner within the field of radiologic technology. Therefore, it is presumed that all information provided was researched and no professional information ...Download file to see next pagesRead More

Ultrasound is one of the commonly employed Image-Guided Radiation Therapy (IGRT) technologies that use high-frequency sound waves to produce images of the internal structures in the human body. In ultrasound a transducer is used to produce high-frequency sound waves, which are encased in a probe and applied to the surface of the skin. Depending on the impendence of the internal structures based on the density of the tissues these waves are partially reflected as an echo. The time taken by the echo to be reflected back to the source is used to measure the depth of the tissue interface. Images are generated along the beam line...
