for diagnostic purposes. The diagnosis from a radiographer’s image can affect, determine the treatment and care of a healthcare team. Wide ranges of imaging methods are used these include Ultrasound, X-ray, Fluoroscopy, Computed Tomography, Magnetic Resonance Imaging. Ranges of dyes or contrast agents are sometimes used to show…
Measuring Brain Activity to Reconstruct Visual Experiences The principle of perpetual evidence states that brain activity is not random, and that the processes we use in mental visualizations are used in visual perception as well. The firing of neurons that occurs when one imagines shooting a free throw are the same neurons that fire when actually doing so. The fact that brain activity is complex and calculated has helped scientists see how the brain functions, and what areas are associated with…
or less serious, it could come for once and never come again. For these reasons, diagnosing Multiple Sclerosis (MS) is not straightforward, however, there are several tests that could determine whether you have it or not. The first one is the Magnetic Resonance Imaging (MRI). MRI is a diagnosing tool that visualize the brain, spinal cord, or other parts of the body in a most sensitive non-invasive way.2 MRI is particularly useful in detecting central nervous system demyelination (removal of…
Interventional radiology is considered a specialized modality of radiology that deals mostly with invasive image-guided procedures. With advances in technology, interventional procedures can be performed on several areas of the body with success in conjunction with using live x-rays during exams. Cerebral aneurysms often can be in susceptible areas of the brain, and usually, are considered somewhat high risk in nature. The use of endovascular coiling can prove to not only be successful, but…
Ultrasound (US) and MRI are commonly used in the clinical setting to confirm the presence and location of tendon thickening or other structural change and associated findings (Scott et al., 2013). However, although their clinical utility, both US and MRI are subject to artefacts and may reveal poor interobserver and intraobserver reliability. In comparison with MRI, ultrasound has the accuracy and sensitivity of US (0.63–0.83 and 0.68–0.87, respectively) and MRI (0.68–0.70 and 0.50–0.57,…
technology of mapping the brain can predetermine irregularities in the brain such as frontal lobe damage (p.26). Computer axial technology (CAT) scans combine with information on X-Ray, and Magnetic resonance imaging (MRI) depicts a three-dimensional view of the brain in doing so, a very detailed image of the brain which illustrates areas within the brain that is damaged or diseased (Gaines and Miller, 2011, p.27). Furthermore, a positron emission tomography (PET) scan aids in researchers being…
The extensive recent research utilizing neuroimaging techniques to study pain in healthy subjects has many clinical implications for pain diagnosis and treatment. For the sake of brevity, this response will focus on fMRI (functional magnetic resonance imagining), a method that surveys changes in blood flow assumed to be reflecting alterations in neural activity and maps them to an anatomical representation of the patient’s brain (Borsook, Burstein et al. 2004). The culmination of several fMRI…
Bone is a common site of metastases for many primarily malignant tumors, being the third location after liver and lung [5]. Bone metastases are a major clinical concern as they can deteriorate the bone structure causing pathological fractures, vertebral/spinal instability, severe pain, spinal cord compression, functional impairment and increased mortality. The vertebral column being the most frequent site of bone metastasis and one of the major organs in human body strongly correlated to neural…
Alternative Imaging for MRI in MS MRI is a great tool for medical imaging and widely used for Multiple Sclerosis (MS), but it has some limitations in lacking specificity1. New emerging techniques such as transcranial magnetic stimulation (TMS) and optical coherence tomography (OCT) have the potential to address issues not resolved by current MRI techniques. TMS is a non-invasive technique used for monitoring the central nervous system (CNS) activity and response in a pain-tolerated manner. It…
understand how does the five imaging technologies work. The first imaging technology is called MRI (Magnetic Resonance Imaging), this technology is proven to evaluate your bones, breasts, blood vessel, brain tumor, and organs in the abdomen, chest, and pelvis. MRI uses radio waves to detect your tissues and other organs inside the body. Since MRI is a powerful technology, the scanner uses force and strong magnetic to see the images of your body organs in detailed. Second is X-rays, which is told…
