The primary focus of this report was to establish, if CT is better than MRI in evaluating head injuries, and if one of the modality is specific in diagnosing particular brain injuries for a patient in acute and chronic phase. It was of importance to undertake this work, in order to emphasize their purpose and limitation, and find out while CT scans are currently the standard test used to diagnose brain injury.Computed tomography (CT) and magnetic resonance imaging (MRI) are currently two of the latest modality for producing computerized images of the brain injuries. Both CT and MRI give vastly more information about the brain injuries. However, CT is the standard method of investigating an unconscious patient with a traumatic head injury as it most sensitive to acute haemorrhage and bone fractures. CT is more widely available twenty-four hours a day, seven days a week unlike MRI.
Another advantage of having ultrasound is using the Colour Doppler Ultrasound, which is an imaging technique that provides a visualization of what is happening in the body. It provides a coloured image that shows all the cancer cells that are spreading in the body, making it easier for the doctor to locate the place of the cancer spreading. In conclusion, because of the significant speed, safety and cost of diagnosing medical conditions, the New Zealand Medical Council is urged to give the nomination of ultrasound its favourable consideration fort the most important piece of medical equipment.

Medications can help with constricting open varices and for severe cases, endoscopic surgery can be performed. Another condition associated with HCV is thrombocytopenia, wherein the body produces a low platelet count. This can be a very serious condition for those with bleeding disorders, thus it is best to consult your doctor as soon as possible. Mood changes Most HCV patients experience depression, irritability, insomnia and difficulty in concentration.
It has become an essential intraoperative tool to improve safety in surgical procedures and helping minimize postoperative deficits. It has allowed surgeons to accept high-risk patients who might have been otherwise denied for a surgical procedure. There are many intraoperative monitoring modalities used to assess different part of brain, spinal cord, and the peripheral nervous system. The strength of each modality is able to offset the limitations of other monitoring modalities, and when combined together, they provide a comprehensive picture on the complex spinal cord function.

Augmented reality actually has given a lot of contribution to various applications using 3D real environment.
I choose this article “What is MRI? How does MRI work” by Mathew Kalapurayil because I found these devices to be interesting and also extremely useful to healthcare providers because the vast number of patients saved by a scan which could detect and diagnose diseases, without any physical harm or side effects. The advantages of MRI scan include its careful precision in noticing physical irregularities of the body. In medical technology, identifying the disease is not based only on one result rather it is a collection of information shared by a group of specialists; one example of this is the radiologists who are skilled doctor. The radiologist is trained expert who understand and interpret the MRI information.
RF is relatively safe but it also has its possible complications. A special probe is directed in the tumor under the help of radiographers who guide the probe using imaging techniques such as magnetic resonance imaging (MRI), computed tomography (CT), and ultrasound (US). A radiofrequency wave is passed through the trobe to heat the tumor tissue which is near the needle tip to cause tumor ablation. Thermal

The current lines of fetal tissue research seem to promise, or at least imply, similar results. This is an area of research that has a very significant importance in our time and is one that should be followed closely. Many researchers and I believe that we are on the edge of a great new discovery that will bring hope and comfort to many people.
(1) The current strategy for the treatment of Glioblastoma Multiforme is generally palliative treatment, including standard chemotherapy and surgical resection, and radiotherapy. GBM often exhibits a high resistance to both chemotherapy and radiotherapy. (2) Astrocytes are star-shaped glial cells in the brain and spinal cord. They are the most abundant cell of the human brain. Astrocytes provide neurons with metabolic support, control local blood flow, and regulate the maintenance of synapses.
If POCT were to replace blood services, there would be a huge impact with regards to CPA. It can be concluded that POCT should be used in addition to laboratory testing. POCT may be of value in emergency departments that are faced with a high volume of patients, and may help in shortening the patients stay in hospital (Hsiao et al, 2007). POCT provides a timely alternative to laboratory testing and will be driven by many of the same factors that affect clinical laboratories in the foreseeable future.
