We can detect relatively small temperature elevations before any irreversible tissue damage by

All MR images were evaluated in T2WI and DWI for site, size, and signal intensity of the

Soft tissue structures such as heart, lungs, liver and other organs are clearer and more detailed with MRI when comparing with the other methods.

The use of high spatial resolution MR imaging at 3T, will provide the highest post-contrast imaging quality and temporal resolution of the pancreas, which is important when evaluating small focal pancreatic lesions [4], and looking for vascular involvement ort

Magnetic Resonance Imaging is also known as MRI. This computerized device is used for scanning the

According to (Morris and Liberman, 2005), MRI is principles technique which has a different physical from mammography and ultrasound. It indicates the protons water density in tissues including its magnetic interactions with molecules in its local surroundings. Magnetic interactions affect on MRI signal, that influences how fast the water protons can get back to equilibrium after receiving the radio-frequency energy from RF coil. MRI Parameters system can adapt to switch of T1 and T2 weighting that is providing image contrast to be formed.

NMR is a form of spectroscopy that utilizes external magnetic fields and signals to identify the chemical structure of organic molecules, creating a gradient image. Through applying an applied Radio Frequency, the proton is able to flip into higher energy states, and then relax. This process is recorded by a NMR Spectrometer, and the difference in energy provides it with a certain NMR Signal. The difference in the magnetic fields of the allows for a gradient image of the area. There are various types of imaging that are useful for fast imaging or 3D imaging such as Gradient-Echo Imaging or Volume Imaging. Some other applications of the same principles that apply to MRIs mainly relate to the identification of organic molecules such as Protein Folding and Drug Development. Although MRI is a relatively safe and harmless process as opposed to other forms of imaging such as X-rays, certain aspects still pose a risk to patients

the body and makes use of the property of nuclear magnetic resonance (NMR) to image

Unlike CT scans, MRI works without radiation. The MRI tool uses magnetic fields and a computer to take high-resolution pictures of the bones and soft tissues. It has the ability to diagnosis problems such as tumors, bleeding, tissue damage, and can provide additional information from other commonly used scans such as CT scans and X-Ray. It is the method of choice for the diagnosis of certain diseases, disorders, and injuries. MRI is safe for most

An increased temperature can take a major toll on a patient’s ability to heal. Studies have shown

Advancements have allowed the modality of MRI to come so far in a few short years. The main advancement that has occurred is the actual machines themselves. The machines have come so far in the fact they allow for so much more detail. The development of higher field magnets allows for the achievement of great image quality and spatial resolution (Jolesz,2015). This shows the most detailed brain anatomy for example. By being able to do this, the surgeon can know not to disrupt certain brain tissues and only operate on the unhealthy tumor matter. The MRI machine shows the surgeon in great detail that he or she has gotten all the tumor and know without uncertainty that all is gone (Jolesz,2015). The newer MR sequencing parameters allows for what modern neurosurgery needs for morphology and function during

RapidArc is an advanced technology which is used to deliver intensity modulated radiation therapy(IMRT) and is often used to treat head, prostate, and neck tumors and other cancerous tumors. This is done by using photons which are generated by medical linear accelerators, it is very fast and precise, it is also capable of protecting the healthy tissues while focusing the radiation on the tumor. each treatment ranges between 1 to 2 min to complete, hence it reduces the amount of exposure of the patient during the radiation treatment. The radiation dose is delivered using the computer-generated images. During the treatment, the patient is surrounded by a linear accelerator which rotate 360 degrees, it delivers the beam of radiation directly to the tumor as it rotates. This beam is shaped to conform the shape of the tumor. The beam is continually shaped in order to coincide with the shape of the tumor, by doing so it

Magnetic resonance imaging (MRI) is a technique that uses a magnetic field and radio waves to create detailed images of the organs and tissues within your body. MRIs are largely used in the medical field today because of their ability to create detailed images of the human body which can be used for diagnostic purposes. In 1971 a paper in the journal Science Raymond Damadian, an American physician and professor at the Downstate Medical Center State University of New York reported that tumors and normal tissue can be distinguished by nuclear magnetic resonance (NMR). He suggested that these differences could be used to diagnose cancer, though later research would find that these differences, while real, aren’t consistent enough for diagnostic purposes. Damadian 's initial methods were flawed for practical use, relying on a point-by-point scan of the entire body and using relaxation rates of the tissue in your body, which turned out not to be an effective indicator of cancerous tissue.

RFA is a technology in the management of liver tumours. High-frequency alternating current (400-500KHz) is delivered through the electrodes,

Last of the diagnostic imaging tools is the MRI. MRI, which stands for Magnetic Resonance Imaging, was a technique developed in the 1950?s by Felix Bloch, and is the most versatile, powerful, and sensitive tool in use. The process of MRI was originally called NRI, Nuclear Resonance Imaging, but was found to be to confusing due to the fact that MRI?s don?t use radioactivity and ionizing radiation. The MRI generates a very powerful electromagnetic field, which allows the radiologist to generate thin-section images of any part of the body. Also it can take these images from any direction or angle, and is done without and surgical invasion. Another plus side to the MRI is the time it takes to perform, where as a CAT scan may take 30-60 min. A MRI may only take 15 minutes max. The MRI also creates ?maps? of biochemical compounds within a cross-section of the body. These maps give basic biomedical and anatomical information that provides new knowledge and may allow early diagnosis of many diseases.

MRI technology is a useful technique in the medical industry, there are many advantages to its use and for the most part the disadvantages of its use are minimal. They are great because they provide very detailed diagnostic pictures of most of the important organs and tissues in one’s body. They are also capable of showing unique information that other tests are unable to show. They are generally painless. Furthermore, they do not use radiation and are therefore suitable for use in children and pregnant women. Although there are many good attributes to MRI’s, there are still disadvantages to its use. For one, many people are claustrophobic and being in an MRI can become very uncomfortable for them. In addition, the MRI makes a tremendous amount of noise. Often patients are given earplugs or stereo headphones in attempt to muffle the noise.
