Computed Tomography Research Paper

Sonography is a non-invasive medical procedure that uses the echoes of high-frequency sound waves to construct an image of internal organs or body structures. The employment rate is is expected to grow 26 percent from 2014 to 2024. Since ultrasound is non-invasive, it is more encouraged than other methods so the career is always in demand. Diagnostic medical sonographers duties are to prepare and maintain diagnostic imaging equipment, taking a patients medical history, answering questions about the procedure, operating the equipment, review images and test results, know the difference between normal and abnormal images, analyze diagnostic information, record findings, and keep track of patient records. Hospitals, offices of physicians, medical

Computed tomography is used in the emergency setting, but it is not useful in predicting short- or long-term outcomes in sports related concussion. Magnetic resonance imaging (MRI) is more sensitive than CT, but the correlation between focal structural lesions detected by conventional MRI is controversial since T1- or T2-weighted MRI images may not be sensitive to the neuropathology of milder injuries There has been increasing interest in diagnosing and prognosticating after concussions using susceptibility weighted imaging (SWI), diffusion tensor imaging (DTI), magnetic resonance spectroscopy (MRS) and functional magnetic resonance imaging (fMRI).

Computed tomography known as CTs uses x-Rays to look through your body. These are the same x-Ray which are used to make plain x-Ray pictures. Then the computer puts together those plain films to get pictures of your inside. CT scanners bombard the human body with x-ray beams, which can damage DNA and create mutations that spur cells to grow into tumors. The problem with CT scans from health point of view is that they involve exposing the patient to ionizing radiation, which results in an increased lifetime risk of cancer. A single CT scan exposes the patient's body to 200-1000 plain x-Rays film. The bigger the body part, the more radiation needed.

Computed tomography (CT) scan is a non-invasive medical imagery procedure that combines the use of x-rays and computer to generate tomographic parts of the area scanned. CT scan are also referred as CAT scans and they produce detailed images of structures inside the body such as internal organs and bones. CT scans can be used for treatment, diagnose and monitor condition. CT scans in screening and diagnosis are to detect cancer, determine whether a cancer has spread throughout the body or returned to the body after the treatment, and to determine effects of heart attack or myocardial infection on areas of the heart. Identify areas of the heart muscles that would benefit from a procedure such as angioplasty or coronary artery bypass surgery.

Ultrasound is the first imaging test performed upon the suspicion of Wilms tumor because of its efficiency, safeness, and good imaging characteristics. Ultrasound uses sound waves to create the images of the organ, meaning there is no radiation involved. It gives a good view of the organs in the abdomen, as well as detecting tumor thrombus (tumor growing into the main veins coming out of the kidney). Ultrasound is also used to distinguish Wilms tumor form hydronephrosis (Eisenberg, 2016). Computed Tomography (CT scan) creates quick and detailed cross sectional images of the body’s anatomy, and is one of the most useful tests in detecting mass in the kidney.

Computed tomography (CT) is a modern imaging tool that combines X-rays with computer technology to produce a more detailed, cross-sectional image of patient’s body. A CT scan lets the doctor see the size, shape, and position of structures that are deep inside patients’ body such as organs, tissues, or tumors. The doctor need to use CT if the patient has a problem with a small, bony structure or have severe trauma to the brain, spinal cord, chest, abdomen, or pelvis.

CT scan also known as a CAT scan stands for computerized tomography. It takes 3-dimensional pictures of the inside of the body. CT scans can be used to view, monitor, or diagnose things such as: muscle and bone disorders, cancers, heart disease, tumors, infections, blood clots and internal injuries. The procedure is done within a scanner that is hollowed out (donut shaped); a table will slowly move you into the opening of the scanner while the X-ray tube inside the scanner rotates around the body. You will need to remain still for up to thirty seconds during each scan. The scan is painless and you will be alone in the room during the scan, but the technologist can see, hear, and speak to you at all times. The reason the technologist must leave the room is because there is radiation exposure involved, which could increase the possibility of cancer.

As a Radiologic Technology student it is important that you make a good impression of yourself at all your clinical sites. It’s essential that you thrive for ethical behavior and have a professional performance. Being a student having a great attitude and performance will help you to succeed and improve significantly.

The CT scan is a machine that uses 360-degree x-ray beam and computer to produce images that allows for cross-sectional views of body organs. Hage and Atkins indicated that the CT scan debuted in the 1970s; however, it was not until the 1990s when the machine became more affordable that the use of the CT scan become more popular. The affordability of the machine has turned it into a hot commodity in all modern hospitals and even outpatient services.

CT scan is a computerized tomography, it is when slices of images are put together to make up a three-dimensional image of the body produced using an advanced x-ray. It is used to diagnose medical diseases. It has improved widely to provide comfort to patients as the scan can be done quickly. It displays high-resolution images assisting doctors to make diagnosis. For example, the CT scan can help doctors to visualize small nodules or tumors, which they cannot see with a plain film X-ray.

Computed Tomography is a combination of x-ray technology and computer. It is a scanner that moves around the patient and mathematically assembles an image. The color produced depends on upon the amount of radiation absorbed. CT is helpful in the evaluation of bones and soft-tissues.

An Electroencephalogram is the measurement of electrical activity in different parts of the brain and the recording of such activity as a visual trace. One important advantage is the ability to see brain activity as it unfolds in real time, at the level of milliseconds. One disadvantage is that it's hard to figure out where in the brain the electrical activity is coming from. A CT scan is a special X-ray tests that produce cross-sectional images of the body using X-rays and a computer. One advantage is that in a CT image, overlapping structures are eliminated, making the internal anatomy more apparent. CT images allow radiologists and other physicians to identify internal structures and see their shape, size, density and texture. One disadvantage

Being able to save lives are important matters around the world. The ability of medical imaging is proven to increase patient's survival and a healthy life. Throughout this research there are numerous important facts of each imaging technologies. In contrast, patients need these technologies to help reduce death rates. Moreover, medical imaging will continue to improve and be able to help adults and children in the long run.

X-rays are of two kinds within the ems, the two kinds are the soft x-rays and the hard x-rays. The soft x-rays as the name suggests refers to a higher and bigger wavelength compared to hard x-rays but has a very small wavelength compared to the others and one of the largest frequency and energy but lesser than the hard x-rays. The wavelength starts at 10-7 to 10-10 meters and the average size is between a protein and a water molecule, the frequency of soft x-rays is between 1016 and 1018 and the energy ranges from anywhere between 102 and 104 electric volts. The hard x-rays have lesser wavelength with less size but higher frequency and energy. The energy starting from 104 and going up, and the frequency starting from 1018 and going up from

This issue can be mitigated by using dual­energy CT scanners, which enable imaging of patients’ tissues at two different voltages, facilitating comparison of results from two separate detectors. These scanners also enable tissue evaluation at varied energy levels, and further improve the accuracy of determination of stone composition(3,75).
