Hybrid Gadolinium Oxide Nanoparticles As Contrast Agents For Ct Imaging

X-rays that pass through the object, are captured behind the object by a detector. This detector can capture a 2D representation of all the object's internal structures. Contrast radiography is a type of contrast medium, that makes the structures of interest stand out visually from their background. So it gets rid of the blurs in the photo.

The mixture was heated at 120°C using an aluminum block and was stirred gently. After all of the solid dissolved, it was heated for 20 additional minutes to ensure the reaction was complete.

The reaction is carried out in saturated aqueous ammonium chloride solution. Thus no special drying of solvents, reagents, or glassware is required. The reaction mechanism for this experiment can be seen below (Fig. 2)

X-ray use for diagnosis – Describe example of the use of an X-ray for diagnosis including IMAGE

•Angiography- is an imaging technique also know as an x-ray. It visualize the inside of blood vessels and organs after injection of contrast material. A long flexible catheter is inserted through the bloodstream to deliver dye. That is what the contrast material

Computed Tomography imaging also known as CT or a CAT scan, combines a series of x-ray images taken from different angles and uses computer processing to create cross- sectional images also known as slices of the bones, blood vessels, and soft tissue inside the body. The CT scan reveals anatomic details of internal organs that cannot be seen on conventional x-rays. A motorized table moves the patient through a circular opening of the CT scanner known as the gantry which houses the x-ray tube. As the patient passes through the CT system, the x-rays rotates around the opening. A beam of x-rays exposes the patient as the table moves in and out of the scanner in a series of phases. Detectors on the opposite side of the patient record the x-rays exiting that section of the patients’ body. They then produce cross-sectional views or slices. The data is then sent to a computer to reconstruct all of the individual

The journal article "Radiation Protection in Computed Tomography imaging" wrote by Jason Bond, R.T. (R). Radiologic Technology published the article in July/August 2016. In the article, the author addressed radiation protection methods in Computed Tomography Imaging. The author believes best CT image and achieve ALARA, require proper competency of the radiologic technologists and personnel. The author highlighted the importance of proper training, be familiar with dose-saving features and staying competency in lower radiation dose. The author stated the importance of lower radiation dose in Computed Tomography Imaging by comparing the chest CT exposure dose to a routine chest radiograph. "A routine chest radiography, for example, delivers a dose of approximately 0.02 mSv to the patient, whereas a chest CT delivers a dose of approximately 8 mSv, a 400-fold increase between the 2 modalities (Bond, July/ August 2016)." The author using qualitative data support and summarized the effective methods of radiation protection methods in Computed Tomography Imaging. The author using the recent reference to back up his hypothesis, all reference was chosen is within five years. The author concluded, to achieve

Modern medical technology allows physicians to capture detailed images of the body for diagnosing and treatment planning of various health issues. Radiologists use imaging technologies to diagnose or treat diseases. Interventional radiology is the performance of medical procedures with the guidance of imaging technologies. Acquisition of medical imaging is usually performed by a radiologic technologist and the results are interpreted by Radiologists, medical doctors that specialize in radiology. While Magnetic Resonance Imaging (MRI) and Computed Tomography Scan (CT) are useful for diagnosing and treating illnesses, each has their own health risks and benefits.

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.

Computed tomography, commonly known as CT or CAT scan, is a painless, non-invasive diagnostic tool that uses a specialized form of X-ray coupled with computer technology to produce cross-sectional images (slices) of soft tissue, organs, bone and blood vessels in any area of your body.

Imaging technology is the visual representation of a body part, such as an organ, for the purpose of a medical diagnosis. Nowadays, technologies such as X-Rays, Magnetic Resonance Imaging (MRI) and ultrasound are used everyday for medical analysis. X-Rays are very useful because they can penetrate through different materials to give an image of the interior of the body. MRI use strong magnets to create an image of a body part, while ultrasound imaging uses sound waves.

Eighty million CT scans are done each year in the U.S. alone according to CBS news. CT stands for computed tomography. CT was founded by Sir Godfrey Hounsfield and Dr. Alan Cormack more than three decades ago. CT scans can show little tiny problems as small as a grain of rice in the human body. Advances in computed tomography (CT) scans have made it easier for doctors to clearly see what is wrong and where to start when a person is sick, injured or in pain. Computed tomography scans are one of the most common tests used in doctors’ offices and hospitals along with dental offices as well. With the many types of CT scans that can be done; Doctors can diagnosis hundreds of different problems and illnesses. They can show things in the human body like dental problems, different types of cancer such as lung and rectal cancer, and cardiac problems like coronary artery disease.

Computerized Tomography(CT) Scan: CT scans use a combination of x rays and computer technology to create three-dimensional (3-D) images. A CT scan may include the injection of a special dye, called contrast medium. CT scans require the person to lie on a table that slides into a tunnel-shaped device where the x rays are taken (National Institute of Diabetes and Digestive and Kidney Diseases, 2016).

When talking about medical technology the first thing that most people think of are the big pieces of machinery. The CT scan and the MRI are the two main machineries used to diagnose many different problems in patients. A CT or CAT scan is an x-ray like procedure that combines many different images from different points of view with the help of a computer to get a cross sectional view and even 3-D images of organs and bones (Stöppler, nd). A CT scan can be used to define
