X-rays have both medicinal and non-medicinal uses. | In hospitals, x-rays are used to show the body structure and help to detect tumors and broken or fractured bones. They also have industrial uses such as scanning for weapons at airports and spotting imperfections to small for the human eye. Help stop diseases before it gets too late. | Very few health hazards.
A computerized axial tomography (CAT) scans internal organs, bones, soft tissue, and blood vessels, which provides a better clarity and shows more detail than an x-ray does. A magnetic resonance imaging (MRI) uses magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bones, and all other internal body structures. MRIs do not use ionizing radiation, which is what x-ray stands for. Ultrasound imaging is a procedure that uses high frequency sound waves to produce dynamic images of organs, tissues, or blood flow inside the body. Radiologist technologist are very important to the society because with the knowledge of taking the x-rays, MRIs, CAT scans, and Ultrasounds we can help in the diagnosis process.
MAGNETIC RESONANCE IMAGING PROCEDURE The world of medical imaging was still becoming accustomed to CT scan and ultrasound when a new way of imaging by using magnets and magnetic fields was invented. Some medical professionals wondered why they needed another test; radiologists and technicians were still trying to get used to the tests they had. But, the images produced by MRI were so spectacular, especially in areas that physicians could barely see before, like the knee, the shoulder, and other areas. Pictures of the brain, neck, and lower back were now visible from three different planes (axial, sagittal, coronal), as compared to the one (axial) that CT scan provided. There was no radiation and no serious side effects.
It can actually heat the lead used in the older models. This could cause cardiac tissue damage in patients. The lead acts as a conductor to the radio frequency energy. The studies have shown a wide range in heating after an MRI. (Ahmed, et al., 2013) The gradient magnetic field comes about by the actual process of the MRI.
This medical field is referred to as Sonography. Ultrasound uses sound (sonic) waves to capture images of the internal organs and tissues for the diagnosis and treatment of medical problems inside human beings. The Sonographer takes readings of the appropriate areas and angles that the physician had requested, and then sends the information back for interpretation. Unlike other diagnostic imagining system’s that use radiation, ultrasound is completely radiation free and is safe for both patients and ultrasound technicians. Knowing this little bit of information I’m sure questions are flaring up in your mind wondering what else Sonography has to offer for patients, and if still interested in learning more continue reading as for my facts about ultrasound will have your minds amazed about how technology has changed over the years and how it lets
What imaging technology would best reveal the location and extent of damage to Tim’s brain produced by his stroke, and why? Magnetic Resonance Imaging (MRImay) prove to be helpful here as; it is a modern, noninvasive diagnostic tool which is able to provide a high level of anatomic details so that, stroke can be located and the extent of damage could be determined. MRI is specifically preferred because of its sensitivity as; the images produced by it can
Most diagnostic tests conducted in a Radiology Department expose patients using ionising radiation that are considered to be generally safe. There is no doubt that any radiation dose implicated could produce some form of effects on such individual. Hence, the purpose of radiation protection and safety programmes aim to prevent such unnecessary radiation exposures and to control the amount of exposure dose whenever is required. Even though it is necessary to reap the benefits on the use of radiation in the diagnosis of certain illnesses, it is still imperative to maintain the level of dosage to be at its minimum. This helps in reducing the patient’s lifetime risk of developing cancer while undergoing the different types of x-ray examinations.
Expert systems are used to close the gap in knowledge providing effective, efficient, and accurate care. MRI and CT machines have the capability to capture images of a patient’s body part without someone controlling the
Previously, a form of refractive surgery called photorefractive keratectomy (PRK) was performed. In the procedure, a part of the cornea was removed with a laser, as a means to decrease a near-sighted person’s dependence on glasses. It was a highly successful procedure; however, the patient would have to go through long recovery periods and it was common to need a second corrective procedure. Then, laser assisted in situ keratomileusis or LASIK eye surgery was introduced as a newer refractive surgery. Compared to PRK, it could serve a greater amount of people, as it corrects the vision of those with myopia (near-sightedness), hyperopia (far-sightedness), and astigmatism, but without the longer healing period.
Once the orbital apex and cavernous sinus get involved, clinical signs become obvious. Imaging techniques, like CT and MRI, are useful in detecting the extent of orbital spread but not sufficient for a definitive diagnosis in patients without clinical signs of proptosis or eye movement limitation. The tumor histology is for planning the surgery, as exenteration of the orbit may not be necessary in some cases of esthesioneuroblastoma, adenocarcinoma, adenocystic low-grade carcinoma or squamous cell
