Radioactive Isotopes Radioactive isotopes are any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha‚ beta‚ and gamma rays. Every chemical element has one or more radioactive isotopes. More than 1‚000 radioactive isotopes of the various elements are known.. Approximately 50 of the isotopes are found in nature; the rest are produced artificially as the direct products

standard for diagnosing sinusitis‚ for clinical research‚ is through sinus aspiration and culture. Among those pt’s who were thought to have sinusitis‚ only 50% actually had the disease based on sinus aspirates. For general practice‚ the use of radiography through the use of sinus x-rays‚ CT‚ or ultrasound‚ will correctly classify 4 of 5 pts correctly. This has become the reference standard for primary care. This as well as the pt’s symptoms are used to diagnose acute bacterial sinusitis. There

ALL YOU WANTED TO KNOW ABOUT CBCT CBCT is a useful tool for imaging the craniofacial area that produces more realistic images that facilitate interpretation. All the previous conventional and digital intraoral and extraoral procedures‚ as they were two dimensional (2D) projections‚ suffer from several limitations. These limitations were magnification‚ distortion‚ superimposition and misrepresentation of structures. CBCT has achieved a transition of dental imaging from 2D to 3D images. Moreover

My experience while job shadowing radiologic technologists was very enjoyable‚ and made me want to pursue the career path even more. I noticed that there was rarely ever any down time‚ technologists were taking images or filing out patient charts on the computers. When things get very busy there are radiologists and technologists going in every direction. A few examples are; going to the emergency room‚ patient rooms‚ imaging rooms‚ different plazas‚ and operating rooms. All of the technologists

common arterial blood gas finding. Hypocapnia and respiratory alkalosis may occur due to the high respiratory rate of an acute asthma exacerbation‚ but prolonged or severe symptoms may cause hypercapnia and metabolic acidosis (Karwat‚ 2002). Chest radiography is often normal; however‚ findings can encounter hyperinflation of the lungs with flattened diaphragm if there is obvious air trapping with the diagnosis of asthma. A CXR may be obtained if the reason of the patient’s wheezing is uncertain. This

The Sanger Method was developed by Frederic Sanger. It was the first method developed to sequence the genome and the genetic code and is still the most commonly used method of DNA sequencing. In 1980 Sanger was awarded a nobel prize in chemistry for his work concerning DNA sequencing along with Paul Berg and Walter Gilbert who also contribuated in this major breakthrough. Since then the Dideoxy chain termination method has been highly developed and optimised. To sequence DNA in term of the Sanger
