Relevance to biology (PET Scan) Today‚ most PET scans are performed on instruments that are combined PET and CT scanners. The combined PET/CT scans provide images that pinpoint the location of abnormal metabolic activity within the body. The combined scans have been shown to provide more accurate diagnoses than the two scans performed separately. Nuclear medicine is a branch of medical imaging. It uses small amounts of radioactive material to diagnose and determine the severity of various types

Last week‚ we have given the opportunity to take tour in the Davao Doctors Hospital to see the Specializations in Radiologic Technology such as Magnetic Resonance Imaging‚ Computed Tomography‚ Nuclear Medicine and etc. After seeing the different modalities‚ I felt happy because it is my first time to take a look and encounter any kinds of machine. Before‚ I was expecting that being a radiologic technologist is a hard job. But then when I had given the chance to see and know what their works are

Cocker and Walton Prizes 2012 Physics in Medicine By Fayaz Rahaman ➢ Introduction Physics is about understanding the laws that govern the world around us. Most people know about the problems solved and the discoveries made by physicists in the past‚ such as the orbits of planets found by Galileo‚ the law of gravity first unravelled by Newton and later extended by Einstein. It is not as widely

Practical 1 Title: Tissue Processing Aim: To examine human cell and tissue under the microscope Introduction: Tissues from the body taken for analysis of diseases must be processed in the histology laboratory to produce microscopic slides that are viewed under the microscope. These tissues are usually fixed into paraffin. Microscopic analysis of cells and tissues requires the preparation of very thin‚ high quality sections mounted on glass slides and properly stained to demonstrate normal and abnormal

X rays and Ultrasound are two of the main imaging techniques used in radiography. For the purposes of this essay‚ we will look at conventional x-rays and diagnostic ultrasound. Conventional x rays are non-invasive diagnostic techniques that are used to capture images of the body’s organs and bones. Diagnostic ultrasounds are high frequency sound waves to create an image of soft issues in the body such as muscles‚ joints‚ and internal organs. As examined below‚ while both are used in diagnostic radiography

Methods of studying cortical specialisation are divided into two groups: the invasive‚ and the non-invasive. The invasive methods are those‚ in which something is injected into the brain‚ to find out what the problem is. The non-invasive methods are more ethical‚ as there are no changes in the brain area‚ therefore no damage can be done to it. One of the invasive methods of cortical specialisation is neurosurgery. It involves manipulating with the structures within the brain. There are two main
