Medical imaging is the technique and process of creating visual representations of the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues ( physiology ). PET Scan ( Positron Emission Tomography Scan) A PET scan creates 3D images of the body, it does so by using Radioactive tracers which are administered to a patient through intravenous injection. The tracers are made up of molecules that are tightly bonded to radioactive atom called an isotope.   These carrier molecule interact with the specific proteins or sugars inside patient’s body. The carrier molecules that will be used totally depend on what the doctor is looking for. If she suspects growth of cancer tissue, she may use FDG , a modified form of glucose. When tissues absorb a lot of glucose, it may indicate a growth of cancerous tumour. The isotope produces small partic...

3D printed body parts Driverless cars, artificial intelligence, smart watches – the future is truly upon us. With science and technology developing so quickly, medical breakthroughs continue to be made every day around the world. But what are some of the most profound advancements in recent years and how can they change the way we treat medical conditions? Here is one of the amazing advancement in medical science that has blown my mind completely. 3D printing is widely regarded as being industry-changing technology when it comes to consumer goods and manufacturing. But what’s not widely known is that scientists have successfully created human body parts using 3D printers. The team at Wake Forest Baptist Medical Centre developed a new technique that 3D-prints a tissue riddled with micro-channels, rather like a sponge, to allow nutrients to penetrate the tissue. The Integrated Tissue and Organ Printing System - or Itop - combines a bio-degradeable plastic which gives the struc...
