Importance of Various Technologies

Technology in health care is always improving, and helps scientists get a better look as to what’s inside the human body.

Magnetic Resonance Imaging

            The digestive system is a complex body system, and scientists use an MRI to help diagnose and treat medical conditions. Dr. Raymond Damadian constructed a machine which scans the body with the use of magnets. MRI uses a powerful magnetic field, radio frequency pulses, and a computer which produces images of all the internal body structures. Doctors use the magnetic resonance imaging (MRI) to help diagnose multiple sclerosis, brain tumours, torn ligaments, tendonitis, cancer, strokes, etc. Alternatives include CT Scans and ultrasounds.

CT Scan
            The Positron Emission Tomography (PET) is a powerful imaging technique which diagnosis’s and treats many diseases, such as cancer. By using the PET scans, doctors are able to get an accurate image of the cellular function of the human body.

            Another example of an imaging system would be medical cameras which are developed for endoscopic applications. Endoscopy refers to looking inside the body for medical reasons using an endoscope. An endoscope is a long slender medical instrument which is used for examining the internal body and performing minor surgeries. This instrument is used to examine the interior of an organ. They are directly inserted into the organ. Images of the inside of the patient’s body can be seen on a screen. The entire endoscopy is recorded for the doctors to refer to in the future.

            Frederick Banting, a Canadian scientist is widely known for his role in discovering insulin. Before the knowledge about insulin was that it controls the metabolism of sugar, and without it, there would be an accumulation of sugar. Patients could not receive insulin because it was always destroyed by proteolytic enzyme of the pancreas. The question was, how would scientists extract insulin from the pancreas before it was destroyed? Banting read a medical article in a magazine about diabetes which inspired him to do research, which lead to a final experiment where a boy who had severe diabetes was treated with insulin, and his sugar levels then decreased. Today, insulin helps the lives of millions of people who suffer diabetes. 

A modern Canadian health research breakthrough is lab-grown blood. Scientists at McMaster University in Ontario have discovered a way to transform a person’s skin cells into blood. The technique could be crucial in the lifesaving for leukemia sufferers who are unable to find a bone-marrow donor. Since the new blood comes from the person directly, there is no risk of rejection.

These technologies are vital to health care in regards to research, diagnosis, surgery, etc. They allow doctors to get accurate knowledge of what is happening in the body and there will be advances in medicine which will help us find cures for cancers and diseases. Technology makes life easier for people, gives us an understanding of our own bodies, and teaches us how we can have a more prosperous, healthy life.

    Hi Caitlin!
    I enjoyed reading your blog! The information you provided was relative and I found your facts on MRI imaging and insulin very interesting and thought you explained it well. I agree with your statement that technology is important and helps in diagnoses because it allows doctors more access to information that they consider when making a diagnosis then to treat. Ford has come up with cars that are able to park themselves (park assist), if we've come this far with cars, who knows where we will go with technology in medicine, pretty far I think.

    Hey caitlin!
    Your blog was very informative and i found your information on The Positron Emission Tomography (PET) very interesting. I had no idea that this machine helps in the treatment of cancer! I also never knew that you could transfer someones skin cells into blood but theyre doing in at McMaster University! This could be used to treat leukemia? Thats amazing how many technological advances were making in the medical industry especially towards the treatment of different cancers. I agree with your statement "These technologies are vital to health care in regards to research, diagnosis, surgery, etc." Without these vital technologies we wouldn't be able to understand very much pertaining to the internal body systems. Technology is saving lives everyday due to certain peoples (even Canadians)significant contributions to our health care.

    Hey Caitlin!
    I really liked reading your blog! I thought the information was very insightful and informative. By reading yours, and other blog posts about medical technology used on humans, I understand more and more how medical professionals have to know these inventions and be able to use them. I realize how advanced these people's mind have to be about the technology they are using because they can save lives. For example, with the Positron Emission Tomography (PET). I find it so interesting that one big machine can produce images of the cell function in human bodies. Also, something I thought was very interesting, and that i haven't read in any other blog was the lab-grown blood. I did not know that it was discovered in Ontario, and that it could help leukemia patients have hope of being cured. I find it fascinating how helpful technology is in our lives.

    Your blogs are always informative, interesting, and fun to read! Your information is clear but not boring, your pictures add to the blog, your opinion is well thought out and overall it was an enjoyable blog to read. I have to admit although we often hear terms like MRI, CT scan, Insulin, etc. I don't know what they mean, what the purpose of these machines and scans even are. Your blog definitely told me. I was very interested to know that an MRI is able to detect and help diagnose Multiple Sclerosis because I explored this illness in my blog also. The Positron Emission Tomography Scan (that is a mouthful!)sounds like an extremely helpful, useful, and good instrument because it is not very invasive but still very detailed. Also, I really like how you added the part about McMaster University having a medical break through with creating blood because we need to all remember medical advancements must continue to be made, it cannot be over yet!
    This was a really excellent blog!

    Your blog was very informative and it reminded me of how advanced our medical technology was. I had always heart of PET and MRIs but never could tell the difference between them. I really liked the fact where there is research which could lead to new treatment options of leukemia patients. I can't imagine how someone could turn skin cells into blood but the idea of it sounds astonishing. Also I never knew that McMaster had medical break throughs which makes me even more happy that i will be attending there in university. GREAT BLOG!!

    Your blog is very insightful. It just proves how far technology has come in the last 100 years. With the CT scan for example, we wouldn't be able to test for diseases. That machine alone is so important that if we didn't have it, life would be much different. McMaster medical program is right up there with any other school in the world and their making strides to help the world. It just goes to show that our generation is the future. Great blog,
