Biotech Flashcards
What is medical imaging?
It is a test or diagnosis that doesn’t require invasive surgery, to diagnose or treat abnormalities in tissues, organs, and organ systems.
What are 6 different examples of medical imaging tech?
X-rays Ultrasounds Fluoroscopy (liquid + x-ray) Microscopy (taking a small sample and examining) CAT scans MRIs
How does an X-ray work?
It bombards the patient with x-rays, after which only dense tissue will show up on the radiograph. So only bones and dense tissues show up, giving a clear view of fractures and bone cancer.
What is fluoroscopy?
A type of x-ray where the patient is injected or ingests a fluid that shows up on the X-ray. It shows movement and positioning of organs, because it uses a continuous beam.
What is an ultrasound?
It is an imaging tech that uses high frequency sound to visualize muscles, tendons, and internal organs.
What is a CAT scan?
It is a special type of X-ray in which they use multiple cross-sections to make a 3D model/image of any part of the body. It shows internal organs, and is the preferred method of diagnosing cancer, strokes, kidney failure, etc.
What is an MRI and how does it work?
It uses a powerful magnetic field to align hydrogen in the body and release it, making the hydrogen release energy. Then the computer interprets this energy and constructs an image.
What is nuclear medicine?
Using a medicine that you take, radioisotopes get absorbed into certain tissues, showing up on camera or being processed by a computer.
What are biophotonics?
🐍 up yo butt.
cameras that are inserted into orifices and used to actually SEE the problem
What is microscopy?
Taking a small sample of tissue or cells and studying them under a microscope for abnormalities. It has allowed biologists to diagnose strep throat, STDs, and others.
What is biotech?
Any technological application that the biological systems of living organisms, to make or modify products of processes for a specific use.
What is an organ transplant?
Taking an organ from a donor, and giving it to someone else who needs it. Most organs come from people who have died, who have been harvested. (HARVESTED… yeesh…)
What are the two organs that you can donate without being dead?
The liver and one of your kidneys.
What is gene therapy?
Replacing an absent or faulty gene with a normal one. Biologists use a modified virus to carry the gene in and replace it. This is currently being trial tested on certain hereditary genetic diseases.
What is cloning?
Creating a genetically identical copy of a cell, tissue, or organism.
