Medical Technologies Transforming Disease Prevention, Diagnosis And Treatment

Advances in medical technology are transforming healthcare. There has been an explosion of new technologies emerging in recent decades that have the potential to improve the prevention, diagnosis and treatment of disease. These include immunotherapy drugs, imaging technology, wearable health-monitoring devices and genome sequencing. This article will discuss these four technologies.

Imaging technology

Medical imaging is the process of creating pictures of the inside of the human body. These images are used to diagnose diseases and treat patients. There are many different types of imaging, such as X-rays, CT Scan (computed tomography) scans, MRI (magnetic resonance imaging), ultrasound and Positron Emission Tomography (PET). These imaging techniques can show structures inside your body in great detail.

• X-ray: use, guess what, X-rays to create images of bones, certain types of tumours and other forms of dense matter.
• CT Scans: use multiple X-rays for producing cross-sectional layers, which reveal detailed images of parts inside the body, including organs, tissues, bones and tumours.
• MRI: use radio waves and magnetic fields to show detailed images of soft tissues, organs, bones, cartilage and ligaments.
• Ultrasound: involves high-frequency sound waves to produce moving images on a screen that shows organs, bones, soft tissues, and a fetus inside the body.
• PET: involves injecting, swallowing or inhaling a type of radioactive ‘tracer’. A scanner can use gamma rays emitted by the tracer material to show images of organs and bones.

Imaging technologies can help doctors identify potential health issues before they occur—or even spot them after they happen but before they become problematic enough to cause symptoms like pain or loss of mobility. For example, ultrasounds can detect early breast cancer when mammograms won’t; MRIs can detect aneurysms (blood vessel bulges) inside the brain, and CT scans allow doctors to see detailed images within specific regions inside someone’s body without first having them undergo invasive surgery.

Radiology technicians or imaging technologists are health professionals trained to use specific imaging types, such as radiographers for X-rays or sonographers for ultrasound imaging.

Wearable health-monitoring device

A wearable health-monitoring device is a small, portable device that measures and analyses physiological data. Though they have been around for several years, wearable health-monitoring devices are becoming increasingly popular due to their ability to provide real-time data on various aspects of human health.

There are many different kinds of wearable health-monitoring devices available today; let’s look at a few.

• Activity trackers are designed to measure physical activity and movement patterns throughout the day. These devices can be worn as watches or bracelets and track daily steps and other variables such as calories burned or heart rate variability (HRV).
• Sleep monitors typically consist of a headband or cap that measures brain waves during sleep cycles to determine when you’re asleep versus awake. They also monitor your heart rate so that they can calculate how long each cycle lasts based on those two measurements alone without requiring any additional hardware like An electroencephalogram (EEG) machine would require. It’s essential for users who wear these sleep monitors at night since an actigraphy may not accurately account for all hours spent awake at night due to some limitations in how motion sensors capture motion patterns during deep sleep periods.

Genome sequencing

Genome sequencing is the process of determining the complete DNA sequence of an organism. The genome comprises an organism’s genes, regulatory regions and non-coding DNA sequences. For example, in humans, the genome consists of about 3 billion base pairs and represents around two per cent of total cellular DNA.

An article by Martin Carkett and Alexander Honkala – titled: What is Genomic Sequencing and Why Does it Matter for the Future of Health? 22 Feb 2022 describes a genome as the complete set of DNA sequences in an organism and contains all of the instructions required for that organism to function, including embryogenesis, growth, responding to the environment, and healing from disease. The Human Genome – the complete map of all 23 large DNA sequences (chromosomes) that encode our species – comprises around 3 billion base pairs within the nuclei of each of our cells.

While this sequence of base pairs is virtually identical in every human, differentiating us from, say, a chimpanzee or a mouse, subtle differences in each of our genomes make us unique. Whole-genome sequencing, pioneered by the Human Genome Project, enables us to read a person’s genome and, among other things, identify differences from the average human genome. Such differences (mutations) are often associated with disorders and diseases. Still, they can also be related to other factors like disease resistance or sensitivity to an environmental perturbation like sunlight or exercise.

Genome sequencing has become a significant application in molecular biology research and medicine because it can be used to study evolution, disease and medicine. It also enables the diagnosis of genetic disorders such as cystic fibrosis.

Immunotherapy drug

Immunotherapy is a treatment that uses the immune system to attack cancer cells. It’s a relatively new treatment, but it can treat many types of cancer.

Immunotherapy drugs work by stimulating your natural defences against disease. In this case, they help your body’s immune system recognise and destroy cancer cells. That way, you don’t have to undergo surgery or radiation therapy to eliminate the disease from your body!

Immunotherapy has proven to be a promising method for treating cancer. Still, it wasn’t until recently that researchers identified the specific genetic factors driving certain cancers. In addition, advances in genomic sequencing technology are helping researchers better understand how cancer cells develop resistance to immunotherapies. These technologies provide new ways for developing more effective treatment options for patients with rare diseases and cancers—such as those who have failed previous treatment attempts or have shown signs of recurrence after surgery or chemotherapy.

Conclusion

These four technologies are poised to transform healthcare. The next few years will be an exciting time to watch as they make their way into clinical practice or become better entrenched with immunotherapy drugs and imaging technology already available. Wearable health-monitoring devices could help us monitor even more health metrics. Genome sequencing has been a game-changer for cancer treatment, but it’s still in its infancy to other diseases like Alzheimer’s or Type 1 diabetes – we’re only just beginning! In the meantime, we’re excited about these breakthroughs and looking forward to seeing what comes next from each field.
