We live in a world where everything is changing and moving
really fast. Not knowing whether that change is for the better or for the
worst. Innovation in medicine and health care is one of those changes that is
for the better. These discoveries have helped save millions of people lives,
have stopped thousand of diseases to spread and also nowadays one can make more
accurate diagnosis about different symptoms one can have. Some of the
innovations we are going to mention further on are the functional magnetic
resonance imaging, laser surgeries, the artificial heart, and the usage of
nanoparticles.

Firstly we have the functional magnetic resonance imaging
(fMRI) measures brain activity by detecting changes associated with blood flow.
So when an area of the brain is in use, the blood flow to that region also
increases. This device has taken a great usage these past years also because it
doesn’t involve the individual in any kind of danger such as that of radiation.
 The only risk there is for people who
are claustrophobic and also it isn’t good for pregnant women to go on with the
process. The magnetic resonance can be used to monitor brain tumor growth,
diagnoses of Alzheimer’s disease or even to find out where in the brain the
seizures are originating.

Secondly there is laser surgery which was firstly used in
surgery in 1987. This is a type of surgery that uses laser to cut tissues. It
is mostly used in eye surgeries, but in the last years it also has a very wide
usage on different parts. Some of the other applications are dermatology and
plastic surgery, endovascular surgery, foot and ankle surgery, spine surgery
and so on.

We continue on with the artificial heart. This was invented
by Robert Jarvik in 1982. This device is a replacement for the heart. Obviously
this has a high benefit which is to lower the need of a heart transplant. Due
to this discovery millions of peoples live have been saved through the years.

And the last innovation we are talking about is the usage of
nanoparticles. This is mostly an experiment made from Rutgers University. This
experiment was made by a group of scientists which took a mouse model of human
breast cancer and injecting the animals with nanoprobes, which are tiny optical
devices that use X-rays to identify micro metastases. The nanoprobes are
carried along by the bloodstream, allowing the researchers to get a quick and
reliable image of the location of affected cells in the body.  They also say that these nanoprobes are
faster than the magnetic resonance and also way more efficient than them.
Because not only do they notice the tumor earlier, but also they notice it in
its earlier stages something that has never been done before. This is a really
efficient discovery that will save many more lives.

These new discoveries have great benefits and also they have
saved millions and thousands of lives. We have to admit that medicine is
changing and this is for the better. This way we can rest assured that the
future will be brighter and safe.
