How MRI Scans Work – Infographic

How MRI Scans Work – Infographic

Visualisations-in-Medicine-MRI Hi-Res

This infographic is about MRI scans work.  It also contains some information about the history of MRIs.  Usually, we try to break our reviews into subheadings, but this is a sort of free-flowing piece, so I’m just going to to with it.

MRI – Magnetic Resonance Imaging – used to take high quality pictures of the insides of humans.  It was invented in 1977 by a guy named Raymond Damadian.  A photograph of an MRI shows a technician, a patient, the machine itself, and the motorized table that slides the patient into the MRI Scanning tube.  Ooh.  We can do headings after all.  Here we go:

The Inner Workings of an MRI

The MRI Scanning Tube consists of a radio frequency transmitter and receiver that sends and receives radio signals, a main magnetic coil that creates a uniform magnetic field, and x, y, and z magnetic coils that create varying magnetic fields.  These are pointed out on a diagram of the MRI.

A Step by Step Guide

Since the human body is 60-70% water, and water is made up of hydrogen and oxygen, and hydrogen atoms have protons that spin naturally, the MRI works by creating a uniform magnetic field around the patient, causing his or her hydrogen protons to spin and align with the magnetic field.  The radio signal transmitter then sends out radio wave pulses of varying frequencies, and when the frequency matches the frequency of the spinning proton, the energy wave is absorbed by the proton, causing the proton to tilt out of alignment with the magnetic field.  The pulse ends, and the proton returns to the alignment of the magnetic field, and the leftover signal is picked up by the receiver.

The hydrogen protons in the human body emit different types of waves, depending on what and where they are.  The computer in the MRI can tell the difference between bone and blood, for example, and cancerous tissue emits a longer signal than non-cancerous tissue.  The computer matches up all the signals to the different parts of the body, and is able to detect when a signal is abnormal.  In a scan output, different colors mean there are differences in tissue type, and the MRI creates an image of the body using the location data and tissue type data.


MRIs are used to detect tumors, cysts, hemorrhages, torn ligaments, brain infections, and more.  Radio waves have less energy than X-rays, making them less harmful than X-rays or CT scans.


So far, nobody has proved that there can be any lasting health damage from an MRI.  In the past, before certain protocols were implemented, patients experienced  wounds related to unsecured metal objects in the room, or metal objects inside the patient, getting drawn into the magnetic field and causing injury.

Affluence and Travel

Affluence and Travel



This infographic is  about affluent people and how and where they travel.   I had no idea what an “HNWI” was, but looked further down the infographic and learned that “HNWIs” are “High Net Worth Individuals.”   Below, there is a map of the world with a key – HNWI’s are people who are worth more than a million dollars, and Ultra-HNWIs are people who are worth more than $30 million.  According to the map, these people reside in certain regions of the world, and the percentages mean the % of HNWI and Ultra-HWNIs in each country vs. the regular people.

The next section breaks down these high affluence people by country. The U.S. has the most rich people.  Unless you’re very familiar with the flags of different countries, you may not be able to sort out where the other rich people live.

Travel Trends

Here we go.  Now is the section where they talk about what the affluent people do on vacation.  From a poll of wealthy people, the top 5 trends were listed in this section, according to the creator of the infographic.  The percentage numbers represent the number of times the activity appeared in the top five choices.  Apparently, 63% of people engage in family and multi-generational travel, 41.3% go on luxury cruises (no word on how many go as families), 33.2% go on adventure trips, 22.1 go on guided tours, and 19.2% stay in beach resorts.

Use of Mobile Media

We’re then given some pie charts that talk about how many luxury travel bookings occur online (55%), how many HNWI use Facebook and other social media sites (they make social media all one word, and the number is 70%), and how many wealthy Americans download travel apps (it’s 40%).


The first map was where people lived, and now we get where they travel.  The map is broken down with bubbles that show where people go in summer and in winter, and there are no percentages.  We just see that Costa Rica, Argentina, Italy, England, Spain, Australia, and New Zealand are visited almost exclusively in summer, and Whistler, Colorado, Hawaii, Switzerland, Mauritius, Maldives, and Thailand are visited almost exclusively in winter.  The Caribbean, Mexico, France, and South Africa  are visited in summer and winter.

Luxury Travel Products

They then give us a list of the most expensive luxury travel products.  Most are given in US dollar amounts, but one is given Euros.  Did you know you could rent Necker Island (owned by Richard Branson) for $51,000 per day?

Design:  A

The infographic is visually attractive, the colors are nice, and the typeface is easy to read and pretty.  It’s an exciting concept, because we all like to think about what we’d do with tons and tons of money.

Information:  C

There are a few small typos and the information provided is not explicitly explained, but it is interesting information and  the social media section is good.  Plus, everyone likes to see how the other half lives.

Airbus A380 Extraordinary Facts Infographic

Airbus A380 Extraordinary Facts Infographic


Here is an Airbus A360 infographic that will send you reeling through the air like an out-of-control plane. Let’s open this analysis with the following question. Think American-based airline companies are good? B-b-baby, you ain’t seen nothing yet. American airline companies ain’t got nothing on Singapore. Why? Because of a little plane called the Airbus A380. Of course, this plane isn’t actually little at all. It’s the largest plane in the world. It can carry a monstrous 450 passengers.

The graphic notes a series of interesting facts about the plane, such as the fact that Sydney Airport Authorities spent $128 million to upgrade its infrastructure in order to accommodate the jumbo jet, which included the widening or runways, the building of special air bridges, and the reinforcement of underground tunnels. Alright, let’s get down and dirty with some nitty-gritty facts about the plane. The plane is 72.7 meters long (which is the size of two blue wales), and it is 24.1 meters high (which is equal to five giraffes). Qantas is adding 20 A380s to its fleet at a total cost of $6.7 billion. That is a whopping number. Just how whopping. Well, it’s three times the GDP of Greenland, which is equal to 13 ritzy Sydney Opera Houses. It has an 80 meter wingspan (equal to 35 wedge-tail eagles), and the thing weighs 580 tonnes, which is equivalent to 165 elephants, meaning that even the Incredible Hulk would probably have trouble lifting the plane. I imagine even he has a maximum capacity.

Oh, and how much cargo room is there in the plane? Enough for 3,000 suitcases, so if you fly on this baby, you don’t have to pack light. It is now time for the grading portion.

Infographics Scorecard

Design: B+

Pretty decent graphic, from a design standpoint. I am not that impressed with the color scheme. Seems pretty plain. Beyond that, the images were captivating.

Content: A-

A great research job here. The creators went out of their way to find intriguing facts. Showing, for instance, that the amount of paint required for the craft was equal to the amount of paint Michelangelo would need if he painted the Sistine Chapel 97 times over took some real research.

I applaud the Flight Centre for providing such a stupendous graphic.
