The magnetic resonance imaging (MRI) machines in hospitals are great at creating pictures of the human body. For decades, scientists have hoped that the same technology could be used to examine much smaller things, like individual molecules. Now, a team from Canada and the United States has revealed a new,…
MRI machines use a powerful magnetic field to produce internal images of the human body. The magnetic fields are so powerful that hospitals take great care to ensure no iron-containing metals come near the machines while they are in use. In rare cases, however, mistakes happen. This past weekend, an Indian man…
Using strong magnetic fields and radio waves, magnetic resonance imaging (MRI) machines let us peer inside the human body as if it were sliced into thousands of layers. The same effect has been achieved here, letting you fly through the massive Sofa Hotel in Istanbul. But do they make MRI machines that big?
Schizophrenia is a mysterious, misunderstood mental illness without a full cure. However, researchers from the United Kingdom and China may have found a clue that could help to understand it better.
For a never-before-seen look at how an opera singer is able to produce such an amazing sound, German baritone Michael Volle performed Song to the Evening Star from Wagner’s Tannhäuser during an MRI scan. The technique uses magnetic fields and radio waves to see right through the human body, and is able to capture…
MIT neuroscientist Rebecca Saxe captured this stunning MRI image of herself and her child inside a 3 Tesla magnetic resonance imaging scanner, creating an emotionally striking yet abstract work of art.
Among many other things, General Electric makes the MRI machines that peek inside your body when something’s broke. To do so requires one very cold, very big magnet.
Physicists have created a wormhole device that can tunnel a magnetic field through space. It sounds like Star Trek, but we won’t be zapping humans across the universe anytime soon. Still, the breakthrough could revolutionize certain magnet-based technologies, including MRIs.
You already know that a penis has arteries to bring blood to its erectile tissues, and veins that take the blood away again when it returns to its normal flaccid state. You may not know that there’s another set of vessels tucked under its skin. We just got our first good look at them.
Hey! What are your plans for that artichoke you’ve got there? You’re going to grill it and serve it with some lemon-butter sauce? That’s cool. We’re just going to stick ours in this MRI machine here.
One of science fiction’s biggest unfulfilled promises are medical nanobots: tiny little machines that will run around your body, repairing what’s gone wrong. Scientists from the University of Houston are setting out to change all of that, with an incredibly clever self-assembling robotic gun that can clear blockages…
Researchers raise alarms about unknown health risks of GE’s Omniscan and Bayer’s Magnevist, drugs injected to get better MRI pictures that contain the heavy metal gadolinium.
Diagnosis is hard. Especially when it comes to joint injuries. Doctors can make educated guesses based on your symptoms, to be really sure, they’ve got to look inside. While MRI is the most popular option, it’s expensive, time-consuming, and not particularly accurate. That’s why this new, miniaturized camera that can…
When magnetic resonance imaging (MRI) scanners reach the end of their lifetime, hospitals have to deal with a large piece of electronic waste, stuffed with potentially dangerous parts. Unless a physics lab can make use of them.
It’s a remarkable technology capable of looking inside a human being, but magnetic resonance imaging—or MRI—machines are finicky and require a patient to remain absolutely still while it does its thing. But researchers at the University of Illinois have found a way to capture up to 100 frames per second on an MRI…
It's one of the most addictive things humans can do. Everyone does it. And it feels so good when you get to do it. We're talking about cracking your joints. Researchers have alway been curious as to where the sound of joints cracking comes from and put a hand under MRI to find out (and for us to see visualized in real…
Siemens’ latest MRI machine (MaÂgneÂtom PrisÂma Tim+Dot SysÂtem 3 TesÂla) is one of the most powerful, state of the art medical imaging devices in the marketplace. The first Magnetom Prisma 3-tesla MRI units was installed in the USA at the University of Minnesota a year ago. Now there are about 50 units in Europe, and…
A little-known and harmless side effect of MRIs gives us an intriguing way to murder people. Tricking them into getting an MRI would be tough, but afterwards? It's almost too easy.
Here's an odd by-product of body art. In an MRI machine, a tattoo can start generating heat to the point where it burns your skin.
Neuroscientists from the University of Geneva have devised a technique that reveals evidence of cognitive decline prior to the onset of symptoms — an indication that deterioration in the brain happens before we're able to pick up on cognitive deficiencies.
