OOn Monday, scientists revealed the first human images inside the world's most new body scanner, of the EXPLORER name. The name is correct because this scanner is completely left nothing to the imagination, tracking the way in which drugs and diseases move through each beer and crannog in the body.
Designed by biomedical engineering teacher Simon Cherry, Ph.D., and biologist Ramsey Badawi, Ph.D. At the University of California, Davis, this scanner produces images that appear like a hybrid between a PET scan (often used to find tumors) and a X-ray, all black and black. White. But what's interesting about EXPLORER, which will be officially unveiled at the North American Radiological Association meeting on November 24th, is that it does not produce detailed images of tissues or bones. Cherry says Contrary It can also create 3D movies that show where some drugs can end in the body.
We see this in the video at the top of this article, showing the first images of the scanner, taken at Zhongshan Hospital in Shanghai. In the video, Cherry calls a "dynamic film," the subject is having a leg injection of F-18 fluorodeoxyglucos. Only sugar has to tag with a fluorescent mark, which allows EXPLORER to be traced as it is transported from the legs to the heart and beyond.
"You can see it [glucose] going through a vein in the leg, traveling to the heart when it is then pumped into the lungs that appear after a few seconds, "said Cherry." Then he goes back to the heart and it is distributed through the arteries that reach all the tissues in the body. "
About the fifth in the video, you can see the fluorescent glucose white light goes into the heart and then explode – which is powered by pumping & # 39 ; r heart – to the brain, the lungs and a variety of tissues. Over time, Cherry adds, glucose accumulates in tissues such as the brain, liver and kidneys. The scanner gives us the chance to see what those tissues do with the substance once it's there – that is the process we know as a metabolism. It also reveals more detailed details of human existence, such as kidneys wandering to the bladder, about 16 seconds.
At the end, Cherry adds, the scanner can produce a 3D map of the whole body in 20 to 30 seconds.
"So, at the end of the video, you see a classification that shows glucose metabolism in the body, and you can see high metabolism in the brain, heart and liver," he added.
This scanner can help to expect one of the main challenges [drug delivery](https://www.nibib.nih.gov/science-education/science-topics/drug-delivery-systems-getting-drugs-their-targets-controlled-manner. When you donate a & # The human body, it ends in a number of places, some of which are unintentional. This scanner can help drug supply researchers make more drugs targeted. take fewer shortcomings on the way to the last destination.
The team intend to bring one of these scanners to Sacramento, where they hope it will be operational by 2019. As it is very expensive to act, says Cherry, he will be the cost must come down before its use becomes wide. But being an unprecedented instrument giving us an eye to the human body, it could have many uses that we have not even thought again.
"This is the first in the world," said Cherry. "It may also be that new research on this scanner will be possible because it can see the whole body at once, leading to new clinical applications," he said.
