The first full body scanner arrives to change the tomography in real time and is up to 40 times less invasive



Most major investigations do not rise overnight. That is the case of EXPLORER, the first full-time medical scanner capable of holding up to three dimensional images. Simon Cherry and Ramsey Badawi, scientists at the University of California in Davis, have successfully qualified this positron emitting tomography or PET, for her acronym in English.

The initial idea came to an end in 2011, with a 1.5 million dollar grant from the National Cancer Against Cancer, but later in 2015 the money was expanded with an additional 15.5 million from the NIH. At the end of November 2018 he was able to show the first images with his full body scanner and It is expected that it will be extended to some hospitals in Sacramento in the spring of 2019.

Faster, less intrusive full body scanner

Using the positron emission tomography and X-ray computer thomography (CT), this machine can produce images in just one second. Some images that show features that are not usually found in normal PET scanners. The EXPLORER is 40 times faster and allows you to produce Complete a whole body diagnostic scan in about 20 or 30 seconds.

With this scanner, creators make it possible to improve the monitoring of the metabolism and the exception of many substances. Also how some medicines affect the whole body. There is a strong example of this to be seen in the Distribution of radio-labeling (fluorodeoxyglucose) sugar across the body. The substance is sprayed into the body and thanks to the EXPLORER that can be seen in real time how sugar travels to the heart and is distributed through the arteries. Not only that, after a few minutes, you can see which part of the substance travels from the kidneys to the bladder and that stays in the heart or brain.

As well as offering very attractive images, the scanner would also get radiation dose up to 40 times lower than standard PET. This opens the door to new studies that have so far been rejected too overwhelmingly. For example, repetitive tomography can be performed on the same patient or in pediatric studies where the radiation of which children are exposed is more comprehensive.

Three-dimensional scanner

Together with the United Imaging Healthcare (UIH) department in Shanghai, both scientists have developed this scanner based on a platform that can be exported to other health markets that offer them hospitals or other research centers. In terms of Simon Cherry:

I do not think it will be long before we see several EXPLORER systems around the world. But that depends on showing the benefits of the system, both clinically and for research. Now, our focus is on planning studies that will show how EXPLORER will benefit from our patients and contribute to our knowledge of the whole human body in terms of health and disease.

The applications of this full body tomographer scanner are very varied. As well as offering 3D images in a shorter period, it can also be used trace medication after marked and analyze how they are distributed through the body, improve diagnosis of some diseases by managing how the disease is going on and using to investigate new drugs.
