Google algorithm proves extremely useful in cancer study

If you’ve ever had a problem with some of Google’s frivolity, it’ll all be forgiven after hearing this: researchers have used Google’s webpage algorithm to find cancer biomarkers, which can lead to early diagnosis and better treatment.

Google algorithm proves extremely useful in cancer study

Recently, researchers at Germany’s Dresden University of Technology ranked about 20,000 proteins by genetic relevance to the progression of pancreatic cancer and found seven that can help them diagnose the aggressiveness of each individual case. This leads to more effective and personalized treatment.

These biomarkers were found by employing the Google webpage algorithm, which Google uses to decide in which order to present your search results. The algorithm is complex and involves many factors, but one key factor is the amount of interconnectivity a page has. A webpage with no other pages linking to it and no social media interaction seems less important to Google.

In that vein, researchers helped narrow their protein rankings by looking at the network of physical and regulatory interactions to find which ones played a large role in the progression of cancer itself. The exact same way Google figures out which cute kitten blog to show you when you search “cute kitten blog.”

“Once we added the network information in our analysis, our biomarkers became more reproducible,” said Christof Winter, the paper’s first author.

Time will tell if this advancement has any major impact on cancer treatment, but it certainly has a load of potential.

MRI technology helps map human brain

BERKELEY, Calif. (KGO) — Researchers at the University of California are using a breakthrough technology to look at the human brain. It’s a new type of MRI and its producing images at speeds never before thought possible.

If MRI machines had wings, UC Berkeley physicist David Feinberg, Ph.D., would probably be crashing the sound barrier. As it is, he is creating images of the brain at speeds up to 30 times faster than even the most advanced research MRIs.

“When we made the first images, it was unbelievably fast,” said Feinberg. “That’s the scan, because the images are obtained simultaneously.”

He says the acceleration is the result of a breakthrough devised in a collaboration led by the University of Minnesota. It combines multiple radio frequency pulses to image different parts of the brain simultaneously. The signals are separated out by multiple receivers which measure the location and timing, producing a much faster scan.

“We used to be able to scan the brain the very fastest, with the echoplane imaging, in two to three seconds and now we’re able to image in 100 to 300 milliseconds,” said Feinberg.

With its leap in speed, researchers now believe the accelerated MRI could have an immediate impact on the most ambitious project ever undertaken to study the human brain.

It’s dubbed the Human Connectome Project. Researchers at centers around the country are attempting to map the neural pathways that support human brain function, ultimately drawing a map of the brain’s communication network.

“We’re able to identify the networks much better and see more of them and more accurately,” said Feinberg.

And by understanding the pathways of a normal brain, researchers believe they may unearth clues to disorders ranging from autism to Alzheimer’s disease — a quest that’s now being accelerated by this new generation of MRI.

Hitachi Receives FDA Clearance for Widest Bore 1.5T MR System

The New Shape of MR

Echelon Oval is designed around the shape of the human body, allowing for an optimal patient experience with outstanding comfort, space and efficiency.

The game-changing 74cm oval bore is the widest 1.5T MR system available. Enhanced patient accessibility combined with Hitachi’s Workflow Integrated Technology (WIT), advanced imaging capabilities, and UltraPlus Customer Support, makes Echelon Oval an ideal solution for-improved workflow, greater diagnostic confidence, and increased cost-efficiencies.

Echelon Oval, the innovation that’s changing the shape of MR.



Hitachi Medical Systems received FDA clearance for its Echelon Oval 1.5T Ultra-Wide MR system. The Echelon Oval has a bore that is, as the name implies, oval-shaped, very much unlike conventional MRI systems which have a round bore.




WIT RF Coil System: Integrated coil system with 16 channels, optical RF transmission, and multiple coil connection points optimizes workflow and image quality while providing head-first or feet-first positioning for all imaging. Integrated Head and Body/Spine coils can be used individually or in combination with WIT anterior coils for comprehensive neuro and body imaging. Additional multi-element coils are designed for high quality extremity, general and specialty imaging.

All of this and Hitachi’s RADAR motion compensation capability—applicable on all coils,
in all body planes and with pulse sequence flexibility further ensure exquisite head to
toe imaging.

MRI revolutionized, breaking the sound barrier.

This research will revolutionize MRI as we know it!!


BETHESDA, Md., May 8, 2012 /PRNewswire via COMTEX/ — A team of scientists led by Dr. Stanley Fricke of the Children’s National Medical Center in Washington DC, broke the “Magnetic resonance imaging (MRI) sound barrier,” a finding that could lead to a hundred-fold increase in MRI speed, according to a new clinical study published this week in the peer-reviewed journal Medical Physics. “Our ultimate goal,” said Dr. Fricke, “is to image small children in seconds rather than minutes. In this way children will not need to be anesthetized prior to imaging.”

Past attempts to substantially accelerate MR imaging failed because gradient pulse sequences (the technology responsible for image formation in an MR machine) can cause twitching or more serious nerve stimulation. To prevent such unwanted and potentially dangerous side effects, the FDA and European regulators put in place limits on gradient strength and speed, based on older clinical studies that used relatively slow gradients. The new Medical Physics study used pulse sequences with rise times 100x faster than conventional MRI to prove that nerve stimulation could be eliminated by employing ultra-fast magnetic gradients.

According to Dr. Fricke, “the old speed limits may need to be reviewed in light of this new data. The new technology could lead to the adoption of MRI as a first-line method of assessing coronary artery disease, improve high-resolution brain mapping, and implement low-cost dental MRI as a potential non-ionizing-radiation alternative to x-rays.” Dr. Benjamin Shapiro, a team member from University of Maryland’s Fischell Department of Bioengineering, has proposed using the high gradients with magnetic nanoparticles to improve image-guided minimally-invasive therapy.

The landmark study, funded by the National Institute of Neurological Disorders and Stroke and the National Heart Lung and Blood Institute, challenges decades of conventional wisdom in the MRI field. Increasing the speed and magnitude of gradients has been a long-sought goal in the medical imaging community. “Prior clinical studies concluded that nerve stimulation prevented the use of strong gradient pulse sequences,” commented Dr. Fricke. He characterized the speed breakthrough as both metaphorically and literally “breaking the sound barrier,” since the higher MRI frequency is beyond human hearing ability.

The ultra-strong and ultra-fast gradient technology to break the MRI sound barrier was produced with industry-leading instrumentation created by Weinberg Medical Physics LLC, an innovative R&D lab in Bethesda, Maryland. Last week, the company was granted a patent for non-stimulating magnetic gradient generation methods.
