New G-SPECT technology recognized by World Molecular Imaging Society

G-SPECT from MILabs
A new imaging system developed by MILabs reportedly offers a spatial resolution of less than 3 millimeters with a low dose and the ability to image fast tracer dynamics. The G-SPECT, which can also create 4-D movies, is still awaiting clinical approval — but is already turning heads.

Earlier this month, the World Molecular Imaging Society (WMIS) awarded its first Commercial Innovation of the Year Award at the 2015 World Molecular Imaging Congress (WMIC) to MILabs for their new modality.

For the award, 28 companies submit abstracts and then six semi-finalists were chosen to present their technologies at the congress, held Sept. 2 to 5 in Honolulu, Hawaii. WMIC attendees selected the winner via a vote.

Frederik Beekman, the chief executive officer of MILabs, which has its headquarters in The Netherlands, said that while G-SPECT has not yet been tested in humans, it has been shown to provide images that show much smaller structures than traditional SPECT systems, which may allow physicians to make more accurate diagnoses.

“Normally you don’t see that kind of small stuff with SPECT,” Beekman, who is also a researcher at the Technical University of Delft in The Netherlands, told HCB News.

In collaboration with the Erasmus Medical Center in Rotterdam using a resolution phantom, the G-SPECT clearly imaged 2.5-millimeter structures, with a competing commercial system imaging down to 7-millimeter structures.

The company uses a patented collimation technology, as well as a detector surface that is several times bigger than the standard, as well as “many more” detectors to take the images, Beekman said. The detector ring is also stationary, so instead of rotating around the patient, the detectors take a number of 3-D images quickly, creating a 4-D movie. It also has a scanning speed in the brain of about half a minute and, in some cases, it could go down to a fraction of a second. It can be used for diagnosis in cases of epilepsy, brain trauma, Parkinson’s and Alzheimer’s disease.

“The G-SPECT may become a game changer in the medical imaging of various disorders of, for example, the brain, kidneys or joints,” said Fred Verzijlbergen, who heads the nuclear medicine department at Erasmus Medical Center in Rotterdam, in a news release. “In one go, we will get a wealth of detailed information from a single SPECT scan. The difference in resolution from the current SPECT technology is so big that it is difficult to say how great the revolution is, that the G-SPECT unleashes. Now, of course, thorough scientific testing on large groups of patients should be given high priority.”

With the G-SPECT, this represents a move for MILabs from preclinical to clinical systems. Beekman says he hopes to have FDA and CE approval for clinical use by early next year.
