RE: Gandolinium-Free Imaging: 'Licence to Print Money'2 Jul 2019 18:46
It's worth noting that IQAI already offers reduced-gadolinium imaging, a major selling point, although it's ultimately committed to introducing a gadolinium-free alternative, as outlined in its recent annual report (extract below). -

"Gadolinium free imaging
Gadolinium is a rare earth metal which has paramagnetic properties. When used in conjunction with Magnetic Resonance Imaging ("MRI"), it can enhance the visualisation of soft tissues such as those found in the brain. Compounds formulated using gadolinium are the primary contrast agents used in radiology. The clinical literature is replete with articles highlighting Nephrogenic Systemic Fibrosis (NSF) and recent findings about gadolinium deposition in the brain.
While concerns about the long-term toxicity effects of gadolinium-based contrast agents ("GBCA") are unknown and more research is needed to substantiate any link to health issues, radiologists would like to move away from using GBCAs if a suitable alternative could be offered. This would eliminate any potential risks of using GBCAs, streamline clinical workflows and save significant material expense.
IB has filed a patent for gadolinium free imaging. Using deep learning networks, analogous images can be generated from anatomical and functional images acquired without any exogenous contrast material. Though the development and regulatory timelines are significant, the Company already has technologies that reduce the use of GBCAs. Specifically, the Company's patented Simultaneous Perfusion Imaging with Consecutive Echoes ("SPICE") technology eliminates one (preload) dose of the required two administrations of GBCA during image acquisition for brain tumour perfusion analysis. This patent has the additional benefit of providing both dynamic susceptibility ("DSC") and dynamic contrast enhanced ("DCE") parameter maps using a single MR acquisition. Both DSC and DCE imaging provide biological and physiological information about the brain.
In addition, one of IB's founders, Kathleen Schmainda PhD, was the lead author for a study that appeared in the American Journal of Neuro Radiology in April 2019, "Moving Towards a Consensus DSC-MRI Protocol: Validation of A Low Flip Angle Single Dose Option as a Reference Standard for Brain Tumours". This study identified that using IB Software to process data acquired on 3T MRI systems configured with low-flip angle settings produced output comparable to the accepted double contrast dose method. Thus, the preload dose of contrast can be eliminated without compromising image quality. Moreover, the output was further enhanced when IB's exclusive machine-learned calibration technology was applied. The results of this study were presented at the 2018 ASNR Meeting and, more importantly, offers clinicians immediate access to a lower GBCA alternative.
While these two approaches offer instant reductions to GBCA use and
