Nano4Imaging was founded in 2011 in Aachen(Germany). Our MR compatible guide wire (MRWire) and MagnaFy technology enable to transfer part of current diagnostic and interventional procedures from X-ray and cathlab to the MRI suite. MRI has excellent diagnostic imaging capabilities, and does not expose patients and physicians to radiation such as X-Ray. However MRI compatible devices are lacking, and as a consequence surgeons continue to use other techniques for interventions or use radiation dependent techniques even in situations where MRI or ultrasound would be superior. Our current clinical focus is on cardiovascular interventions and more specifically on patients with congenital heart diseases (CHD). From interventions in this group we plan to extend our applications to diagnostics in wider patient groups and to interventional procedures (such as PTA) We closely collaborate with top hospitals all over the world to enable their efforts towards better patient treatment. Our know-how is based on synthesis and application of iron-based contrast agents as well as the logistics of clinical interventions and the needs for transition to MRI.
