Just thought you might find this of interest...
Prof Peter Mansfield of Nottingham University in the UK has just announced that a new MRI unit called the Seven Tesla (7T) is now fully installed within the University complex. It is currently the only one in the UK (not sure about worldwide?) of its type having a magnetic field 140,000 times greater than the gravity of Earth. It weighs 40 tonnes and has to be shielded in concrete and 200 tonnes of iron to prevent interference with other magnetic sources such as compasses etc. for miles around.
This new unit is claimed to provide an astonishing amplification of detail with finer resolution resulting in a remarkable degree of enhanced image quality thus greatly assisting in the diagnosis of medical conditions such as acoustic neuromas
I think I might be heading for Nottingham for my next scan!
