Magnetic Resonance Imaging and Intracranial Aneurysm clips

Six different types of Intracranial Aneurysm Clips representative of those used in South Australian Neurosurgical practice were tested for their ferromagnetic quality measured by deflection at the portal of a 1.0 Tesla superconductive M.R.I. unit. One clip (Sugita) exhibited no deflection and was regarded as non-ferromagnetic. Radiographic identification of the Sugita Intracranial Aneurysm clip appears possible.
