The planning and installation of a Superconductive Magnetic Resonance Imaging (M.R.I.) installation is described at the Royal Adelaide Hospital, Adelaide, South Australia. Tender specification, assessment of offers via criteria weighted analysis of technical and economic factors and the final recommendation for a 1.0 Tesla unit are discussed. Building and installation considerations are noted including fringe field effects, magnetic shielding, radiofrequency shielding, cryogens, metallic screening and specific considerations in the Magnet room.

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.
