Abstract
A patient bed (,) of an MR imaging apparatus is provided with a tube (,) through which pre-polarised fluid can be injected into a patient in order to improve contrast when imaging veins, arteries or other vessels in the body. Fluid is delivered from pump (,) into a high field polarising magnet (,) and along a tube (,) to the patient. Valve (,) is provided so that fluid in the tube (,) downstream of the pre-polarised fluid can be discarded rather than being injected in the patient, and is associated with a reservoir into which the fluid to be discarded and the pre-polarised fluid can be rapidly injected. Then, when the pre-polarised fluid is injected into the patient, its magnetisation has not deteriorated by as much as it would have done if the tube (,) had been directly connected into the patient.
