SYSTEMS AND METHODS OF DELIVERING FLUIDS TO A PATIENT OF VARYING CONCENTRATION

摘要

A method for injection of an Imaging contrast into a patient, includes two to three phases having differing concentrations of contrast agent The first phase is injected for a first period of time The second and third phases are Injected for second and third period of times The osmolality of the second phase is higher than the osmolarity of the first phase The osmolarity of the third phase is lower than the osmolarity of the second phase In embodiments in which the contrast agent of the first phase Is of the same composition as the contrast agent of the second phase, the second concentration can be higher than the first concentration In embodiments in which the composition of the contrast agent of the third phase is the same as the composition of the contrast agent of the second phase, the third concentration can be lower than the second concentration
