Abstract
The meglumine salt of a urographic contrast agent is significantly more viscous than
the comparable sodium salt. To noninvasively deliver a bolus to some patients it is
often necessary to use a 21-guage needle. The inherent resistance of a 21-guage scalp
needle results in approximately a 60% increase in injection time for the meglumine
salt as opposed to the sodium salt.
